1) Message boards : Project Staging Area : 2017 PRPNet March Challenge (Message 106103)
Posted 1036 days ago by TroubledBunnyProject donor
I think that if you're not sure if your computer is reliable that you should absolutely, positively, not be running PRPNet. Run BOINC tasks instead so that your results can be verified.

Thanks for the advice. I have been with PrimeGrid for some time now so I am aware as to the demands on the host machines. I actually only crunch on a couple of cores at a time.

I run BOINC on this machine unless there is a PRPNet challenge active. I was fortunate enough to find a megaprime using this host, but that was a relatively long time ago and as a i5-3570K it looks a little long in the tooth. Once the challenge is over I'll go back to ESP WUs. If I start throwing lots of errors on LLR WUs under BOINC then I will stop using this host on PRPNet.

What I should have asked is...
Does anyone else see this output: "Disregard last error. Result is reproducible and thus not a hardware problem."

I'm running two instances and haven't seen anything untoward on the other process.

Thanks,
Peter

What do you think? Should I buy a new cpu cooler? It does gurgle a lot :)

Task 738751589 timed out again lol.
Patience, patience. Could be worse I suppose, pity those peeps working SOBs.

Hi,
I'm a bit confused about the life of this WU:495833561.
It was initially sent to host 2 which errored out and was then sent to 3 (my host) and then to host 1.
Next, 3 returned a result and seemingly we then wait for 1 to return a result as double checker. All of that is as I would expect.
It then got sent to 4, 5 and 6 in that order, all of which either abandoned or aborted the WU.
But why was it sent to 4, 5 and 6 anyway? Will it be sent out again?
I'm sure I'm missing something but it eludes me.
Please don't waste time looking into this in any depth, it's just a curiosity to me.
Cheers,
Pete.

Sorry for my ignorance but what is a PLA-based compute engine?

Thanks for the answers. I wonder how many of your other readers understood.
Thanks again.
So the only feasible answer of the 7 as far as I can see is 2, which is what I guessed anyway ;)

* We'll be announcing PLA-based compute engine that will be able to complete the TRP sieve much quicker than the current CPU app.

Sorry for my ignorance but what is a PLA-based compute engine?
Thanks.

Great to see the resumption of another sub-project, pity it makes my GTX970 give horrid screen lag. I'll pass on this one I guess :(
Best of luck to all participants!

Apologies, I don't know what I did but I've re-run it and it works perfectly.
Sorry for any inconvenience caused,
Pete.

Remember you also need to run the "install", "update" and "start" batch file for the appropriate number of cores on your PC. Give it a go before the challenge to iron out any problems.

I noticed that the instanceid doesn't get changed by the batch files, is that field irrelevant?
Thanks,
Pete.
