Then another program has grabbed all the power.


Hi Reb,

Unfortunately, that's not the case - this particular PC *only* crunches BOINC - no other programs run on it.

So, there must be another answer?

I'll see what happens when the next tasks download and see what happens...thus far the short WU's are being crunched OK, and until the other day, the average WU's were OK too...

regards
Tim

The GPU is the problem. It needs a full CPU core so it can slow down the calculations. You dont need more RAM, a WU is taking around 65MB. If you run more than one project check the RAM usage, BU can take a lot.


Hi Reb,

But I set the BOINC Manager preferences to only use 75% of the CPU's available. So, only 3 are used...not 4. That means the GPU has full access to one CPU core, and I can then run some CPU tasks, plus some ASIC's.

I'll will reduce the CPU preference to (say) 30% and see if any more SRBase tasks complete OK.

finish file present too long

The computer was busy and had no free ressources to write the result file so it error out.


Hi Reb,

Thanks for your reply.

OK, so this is a quad-core Intel-CPU PC, running Win 7 (x64) with 2 Gb RAM and 400 Gb of free space on the HDD. Task manager shows lots of spare CPU capacity and very little paging to the hard drive.

Otherwise, it only runs BU (via ASIC's) and WU-Prop - that's it - it's a dedicated BOINC machine.....with 3 cores dedicated to CPU tasks. Plus, there's a GPU running Moo.

How can it need more "resources" than this, to give to SRBase? Do I need more RAM, because that's the only thing that I can do to "upgrade" this PC?

Application Sierpinski/Riesel Base - long 0.04. Latest BOINC Manager 7.4.42 (x64), running on Windows 7.

Four tasks have been at 100% for the past 12 hours or so. Screenshot attached. Should I worry, should I let them run, should I abort?

Thanks.

Hi all,

I just had this same issue - 2 WU's at 100% and "Waiting to run".....

In the meantime other project tasks started.....so, when I saw this I suspended these other tasks and BM re-started the SRBase WU's...but within seconds, both WU's were "Computation error"...so that's 4+ hours wasted.

http://srbase.myfirewall.org/sr5/result.php?resultid=34818184

These are both "Sierpinski / Riesel Base - average v0.04" WU's.

I haven't had this issue before, so do not know the reason - PC has been working fine before now:
