I have a BURp that just started running, but the idle process is getting 99% of the CPU time. BOINC believes BURP to be running, but blender is not actually doing anything.

X86 Family 6 model 5 Stepping 2 447 Mhz. XP SP2.

BTW, the system is a bit un responsive, and it appears that the HD is thrashing.

Am I right that you only have 127MB of memory installed in that system?

I believe so. I wasn't sure whether you had started a new batch or not. If you did, it is still not checking for RAM correctly.

BTW, after I aborted the WU, blender.exe was still running - so that bug is still there as well.

Well actually this is a new batch and the memory limit was 256 which makes me wonder why your machine got this one...

[Edit] Ok, after looking at a workunit on my own host I seem to know what has happened. The workunits were sent out with a wrong memory limit (100MB instead of 256MB).

[2nd Edit] Hm.. seems the BOINC documentation has an error in this particular area. The documentation says that the project needs to specify "rsc_mem_bound" but the code has "rsc_memory_bound" in it... Perhaps this has something to do with the issue.

Hi

I watched burp/blender on both my hosts with the same behavior A period of low cpu usage with lots of hard drive activity and no change in percent done ,followed by high cpu usage and low hard drive usage and a rapid rise in percent done. This cycle reputed several times, approximately 10. I assume this is the multiple renderings per frame and some sort of preparatory process.

But during these times I also suffer from an unresponsive computer and time marches on without CPU time increasing.

Ok, thanks for the feedback. I changed the variable in the tool that is used to create workunits. The next test-session (136) will show if it worked.
