Boinc won't ask for work from a project if there are tasks from that project suspended, Full stop, Why ask for fresh work when there are tasks suspended.

So... if I want to keep Einstein as a backup project (for my 2 beefier GPUs), while also keeping it as a main project (for my GTS 240), then I should set the Resource Share to 0 (obviously), but... if I don't want to "chew through and error" those task types on my GTS 240, I should now also change my project settings to not do work for that app, right?

No, all you need to do is set an <exclude_gpu> for that GPU, for that appname in your cc_config.xml:

Client configuration

Since I believe you were the one that convinced DA to introduce this feature, you'd know that already, ;-)

Maybe there is a particular order in which one is supposed to upgrade NVIDIA and AMD drivers?

Over at Seti it has been said that the AMD drivers first then the NVIDIA.

Strange that, I always said the otherway around, and the Seti observation probably came from me in the first place.
(At one point both Nvidia and AMD drivers would both install OpenCl.dll overwriting each other, Raistmers's AMD OpenCL MB app would produce weakily similar/inconclusives results when the Nvidia's OpenCL dll was installed last,
so for his AMD OpenCL MB app to produce good results the AMD drivers had to be installed last)

These are the different packages for Debian:

Done ~70 v1.07 (GWopencl-ati-Beta) tasks on my HD7770 without problem, in a little over 1200 secs each, GPU is running a slot at PCI-E 2.0 x8 speed at present, and on APP runtime 1348.5

Gary, I did as you said and it is now well behaved.

Archae86, When I apt-get install boinc-manager the return is that I already have the latest version.

Thank you all

JoeB

What version there is in the repository depends on the distro's OS version, you might need to go into it's software centre, or use Synaptic to select a later backport,

What distro? and what version?

And more importantly: does this still happen?

That shouldn't be possible at the moment:

For the moment the beta test app versions are all disabled, so no new work should be distributed for them.


My i7-2600K has just picked up normal (CasA) v1.05 (SSE2) work even through Run beta is selected.

8) Message boards : Wish List : Android devices have GPUs that support openCL (Message 130497)
Posted 7 days ago by Claggy
I know I wish for the future now, but it would be nice to utilize the GPU's in tablets and phones. My tablet's very capable GPU sits idle while I compute other BOINC projects on 4 CPU's.

WHEN

Nothing to do with Einstein that is.

The Boinc developers already have that idea:

Android/BOINC development items

Feasability of GPU computation, e.g. LG Nexus 4's GPU Adreno320 supports openCL 1.2

Google seems to push RenderScript? over openCL support on Android...


Watch this space, it may take a while, unless you're a developer and you're going to implement it for them.

Some remaining development tasks. Please contact me (David Anderson) and post to boinc_dev if you want to help.

I've reported the same for Nvidia in the News thread.

It is currently available for Windows (32 Bit) and Linux (64 Bit) only, and you should have a card which supports double precision FP in hardware.

On my Win 7 x64 i5-3210M/GT650M/Intel_Graphics_HD4000 host I'm getting:

I've already got CPU beta CasA 1.06 work from this host, it is on the home venue, and Run beta is set to yes at that venue,
generally on Windows x64 projects supply x32 Cuda apps because there is no need for 64bit addressing, and there is a slowdown running 64bit Cuda apps because of the 64bit addressing.
