1) Message boards : Number crunching : Time to run a PPS Sieve on my CUDA went from an average of ... (Message 149670)
Posted 177 days ago by Profile Ghery Pettit
Fun and games. In December the laptop quit. So I contacted HP and sent it in. Came back dead. Sent it again. Came back dead. Sent it in a third time with a strongly worded message. . I got an email in early January saying it would be back in a few days. That few days stretched into a few weeks. I finally got it back and it has been running fine. Except - the sieve job that used to take about 1/2 hour is now taking a touch over 2 hours. Temperature does not appear to be an issue this time. And the charger has no trouble keeping up. This is really frustrating. I'm on the verge of saying to heck with it. Any ideas short of saying to heck with it?
2) Message boards : Number crunching : valid but no credit, yet (Message 140989)

Check the WUs and see if your wingman has completed them. It not, that's the holdup.
3) Message boards : Number crunching : many PPSsieve units are pending? (Message 140559)

In case you weren't aware, the number of pending tasks is entirely dependent upon what other users are doing. High or low pending numbers have nothing to do with what's happening on the server.


Yes, but 25 just today (UTC) waiting for validation (35 total) is much higher than normal. So, how is the server?

Looks like they are pending again.


Indeed, they are. A whole bunch of them. And it has been going on for over a day. Not just a slowdown.

about 1800 seconds to about 6300 seconds. No change in processor, just the time required to process one went up dramatically last night. Any ideas why?

Seeing as your runtimes have not dropped after running many tasks, I must ask you: have you tried turning it off and on again?

Besides restarting your computer, is there anything else you've started running on your computer? For example, did you start running SGS? It looks to me you started running SGS around the same time your PPS Sieve tasks got longer. It looks to me you're pushing the laptop too hard and it can't cool itself properly, and as a consequence, it had to run the GPU at a lower speed to keep it from thermal throttling.


Sorry to take so long getting back to you. Heat does appear to be the main issue here. I've propped up the back of the laptop to improve air flow, so we'll see what that does. I've got the run time back down to "normal", so we'll see what happens. It is interesting to note as well that on occasion the battery charge cannot keep up. Not always, but now and then. I get the feeling that HP really didn't design this laptop to be a full time cruncher. Oh well.

7) Message boards : Number crunching : What happened in the last 10 days or so? (Message 108038)

The aborted tasks are the longer ones. I aborted them in advance as I know this computer is SLOW and tasks scheduled to run 90 days just aren't worth the time. Once I figure out how to not get such long ones I will happily delete them. However, this sudden dive in RAC is caused by something unknown. I've been aborting long ones for quite some time (months).

About 10 days ago my daily credits went from all over the map (which I would expect) to around 1500-1700 a day. I haven't changed a thing on the machine I'm using for running PrimeGrid. At least, nothing that I know of. Looking at BoincStats I see where my world ranking based on RAC is dropping, so it looks like this isn't a problem confined to me. Any ideas?
9) Message boards : Number crunching : Task limits being reduced (Message 87574)

The event log only has entries for today, so if offers no clues. My other machine, older and running Windows XP, is doing fine, so I'll see what happens on this box over the next day or so.

Thanks.

I don't know if this change is the cause, but I now have NO jobs for Primegrid on the machine. What happened? SETI is still running on the GPU.
