(moderation:
Hi all. I check my crunching results every few weeks. I just checked today and saw that my Einstein hasn't grabbed new work for 2 weeks. I restarted my computer and clicked the "update" command it just said "communication deferred".
My other crunching projects are fine. What is happening?
My machine:
1) 64 bit Linux Kubuntu 14.04, Kernel 3.13.0.85 generic, Intel i3 540 @ 3.07 ghz, 3.2 gb ram
2) Nvidia GeForce GTS GT 250 (Yes, GPU computing is enabled as it always has been)
Any thoughts?

In the last contact log for your computer this message can be seen:
I don't think that message is fully accurate but it gives a hint to the problem. The new FGRP GPU tasks require double precision floating point support and according to what AgentB posted here your Nvidia GTS 250 doesn't support it, so I don't think trying to update the GPU driver will help, but you could always try.

I suggest you try a driver upgrade. I got that exact message on a host with a GTX 1060 and a GTX 1070 (rather modern cards) which was running driver 372.54 (not old at all). On rebooting after upgrading the driver to the latest then available for my configuration I immediately got work. Possibly that was not cause and effect, but I think it worth your while to try.

I will look for a driver upgrade. If I can't find one then is it safe to say I can no longer use my GT 250 for this project?

Yes, without support for double precision you can't run the new GPU work. There's always CPU work to be done so the machine won't be useless.

I found this thread because I was looking for something similar to what I'm seeing. I'm getting no new work on Einstein (GPU only), but my Milkyway (CPU only) is going gangbusters. I'm running Kubuntu 14.04.5 LTS 64-bit with current update 4.4 series HWE kernel on a Core2Quad/8GB RAM, with an nVidia GTx750 and driver 367.57, the newest driver Kubuntu offers me (generally the newest one the repo maintainers believe to be adequately stable, or adequately tested -- not always the same thing, especially on a release that would be EOL if not for LTS status).
Should I be manually searching the repos for a newer driver than this "recommended" version? Or looking for some other problem? I found a host log entry as follows:

This should not be true. Double precision is only required for the last stage of computation, and if this isn't supported by the GPU, this part is ran on the CPU.

Your case you have these drivers installed, but server log shows insufficient VRAM.

This should be fixed after the holidays, when Christian releases the Beta versions with lower RAM requirements (~768MB),

Thanks, Bernd and AgentB -- this seems a little surprising, given the Einstein GPU tasks were working fine on my GTX750 less than two weeks ago. I'm pretty sure I haven't lost any VRAM. However, if there was a client update that bumped the RAM requirements, that would to it. I'll watch for the next update and see if I start getting tasks again.

Two weeks ago you were running the BRP4G application, which has just finished and which needed less VRAM. The new application FGRPB1G needs more VRAM, so cannot run until the next update which hopefully will help us here.
