      This is a report not a problem. :)

      Runtimes on a HD5770, 2 tasks at a time.

      App Average of Count of Run Time(s) results Binary Radio Pulsar Search (Arecibo) v1.24 (opencl-ati) 14490.90 38 Binary Radio Pulsar Search (Arecibo) v1.28 (opencl-ati) 6105.84 7


      Quite in improvement, I would say. Next step would be collecting a few more results on the 1.28 app, after that reverting to running one task at a time.

        Today I installed latest AMD-drivers 12.8. Runtimes on my HD6950 increased from ~3200 sec's (2wu's) to ~3770 sec's (2 wu's).
        Will switch back to 12.6

          App v1.28 halved both my GPU and CPU run times. From ~4,600 seconds GPU and ~750 seconds CPU to ~2,300 seconds GPU and ~370 seconds CPU. Thumbs up. AMD HD6850, 2GB.

            Alex,

            Saw the same problem with 12.8 -> increased run times. I run Win7 64bit. I don't know why but I changed from "Balanced" performance to "High" performance under "Power Options" and saw run times return to the 12.6 values. This was on Milky Way at Home. I haven't timed Einstein yet.

              After update E@H OpenCL application from 1.24 to version 1.28 error with the lack of free memory at once disappeared (which confirms that the problem was not in amount of free RAM, but a bug - in the application or in the AMD drivers or probably both).

              But 1.28 app still not working - just another error in all Wus:
              http://einstein.phys.uwm.edu/results.php?hostid=2896418
              [15:51:43][3012][ERROR] Error during OpenCL kernel setup: HSFFB (error: -5)

              or

              And POEM@Home OpenCL app still work fine on same hard&soft:

              P.S.

                For the developers, so far I've found that this exit code 2019 is the same as There was an error while deleting the color transform. (0x7e3) - exit code 2019 (0x7e3) that I had on Albert. Ask Oliver how he fixed that.

                  still no dice for me on HD5670/winXP32.
                  I get the same "color transform" error #2019 from the earlier 1.24 app.

                      Hmm, you right.
                      More exactly - at 1.24 app was 2 errors:
                      -Demodulation failed (error: 2013)! - this related to bug with lack of free RAM (when lot of free RAM actually)
                      -Demodulation failed (error: 2019)!

                      At 1.28 app first error (2013) gone, but 2019 still persist.

                        I run einstein in the background & pause it when I need to do processor intensive work. I recently started getting WU's for the gpu but these won't pause when I need to do graphics intensive work. The Boinc manager tasks status is listed as suspended, but the task keeps on using the gpu. I had to abort the task to get on with work. Do you have any suggestions so that I won't have to continue to abort opencl-ati-lion tasks?

                          Interesting, thanks for the report. The one result that was reported shows that the app crashed somewhere in the drivers at it seems, maybe at the moment it was suspended??

                          It would be interesting to know whether other Mac users are seeing this as well or whether it was a fluke.

                          Cheers

                            Hello all.
                            Since the update I have a AMD 12.8 boinc 7.0.28 and incompatibility with my graphics card HD 5450. In fact as soon as I run Boinc Manager, I immediately blue screen and shutdown. This was not the case with version 12.6.
                            Someone you have that problem ..??
                            I have a board version 12.6 ..??

                            For now and until the problem is solved, I have to work in safe mode with networking support.
                            With this solution, of course, I can not use the GPU.

                            I wonder if it takes one of modiffication boinc or wait for a change of AMD, or returned to the version 12.6 (I said with the old version, the problem of error in the color change appeared to be resolved, since my last GPU WU been validated as successful.)

                              You are running XP on both pc's.

                              As posted in an other thread, the latest amd driver version for XP that supports open-cl is 12.1
                              Another reason to avoid 12.8 is that crunching time increases signisficant.

                                I run einstein in the background & pause it when I need to do processor intensive work. I recently started getting WU's for the gpu but these won't pause when I need to do graphics intensive work. The Boinc manager tasks status is listed as suspended, but the task keeps on using the gpu. I had to abort the task to get on with work. Do you have any suggestions so that I won't have to continue to abort opencl-ati-lion tasks?


                                Same here, MacOS X 10.7 AMD Radeon HD 6750M 512 MB.

