1) Message boards : Number crunching : LLR2 installed on all big LLR projects (Message 146460)

Just curious.
What kind of fault tolerance is built into the verification double check system, say the double check computer is overclocked and faulty. How does the server check for that?

I'm crunching 4 * 4 on my 16 core machines.


Try 16 tasks one thread. MT is not a good idea for SGS.


I disagree, on my 2400g system 4 core/8 thread, my best results are from doing 2 units at a time using 4 threads each.

I HAVE COMPLETED 4 TASKS BUT WHY I'M NOT ON TNE STATICS??????????


You will not show in the stats till your wingman has been completed and your task verified.

Edit: guess that is not the case. Misremembered. Carry on

I have been using colab. figured I would post up some numbers based on the different gpus I get. I have been able to get a single instance 12 hours a day or so and then a break of 12 hours. non gpu instances are available during that time, but I get timeouts faster, so don't bother.

t4 206 seconds

It looks like you are running windows 7. There is a known issue with windows update eating up a lot of processor time.

You might want to try the things suggested in this thread at anandtech forums and see if it helps.

6) Message boards : AP26 - AP27 Search : App testing (Message 96771)

Just tested the opencl64 app on my HD6950 1GB card.
All three tests completed successfully and took around 4 minutes each.
Windows 7 Running driver 15.7.1
So older VLIW4 card works even with only 1GB memory.

You are welcome. Glad you got it sorted.
8) Message boards : Problems and Help : Sierpinski Problem ESP/PSP/SoB (Sieve) Validate Error WU (Message 94824)

I noticed this WU has a long string of systems and all 8 coming back with a validate error. I just got a second one from another system. Is this something to be concerned about?

9) Message boards : Sieving : ESP/PSP/SOB sieve file has changed (Message 94820)
Posted 1800 days ago by waffleironhead
Not sure if this has to do with the change or not, but I noticed a WU with 6 validate errors.
I'm not sure how common errors like this are, but 6 separate users getting the same error is interesting enough for me to point out.

10) Message boards : Number crunching : Completed, validation inconclusive (Message 94105)
Posted 1824 days ago by waffleironhead
It means the results that have been returned do not match. One or both systems have an error. Looking at your wingman shows he has a few invalid wu, all on the same type as your inconclusive. So odds are you will be marked valid when the third unit is successfully returned.
