1) Message boards : Problems and Bug Reports : S6 Directed Search (CasA) - File upload error (Message 112553)
Posted 1 day ago by Holmis
Thank you for the fast fix on a weekend and holiday!

I've just downloaded 2 new version 1.01 tasks and will report back about how they behave.

Both tasks finished and uploaded normally, waiting for validation now.

Looking at performance the new tasks take almost twice as long as the gravity wave search currently running on Einstein, I assume this is by design.

Good work and once again thank you for the fast response and fix!

Hi

Noticed that a new gravity wave search was added and wanted to test a few tasks.
They seem to run fine all to the end but fail with a file upload error.

Task #839748 failed to upload the file "h1_0050.80_S6Direct__S6CasAa_50.9Hz_9_0_1" resulting in a computation error.

The event log in Boinc for that tasks finishing is as follows:

19/05/2013 00:55:47 | Albert@Home | Computation for task h1_0050.80_S6Direct__S6CasAa_50.9Hz_9_0 finished

When I checked the project directory I found a few files that ended with "-LV" e.g. "h1_0050.80_S6Direct__S6CasAa_50.9Hz_9_0_0-LV" and I'm now wondering if these are actually the files that should have been uploaded.

I also noticed that the plan class has a minor spelling error in the word "search".

4) Message boards : Problems and Bug Reports : RPC error: Peer certificate cannot be authenticated... (Message 112494)
Posted 18 days ago by Holmis
03/05/2013 08:24:08 | Albert@Home | Scheduler request failed: Peer certificate cannot be authenticated with given CA certificates

Host 5367: Windows 7, BOINC v7.0.64 - it was working until 2 May 2013 20:25:34 UTC (yesterday evening), and other projects (including Einstein) are OK.


Same problem here too, my last successful contact was at 22:47:55 UTC. My host is 2267, also a Win 7 (x64), Boinc 7.0.64.
5) Message boards : Problems and Bug Reports : FGRP application v 1.05 (OPENCL) feedback thread (Message 112392)
Posted 59 days ago by Holmis
I've got to say I'm quite impressed with the Nvidia OpenCL app! If I compare the times I get here to the times the CPU-app produce over at Einstein the result is:
The FGRP CPU-app over at Einstein takes about 5700-6000s per task.
The Nvidia OpenCL app here takes about 1300s per task.

I also believe this app has the potential to be much better as the current version use a full CPU core and only loads my GTX660Ti to about 30% and that load comes in bursts. Hopefully this can be improved in future releases.

Keep up the good work!

Nice, looking forward to it! =)

Posted 82 days ago by Holmis
I was one of the users who had to uninstall the OpenCL part of the Intel graphics driver when I used Boinc 7.0.28 or all CUDA-task would fail.

I'm now running Boinc 7.0.52 where some bugs concerning Intel GPUs have been fixed and can now successfully run work on both my Nvidia card over at Einstein at the same time as I've been testing a beta-app on Seti@home that runs on the Intel HD Graphics 4000. A few problems exist with either the app or Intels drivers as can be seen in this thread over at Seti.

So there should be enough support in the later Boinc-builds to try this.

Posted 191 days ago by Holmis
Hi

So far the BRP v1.31 has ran quite nicely on my host (id 2267).
But I do have two WU that looks a bit interesting from a testing stand point, namely:

WU id: 143172 with 3 inconclusive so far, 2 CUDA and one OpenCL

and

WU id: 147263 with 2 inconclusive, both CUDA

Posted 267 days ago by Holmis
How bout a single work unit?I want to see if a 660Ti is faster than a 580gtx/

Got hold of 2 BRP4-tasks and ran them one at a time on my over clocked GTX660Ti (Core@1201.9 MHz).
Run time: 1183.69 and 1175.39 seconds for an average of 1179.54 s.
GPU load ~84%.
This on Win7 x64, PCI-E 3.0x16.

I'd like to test that but as of right now I can't get any more work for BRP4, probably because the server status pages says 0 tasks to send...