                                I'm sorry to have checked Einstein's "Won't get new tasks" due to sluggish GPU. :-(

                                    This report is a little vague.
                                    I've got an Imac with a Radeeon HD 6770M running Lion 10.7.4

                                    I've had to turn off GPU processing because I noticed that playing flash video (you tube) while doing openCL processing had a tendency to hang the GPU.
                                    The machine hangs hard (mouse pointer still moves but everything else is locked up) and has to be powered off.

                                    Its not completely reproducable. It tends to happen after video has been playing for a couple of minutes. But has happened multiple times.

                                    I assume its the openCL that causing it since it only started happening once the opencl work unit appeared. And its stopped since I unsubscribed from the openCL workunits. But its not a huge sample set.

                                    Anyone else noticed issues?

                                      You could try the option to not "use GPU while machine is in use".
                                      That way the the GPU tasks should only run when your machine is idle eg overnight.

                                        Hi!

                                        Especially for notebooks, the GPU load can be quite nagging: slow down of the user interface, heat and fan noise. I really like that BOINC now has the option to selectively suspend the GPU in the "Activity" menu. So you can, for example, leave GPU suspended except when you really don't care (say at night). You will still get a lot more science done when using the GPU app during the night only compared to all-day CPU-only operation.

                                        Cheers

                                          Hi! The app "Binary Radio Pulsar Search (Arecibo) v1.28 (opencl-ati)" crash on my laptop every time it started. I don't know how to get further detail (e.g. the log file of the app) in order to get this fixed. The OS is Windows 7 Home Basic, ATI driver version: 8.951.0.0 on ATI HD 7730M. And it seems that this laptop can choose which video card to use. There is another integrated Intel HD Graphics 4000. I'm to quite sure about that. What should I do?

                                            Hi!

                                            Is that the most recent driver available for that card? Updating the driver (usually) can't hurt.

                                            Unfortunately the app isn't producing any meaningful diagnostic messages before it terminates.

                                            Are you subscribed to other BOINC projects which offer OpenCL apps for ATI/AMD cards? I wonder whether this is a general problem with the OpenCL support on this particular host or it is specific to teh E@H app.

                                              Hi, Bikeman

                                              I don't think it would be cause by an old version of ATI driver, because I just bought it no more than 3 month ago. It is a brand new 3rd gen i7 core laptop. The driver should not be too old to make such a crash. I subscribed SETI@Home as well. And there are tasks using ATI opencl app ( AstroPulse v6.04 opencl_ati_100 ). It works fine so far. Not sure if it will crash as well as it is still running.

                                              So sorry to hear that no log could be find. Thank you all the same.

                                                In the past when I tested older laptops by running Einsteins or LHC/T4T they did have those problems but the quad-core I am on right now never has any problem and it runs 2-core T4T,LHC,and 2 Einstein BRP4 Cuda's 24/7 with no heat problems and of course no fan problem since June 15th

                                                Now this GeForce and processor isn't quite the same as my desktops with nVidia 550ti overclocked or 660Ti superclocked.

                                                So far this is a nice laptop to have.

                                                  To be complete here, Sumtec has since his post posted at Seti that his system BSODs when running Astropulse tasks on his AMD. I'm asking him to uninstall his Intel HD Graphics 4000 drivers, as I fear that these interfere with the OpenCL drivers on his system (I am investigating multiple similar situations for the BOINC developers).

                                                    Thanks Jord, that was valuable information. Let's hope this will be fixed eventually when BOINC supports Intel OpenCL.

                                                      Reading NVidia's 306.02-win8-win7-winvista-desktop-release-notes.pdf, released 28 August 2012, it looks as if NVidia is not immune to this problem.

                                                      There are numerous notes (mostly for Windows 8) like:

                                                      [Optimus notebook]: When attempting to install the NVIDIA driver over a prior driver version, the installation may fail with a blue-screen crash pointing to dxgkrnl.sys. [1000723]

                                                      This intermittent issue occurs on only a small number of systems.
                                                      • To avoid this issue, first remove the older NVIDIA driver using Add/Remove Programs in the Windows Control Panel, then install the new driver using NVIDIA setup.exe.
                                                      • If you encounter this issue, boot to Safe Mode, then remove the older NVIDIA driver using Add/Remove Programs in the Windows Control Panel. Install the new NVIDIA driver using NVIDIA setup.exe.


