Intel HD Graphics 4600 can`t receive new GPU WUs since last week.Can you check it?

There is more than that, If you don't run compatible drivers, or have a HD Graphics 40** GPU then you won't get work:

It's not as if it wasn't announced:

thanks Bernd for fixing this as far as you can right now!


welcome!

There are actually three plan classes now used for Intel GPU app versions (see apps page):

- "opencl-intel_gpu": restricted to old hardware (up to HD 4000) or software (32 Bit Windows)

- "opencl-intel_gpu-new": restricted to drivers below 10.18.10.3907

- "opencl-intel_gpu-Beta": restricted to "Beta testers" ("Run Beta test application versions" -> "yes"), for testing new driver versions with new hardware

2) Message boards : Problems and Bug Reports : Old computer "stuck" in a list of machines I'm running (Message 138645)
Posted 3 days ago by Claggy
I've sold this computer almost two years ago but it is still being listed in the active computers list and I can't delete it because one completed task is "stuck" in the list.
It's this computer: http://einstein.phys.uwm.edu/show_host_detail.php?hostid=7175631

Can someone delete this old computer from the list? Thx in advance.

The task is shown in the database, but not the workunit.

Posted 9 days ago by Claggy
If you don't want to try and resolve the problems running BRP4 tasks on your HD4400 GPU then instead of aborting all of them go to your Einstein@home prefs and opt out of "Binary Radio Pulsar Search (Arecibo)" and you'll stop receiving them.

Or Deselect 'Use Intel GPU' and Boinc will stop asking for work for the Intel GPU.

So how long are tasks taking on the new Raspberry Pi2 as apposed to the old Pi's?
Obviously there can be four at a time, but how much faster is the neon ARM7 versus the ARM6 for Einstein@home.

I have i think 20 Arm cores crunching across various projects, Here they get:

My Pi2 running 2 up is coming in at around 68k secs:

http://einstein.phys.uwm.edu/results.php?hostid=11741356

One of my Parallellas running 2 up comes in with similar times:

http://einstein.phys.uwm.edu/results.php?hostid=11381548

My Samsung S5 mini on Android 4.4.2 (clocked at 1400MHz) comes in with similar times:

http://einstein.phys.uwm.edu/results.php?hostid=11667599

My 2012 Nexus 7 on Android 4.4.4 (clocked at 1200MHz) comes in 50k to 65k secs:
(only running three up, running three BRP tasks make it very laggy, so try and keep at least one task from another project running)

http://einstein.phys.uwm.edu/results.php?hostid=11543282

My 2012 HTC One S running Android 4.1.1 (clocked at 1500MHz) is fastest at around 27k secs, But produces eithier validate error, or Error while computing:
(I still think there's an api problem hanging around to do with power saving and critical sections)

http://einstein.phys.uwm.edu/results.php?hostid=9721755

My single core HTC Desire S at Albert on Android 2.2.2 (clocked at 998MHz) comes in at 82k Secs:

I don't have times for my Model B Pi at present.

Posted 17 days ago by Claggy
It is a recompile of the NEON app at E@H. The one on A@H, was, IIRC, exactly the same except it used a different version of FFTW, which turned out to be slower on almost all devices, therefore it never made it to E@H. I'll keep an eye on this, so far the NEONPIE version seems to run ok. Puzzling.

I've set it loose on Einstein again:

On Monday I'll try to have BOINC deliver the Android 5 "PIE" compliant version to all devices that can actually run it (Android 4.1+) and not just to Android 5 devices, which should make the transition a bit smoother from now on.

Is the 1.46 (NEONPIE) a rebuild of the 1.43 (NEON) app that's in use here, or the 1.44 (NEON) app that's in use at Albert?

I somehow suspect my Android 4.1.1 powered HTC One S is going to continue it's validate error run here it had with the 1.43 (NEON) app, now with the 1.46 (NEONPIE) app,
It has continued to crunch the 1.44 (NEON) app at Albert without major problem, the one 1.46 (NEONPIE) workunit it did there ended up validate error:

I've come across a PI 2 scheduler problem at Albert, the scheduler won't send Neon work, i've reported it there with the scheduler log:

Posted 20 days ago by Claggy
Until then, could you at least allow a setting that says send this computer CPU-only workunits, but no GPU workunits?

Every project has project preferences, included in those project preferences are 'Use CPU', 'Use Nvidia GPU', 'Use AMD/ATI GPU' and 'Use Intel GPU' preferences, Just deselect the one you don't want.

And don't say that'll effect your other computer, Each project has four locations/venues so you can set four different sets of computing, or project preferences, just move one of your computers to a different location/venue, and make preferences to suit it.

On the Einstein and Albert application pages the Binary Radio Pulsar Search has entries saying 'runnung on' as opposed to the correct 'running on'

It's got a couple of Neon tasks from here, and a couple of non-Neon tasks from Albert, just running two up at present:

Computer 11741356 at Einstein

COMPUTER 12650 at Albert

Cool, thx!

For perspective, I assume this is (yet) at stock CPU clock?

I wonder if you can still get the CPU temperature by

cat /sys/devices/virtual/thermal/thermal_zone*/temp

it would be interesting so see if it's getting any hotter than the old one.

HB

P.S.: still busy downloading Raspbian image ...


It's stock clock at present, i haven't got my spare heatsinks with me (they're at my work address), and didn't want to push it too hard yet,

This is what i got as a temp for the Pi 2 :

pi@raspberrypi ~ $ cat /sys/devices/virtual/thermal/thermal_zone*/temp
51920

and my original Model B with a pair of heatsinks and at stock clock gives (running my self compiled armv6 Stock Seti 7.0 app):

pi@raspberrypi ~ $ cat /sys/devices/virtual/thermal/thermal_zone*/temp
48692
