We are now testing 6.62 which should reduce substantially CPU usage. Only few WUs will have the new app for testing. If it works we will extend it. Windows XP users please report if it works, as last time we had problems.

Very good, my first WU was a 6.62 already. :D

Seems to run very well on my 9600GT. The system isn't that sluggish anymore and it is indeed CPU-recuded, after 1,5% it only has 25 seconds CPU-time. :-)
Temperature of the GPU-core is about 75°C for me, that's okay.

Thank you!

Positive here too...
CPU-usage in taskmgr under 2% (AMD X2 4200/9600GT) 3 Tasks running as expected.

Roll them bad boys out!!! :)

I have one on deck and will report if there are problems...

NOW THAT IS WHAT I AM TALKING ABOUT!

I can't even see CPU usage on the Q9300 as that task runs ... the question will be if the task runs to completion ... at the moment I only have the one task and it was the devils own to get it to run ... but ... running it is now ... sadly it is on the 9800GT so it will be most of the day (well, the time to complete is listed as 25:33:52; internal time for tasks on this machine is 48K seconds or 13 hours) before I can report on success or failure of the task execution ...

Hopefully my other machine would get one as it rummages through the stack as it would complete the task in just a few hours ...

{edit}clarified execution time{/edit}

Looks great! Only 2% CPU usage, can now handle one more free core for cpu project :)

........... Good stuff GDF - have not returned a result as of yet; but watching them work is a pleasure - 3-5% CPU utilisation on a Quad & i7.
Have an early night - go home via the pub!

P.

Have not started one on the i7 though I have two queued ... the Q9300 is 12% done with only 1:14 CPU time ... and that is with the task started at about noon (well, 19:39 UTC) sure that UCT is for this post, but that will be the delta...

{edit}

As I calculate it it is less than 2 hours ...

What seems interesting to me is that at this rate of progress the task looks to be done faster too ...

Then again, is this a different type of task that will take a different run time?

---

Ok, just started the first 6.62 task on the i7 and it is acting the same as the task on the Q9300, mostly 0 CPU, with occasional flashes to 1% ... very tolerable ...

This is the way it is supposed to work ... now, to wait till the tasks complete to see if they validate ... :)

The one on the Q9300 does look like it will run for about the same amount of time as the prior versions, as in, there does not seem to be a performance penalty for the new 6.62 version. Obviously we won't know for sure until I can get a couple done. The good news is that if past is prologue, I should have one done in 4-5 hours and the second one shortly after that ... and the third not far behind that ...

Why are we still getting only v6.61 WUs? Irritating, the CPU usage is obscene...

Why are we still getting only v6.61 WUs? Irritating, the CPU usage is obscene...

*WE* aren't ... though mostly we are ... :)

My *FIRST* 6.62 task reported as a success ...

Elapsed time was 20K seconds ... I have no idea if this is a good time or not. I rummaged a bit in the list of success tasks and if it is a longer run time it is about 3,000 seconds longer which is 50 minutes ... which sounds like a lot, but, giving up a hour to each task on the GPU is worth the release of the CPU time (at least to me) if it is indeed a consequence of the change in the application and is not just an artifact of the particular model ...

Without many more runs, no way to tell for sure ...

{edit}
With more 6.61 tasks filling up my queue I feel like a drug addict in withdrawal ...

I will point out when you make the decision to change there is a thing you can update in the scheduler that will allow all currently issued work to use the new and updated application. So, when you "throw the switch" we don't have to kill current work but can do an update and work already issued will be processed with the new application version ...

It's really strange now... I got some 6.62 tasks but one 6.61 on the same PC is still running...and...one of the new 6.62 task shows running but CPU and the task itself remains idle and NO computation is done for hours. I've tried to abort it, but with the next downloaded the problem remains, so from the 3 possible units (I have installed 1X9600 GT and 1X9800GX2) on quad core at the moment there are only 2 actually running.....

Maybe it's because there is still 6.61 unit running on the same machine..? With the 6.61 there were always 3 tasks running simultaneously..

I have aborted the pending 6.62 tasks.....and...

Ha...now I've got again one 6.61 task and at the moment with two 6.61's and one 6.62 I have 3 tasks running...

As GDF said:

I hope people with xp machines will report a go for launch! I dont like going back 6.61.

BTW, does app_info.xml works here?

OK the 6.62 unit itself runs OK...GPU time seems the same, low CPU usage, not like the 6.61 ones, but when mixed with the 6.61 there is some incompatibility..

I didn't have the chance to crunch three simultaneous 6.62 units on my machine

Hmmm, not my experience at all...

I had two 6.62 and one 6.61 in flight and now have the opposite ... of course I have the odd situation of a 295 and 280 card in the machine so have 3 tasks in flight ... might be a different story with two 295 cards ... which is what I dreamed about during my nap ...

My second 6.62 task should complete before midnight and then I am back in 6.61 hades ... sigh ... just one glimpse of the promised land ... sigh ...

that will, in theory, work anywhere ...

You going to try to cheat? :)

GDF - works and validates very well for me; so I'd be happy to continue with 6.62 WUs - actually, it is a disappointing to be starting a new 6.61 WU this morning now the test pool has gone!

With the first runs it seems to be 17% slower. On Linux the performance seems to be better. More WUs out.

I just got problems with a 9800 GX2 on Server 2003 x64 with drivers 180.48.
Two WU on errors after 10-15 minutes.

But i can't updated to the drivers 1810.20 or 181.22, because after the update i got a BSOD, and the problem seems to be also with XP x64.
SO i have to wait for new drivers.
But right now i have only 6.61 app.

Maybe i am the only one.