                                                      [RH - the 'Optimus' trademark refers to the dual technology where an NVidia GPU is teamed with an Intel HD graphics chipset]

                                                        Hi guys,

                                                        Prior to this new app i was having problems getting anymore than 75% gpu load, this includes crunching simultaneous gpu wu's. I tried leaving a cpu core dedicated to the gpu units etc but again failed to get beyond 75% gpu usage.

                                                        It seems 1.28 has totally resolved the above issue & im now at 90% of gpu load with massive reductions in gpu crunch time.

                                                        The only issue with 1.28 i encountered was comodo firewall blocking it, a number of wu's exited with the error couldn't start CreateProcess() failed - Access is denied. (0x5): -148, this was easily corrected by creating a rule to allow the new app in the firewall.

                                                        Nice work ppl,
                                                        Jason

                                                          I've just reached the CUDA v1.28 batch on my new GTX 670 (Kepler) - host 5744895.

                                                          Seamless transition, with runtime dropping 25% (from ~2400 seconds to ~1800 seconds) and CPU usage dropping 50% (~700 seconds to ~350 seconds). I'm running two tasks at a time, so that's closing on 100 tasks per day - what was the speed limit again for this project?

                                                          Seriously - great job, no problems at all. You won't see quite that throughput, because I run other projects on the card too, but maybe I'll get a finder's certificate one day...

                                                            You're more likely to get one than me since I have just one lowly 550Ti doing BRP4 tasks :-). It has a cache of 1.25 branded tasks (running 2 at a time) so I suspended them all to allow a couple of 1.28s to start. The first pair have just now completed and the improvement is very pleasing.

                                                            Run time has gone from approximately 5600s to 4100s and the CPU time from approximately 1500s to 1100s. The card is in a host with a Q9400 quad core with one core free.

                                                            I'm very tempted to set up AP to run the remaining 1.25 tasks with the new app but it's getting late here and I need to go home. Maybe in the morning if I get really keen ...

                                                              Don't need AP for that - provided you have the new app's <app_version> and associated files already present, as you do, you can simply change the version numbers in client_state.

                                                              I don't recommend that you do this unless you really know what you're doing (as Gary does), but...

                                                              Compare the <result> blocks for your v1.25 and v1.28 tasks, paying particular attention to <platform>, <version_num>, and <plan_class>. If they match, a simple replace from <version_num>125</version_num> to <version_num>128</version_num> will do the trick.

                                                              You need to replace that string in both the <workunit> and <result> sections for cached tasks, but avoid changing it in the <app_version> description - you can't do a complete global replace. It's probably best to report completed tasks first, and avoid 'rebranding' (as we call it at SETI) tasks in progress. Following Gary's lead, by suspending v1.25 tasks first and starting the v1.28 tasks, would ensure that.

If they match, a simple replace from <version_num>125</version_num> to <version_num>128</version_num> will do the trick.

                                                                  You need to replace that string in both the <workunit> and <result> sections for cached tasks, but avoid changing it in the <app_version> description - you can't do a complete global replace. It's probably best to report completed tasks first, and avoid 'rebranding' (as we call it at SETI) tasks in progress. Following Gary's lead, by suspending v1.25 tasks first and starting the v1.28 tasks, would ensure that.


                                                                  Is not possible to do just a clever renaming of the executables? (finishing first the WUs that already started to avoid the "rebranding" thing)

                                                                    I'm very tempted to set up AP to run the remaining 1.25 tasks with the new app but it's getting late here and I need to go home. Maybe in the morning if I get really keen ...

                                                                    I had a similar temptation so I just wait until running tasks have finished and then reset the project. After resetting boinc resent all remain tasks with 1.28 version marks.

                                                                    I hoped you backed up all the p2030.20110117.*.bin4 data files before you reset the project, and restored them afterwards? That saves one heck of a lot of download bandwidth, both at your end and for the project - and it gets your crunching restarted a lot quicker.

                                                                      Another way might be to re-version the current 125 <app_version> block to something unused like <version_num>99</version_num>, and replace it with a duplicate of the 128 <app_version> renumbered 125. That would keep all the older files and signatures in place, but process 125 'branded' work with the files from 128.

