My GPU feels extremely neglected 😪

That is my standard line too. But at the moment, even they are having server problems in at least one of their locations, maybe two. No one seems to know exactly what is going on. Give them a week to figure it out.

I have decided to not restart or fiddle around with my machine. Let us see if it finishes successfully.
If I may say so, according to Afterburner my GPU is running four degrees centigrade hotter then the old WU or normal. As hot as Einstien@Home which is my backup when GPU Grid becomes lazy. Resources set at zero for Einstien.

Lost it. Power failure.

Dears, sorry for the slow progress but I determined (at least) a restart problem, and it is not related to the wrapper. It is Windows-only, CUDA 10 only, as far as I can tell from your reports, and manifests itself with the

"The periodic box size has decreased to less than twice the nonbonded cutoff."

message.

Unfortunately the root cause is hard to identify (may be external to our code).

I have compiled the wrapper myself (the binaries on the boinc page are old and had one important bug in variable substitution), but for now the failures seem unrelated.

It's a bit frustrating because everything else seems to work nicely.

If you are using openmm, line 375 of the CudaNonbondedUtilities.cpp source code is the following.

throw OpenMMException("The periodic box size has decreased to less than twice the nonbonded cutoff.");

Perhaps Peter Eastman can shed some light on this problem.

Hi,
there is not only CUDA 10.

Turing GPU cards are only able to do TEST Work Units at the moment.
You will need to change your GPUGRID settings to ensure only TEST Work Units are accepted for your Turing GPU.
The above errors occur for ACEMD2 Work units on Turing based cards.

How is it the other way round? Will the TEST Work Units work with cards prior Turing?

7.2.42 is really old (but latest on berkeley download). very likely the client is estimating wrong in addition to mis-identifying the cpu. apt-get under ubuntu 18.04 got me version 7.16.1 boinc

how did you get 7.16? I have same version of ubuntu but in repos see available only 7.9.3

He must have installed the ppa. The Ubuntu 18.04 distro only has BOINC 7.9.3.
Or he went to the source and compiled it on his own.

The TEST work units seem to be backward compatible.
My Pascal cards are receiving TEST work units and processing successfully. Interestingly, my Maxwell cards have not received a TEST work unit, but that could just be luck of the draw.
EDIT: The drivers on my Maxwell cards are quite old v388 - v391. This will explain why they are not receiving TEST work units. Nvidia driver version 418.39 or above is required for CUDA 10.1

Hi,
this is my last error on Windows after a suspend/resume action.

I hope it help.

Be careful with that one. It has not yet passed full release testing, and several serious bugs have been found already. Gianfranco is good at updating the PPA as bugs are eliminated, but doesn't increment the version number independently. I think the current PPA numbered 7.16.3 has all except one of the fixes needed: there will probably be at least a 7.16.4 before this saga is finished.

Thank you for the expert advice. So far 7.16.3 has worked on three other Ubuntu machines and one Win7. I did get a lot of extra downloads on WCG that I had never seen before, but expect that is a problem at their end(?). That is mainly because I have seen their "settings" reset every few months, and don't entirely trust their servers on that. Also, I just did a manual update of BOINC with no more extraneous work units downloaded, so it seems to be OK now.

When will there be some WUs that will run without erroring out on Windows machines? And not suck up an entire CPU in addition to the GPU?

Another error on Windows WU acemd3 test, without suspend/resume action.

They will always need their own CPU.
