Message 57697 - Posted: 30 Oct 2021 | 19:13:27 UTC

Hi!

I am new to GPUGRID, so this might be a hasty question...
WUs were readily coming to my hosts until 25th of October - no WUs since then (no matter Linux or Win).
I saw WUs were available and were sent to other hosts/users.

Is this normal behaviour for GPUGRID or did something go wrong with my computers/hosts/boinc....?

Any comments or explanation are appreciated.

well, you will need to get used to this situation: tasks available for some time, and then no tasks available for some time.

However, it would of course be nice if someone from the team could give a least a vague prediction as to when new tasks will be ready for download.
Will this be in about 1 week, 2 weeks, 1 month, ... ?

Would help many volunteers to make some plans for their GPU use.

If you want work, go to preferences and select beta applications and the PythonGPU application.

I've been getting tons of work every day.

I get tons of work units, though whether they should be characterized as work is another matter.

But one has been running for 45 minutes, though it is a _5, so still suspect.

and they are being crunched successfully?

If I look at Jim1348's task list, I am not really convinced :-(

I have had a half dozen crunch successfully and one actually ran for the full length of the parameter test and was awarded credits of normal value for the full run length.

Keith have you managed to watch one of these Python GPU tasks while it was running? I'm still wondering if these are using the GPU yet.

the last batch (several months ago) of beta tasks only used the CPU and never ran anything on the GPU despite being labelled as a GPU workunit.

okay, I'll give it a try.
Since it's cuda 1121, it should work on Ampere cards, right?

Yes I watched several while they were running in nvidia-smi. Only saw about 31% utilization and about 200Mb of RAM used. Doesn't look like the tasks used much of the gpu for the tasks that couldn't complete fully.

The one task that ran normally for 3146 seconds and had what looks like a normal BOINC result finish I didn't see because I was out of town at the eye doctor this morning.

That is the one I would have liked to look with nvidia-smi while it was running at the end of its run.

I have tried to download Python tasks since yesterday afternoon, none so far.
Only later it occurred to me that these tasks are Linux only at this point, right?
My system is Windows10

@Keith Mayers: Thanks for feedback. I have all the settings (tick marks) turned on in GPUGRID preferences (from the time I have joined this project).

Do you have to install some special software (depending if it is a Python, ACEMD... task)?

Still no work since 25th of October. Bummer, I just received rtx3080 a week ago :(

Message 57746 - Posted: 4 Nov 2021 | 8:26:44 UTC

I stand corrected (was at work last two days, didn't check properly).
I received 3 Python tasks (error) and one ACEMD in last two days - but all came to my Linux machine.

So I still have this question:
Do I need to install some additional software on Windows machine (or was it just a coincidence that WUs came only to Linux machine)?

Thanks for help.

most probably it was NO coincidence that the Python task came to your Linux machine. Provided that it only runs on Linux, which I am almost sure, only Linux machines will receive these tasks.
And there is nothing you can install on your Windows machine to make a Linux task run on it :-(

The new PythonGPU application is beta still at this time and only available to Linux hosts.

It was the same way with the new acemd3 application, they start out as beta for only Linux hosts then get brought to Mainline and applications for both Windows and Linux are created.

You shouldn't have to install anything. The tasks are bundled with all the support dependencies the task needs. That is what is determined in the beta phase on Linux hosts.

We found out that the libboost 1.74 library was needed to have the tasks complete successfully and we added that library in manually. But the mainline application released now for all hosts has that package included in the task bundle now.

You just have to be patient while the Linux hosts work out the bugs for the developers. I'm sure the python apps will come shortly for Windows host.

In case, you didn't notice, we picked up a new developer scientist for the python machine learning applications. New blood for the project which is very good.

most of the recent tasks were dealing with the Python tasks.

To come back to the topic of this thread, though: can anyone tell when distribution of ACEMD tasks will be resumed?

Since the topic of this thread is "No WU's since 5 days" and there has been work in fact every day till today, (PythonGPU), maybe if you are the OP, you should retitle the thread to "No acemd3 WU's since 5 days"

The acemd3 work has been spotty since the summer. It comes in bursts. My last acemd3 task was Nov. 1.