Beta driver 306.02 appears to be giving a 5-6% performance improvement with the new app over previous drivers that I tried. I am seeing this improvement via a Fermi card.

I don't follow Seti at all and I've never tried 'rebranding' tasks before so I wasn't sure if there were any complications with doing something like this. In this case around 40 tasks have now been successfully rebranded and things seem to be chugging along just fine.

After running all of them, it started a Collazt WU (a 0% share/backup project for me) which began to run normally. Restarting boinc didn't help; but everything returned to normal after I rebooted.

                                                                                Occasionally we have a few data files which contain garbage or "semi-garbage", so that the app finds less candidates in the data than the validator thinks is healthy. We try to kill those units from time to time, but we are kind of conservative, trying to not kill anything unless we are really really sure it's one of the "hopeless" batches.

                                                                                This particular thing seems to be a marginal case, because it has one unit that (probably erroneously) found a candidate and thus passed initial validation. That kept it from qualifying for being flagged as "hopeless".

                                                                                    I've got an Imac with a Radeeon HD 6770M running Lion 10.7.4

                                                                                    I've had to turn off GPU processing because I noticed that playing flash video (you tube) while doing openCL processing had a tendency to hang the GPU.
                                                                                    The machine hangs hard (mouse pointer still moves but everything else is locked up) and has to be powered off.

                                                                                    Its not completely reproducable. It tends to happen after video has been playing for a couple of minutes. But has happened multiple times.

                                                                                    I assume its the openCL that causing it since it only started happening once the opencl work unit appeared. And its stopped since I unsubscribed from the openCL workunits. But its not a huge sample set.

                                                                                    Anyone else noticed issues?




                                                                                    Yes, same here for iMac with Radeon 6770 / 512MB running Mountain Lion, the machine hangs when using Flash (hard reboot is needed) but knowing Flash and its bugs it's no surprise for me. I am crunching with GPU while computer is used because there's no lag for regular work. When I intend to use Flash I usually click on BM "Snooze GPU". I also keep 1 CPU for GPU instructions only - out of 4 CPUs only 3 are utilized for CPU crunching. Machine has no issues if no Flash is used, so far I am very happy with the results.

                                                                                      In my case the BRP 1.28 on the 560Ti host leads to a DCF of 0.8 while the S6LV1 leads to a DCF of 1.7... I know that the speeds are some kind of predefined averages but AFAIK is still using the speed of the previous version...
                                                                                      With the DCF varying so much BOINC asks for more CPU work every time I finish a BRP task causing (I guess) unneeded extra load on the schedullers/download servers...

                                                                                            I'll start this by saying that as long as you got you computers hidden anyone who would like to help you with this problem has to work a bit extra for the diagnosis, but thanks to the log you posted I could take the hostid and locate the records for that host anyway.

                                                                                            Here is a link to host 5848606 for anyone else that's interested

                                                                                                AFAIK, that value is not a measured benchmark. BOINC gets that value doing some maths based on the model of the GPU and other things...

Or because htey find it was wrong and improoved them in new versions... or something alike...

                                                                                                  Does anybody here have any experience of running the opencl-ati application (any version) under a Windows ATI driver in the range 11.7-11.11 inclusive?

                                                                                                  Those are the drivers with APP OpenCL runtime support - misleadingly called 'SDK' by AMD - version 2.5

                                                                                                  I know those drivers are unpopular with AMD users, because that runtime uses the CPU inefficiently, but they still crop up sometimes. I'm getting reports from another project that not only are they inefficient, they can also cause science errors in an application running under BOINC. Could one of the mods/scientists tell if there are any indications of invalidated tasks in the database like that?

                                                                                                      I'm getting reports from another project that not only are they inefficient, they can also cause science errors in an application running under BOINC.

                                                                                                      I had a look at our DB and we currently don't have anyone (yep, zero that is) using those driver versions crunching OpenCL tasks on a Microsoft OS.

                                                                                                      The only OpenCL numerical stability issue I can remember right now are the native_sin/native_cos functions causing a lot of invalid results on 69xx Radeons for instance. These functions are hardware-dependent and the 69xx series seems to be very "bad" in this regard. Beware, Apple's FFT sample does use these functions...

                                                                                                                  However in OS X 10.8 Mountain Lion, it got worse to the point that WUs started to error out even AFTER GPU-intensive apps were exited.
