got a FAX4 wu just now. is there any significant difference between this and a FAX3?

im interested to see how long this will take to complete. im still only getting about 75-80% gpu use (for longs) out of my cards with swan_sync set and 1 free hyper threaded core per gpu on all machines with gtx500 series cards. when those machines run the shorts, they seem have higher gpu use but i havent observed carefully enough to say that with 100% conviction. just informational really, its been good enough up to this point.

the FAX series gpu use is about the same as described above for longs. will be interested to see how long this FAX4 wu takes if there is a difference to the FAX3s. anything in particular to look out for?

there does seem to be some credit disparity for the FAX3 wu in terms of time vs credit rewarded but im not sure. fair enough, so long as the work keeps coming!

anyway, i definitely turned off long work units for my machines running some gtx275 cards. it was hurtin those poor, poor cards. the gtx500 series cards seem to be ok with them albeit they do take a while.

my question is this: i like running the older long wu (i.e. non FAX3 wu) on my gtx275s. they didnt have issues completing those in time. since there's no separation of long wu type on the preferences screen, would it be possible to add something like that so we can select to still run longs without FAX3? for example:

ACEMD standard
ACEMD beta
ACEMD for long runs (8-12 hours on fastest GPU)
ACEMD for long runs (8-12 hours on fastest GPU) & FAX3

or something to that effect? that way the slower cards can still get longs but not struggle with the FAX3s. just thought i'd ask. thanks for the consideration.

for this host. anyone else having the same issue? tried to see if there was another thread actively for this; sorry if i may have missed it and am asking a repeat question.

maybe my machine is messed up somehow? just got it configured last weekend perfectly, was running great until i checked it just now after work.

maybe i should just wait to see what happens?

thanks.

cool, thanks, ill keep HT on then.

...
Rob, the GTX460 works reasonably well, but last time I checked it was more akin to a GTX260 than a GTX275 in terms of performance.
...

thats ok then. i got those 460s on sale for relatively nothin, thats why i picked em up.

...
The GTX570 is still much better value for money; costs 50% less. Prices might start to change next week though.
...

totally agree: i actually bought the 570s after the 580s for just that reason.

590s out in 4 days. woohoo!

Posted 4759 days ago by alephnull
The 580's can complete some of them in 8 hr's, in fact I've had some complete in less than 5 Hr's at Stock running Speeds. But some take 10-12 Hr's even on the 580's, there's no set time for them. If you could get all the same type Wu then the Times would be more consistent but that's not the case as you get various Long Running ones.


thats interesting to know. currently im testing out a system with the 570 cards. gonna let it cook in for a month to measure a solid performance trend and then ill test out the 580s for comparison.

after reading about other card performance, it seems to make more sense to run gpu grid only on the 570 and 580 cards. interestingly, i read the 460s seem to be no good for this project (more or less the same performance as the 275s) so ill reserve that machine for my other cuda projects.

i oc almost all my cpus but all my video cards run stock speeds. maybe one day ill learn to oc them but for now, im not knowledgeable enough to oc the video cards. cpus seem relatively easier, but maybe thats cause ive been doing that for a while.

Posted 4759 days ago by alephnull
I found that the nvidia control panel wouldn't come up on my machine with a GTX295 when using 266.58. No error message. It just refused to work. It worked on other Win 7 x64 machines with different cards, just not the one with a GTX295. Ended up back with 260.99

Driver: 266.58 WHQL
OS: Win 7 x64
GPU: GTX295


i had that exact same problem when one of my machines had the gtx275 cards installed. recently they were changed to gtx570s and 266.58 drivers and the nvidia control panel now works. i was using the older drivers on that machine too when the 275s were installed. that machine was also running win 7 x64 so maybe its and issue with the 200 series cards on that os?

in my other system thats still running the 275s, the nvidia control panel works with the 266.58 drivers using xp 32 bit.

thanks for the recommendation about the cache. its been changed to 0.5 days cause that makes sense.

last night, i suspended gpugrid and when i woke up, all other cuda tasks for the other projects were done. this machine is now going to run gpugrid exclusively on the cards and CPDN on the remaining cores. interested to see its performance for the next month.

as of now, those long wu are 35 minutes @ approx 5% complete. guessin about 697 minutes (11.6 hours) but we'll see the actual time they complete. if the 580s can complete them in 8 hours, thats a huge difference. then again you mentioned long wu seem to have various execution times. maybe these are the longer of the longs.

i do have HT on on this system. would it be better to turn this off or set max cpu usage to 50%? sounds as though max cpu at 75% with HT like i have now may be ok.

btw, all my systems run 24/7. crunching and working is all i use the machines for now. sorta phased out of gaming a couple years ago as work got busier so i dont need any special configurations for that anymore.

by removing the app_info file, the four wu i had were discarded; sorry for that. i did get two new long wu so all is good. the setup seems to be good now. by tomorrow ill be able to see how fast there are able to be completed.

still got a couple milkyway, primegrid and collatz wu there to finish up before its 100% gpugrid. that should all be cleared by the end of tomorrow.

again, thanks.

Posted 4760 days ago by alephnull
didnt think about that. i was running before without the app_info.xml file and remember seeing those long work units. the only reason i created it was to play around with the cpu settings but decided to free up two cores instead. i was also considering using it to run 2 tasks per card (gpu usage only about 80% for gpugrid with 1 wu) but read that not a great idea so ill refrain from that too. seeing as though this is set in the preferences, the app_info file is no longer required so it has been removed and the project will just run normally with the preferences you helped me finalize.

btw, my cache is set for 1 day of work only.

ill monitor the project over the next couple of days and see if those long wu return without the app_info file. im pretty sure they will. thanks for the reminder that this is no longer needed and for all the other help.

cya
