11) Message boards : Graphics cards (GPUs) : GTX 590 coming? (Message 20691)
Posted 4790 days ago by alephnull
hopefully these come out soon. i was waitin for them but when it got delayed again my patience ran out and just got the 580s. anyone have guesstimations on what the 590s may go for? i feel a second mortgage comin in the near future...

any speculation on the cpu usage for gpugrid with these cards? since they will be able to crunch 2 wu each, will that mean 2 cpu cores per card?

skgiven,

thanks for the reply. i finally was able to catch up on some stuff and make the changes you proposed. today it seemed the workday would never end...

here are the changes i made

-- bumped up the max memory usage to 90% in use / 100% not in use
-- reduced cpu cores to 6/8 (75%)
-- "suspend work if non-BOINC CPU load exceeds ..." is now set to 0
-- changed <report_results_immediately> to 1 in cc_config for now ad will keep this setting for the next month during this trial phase for gpugrid settings

you suggested "Set Boinc to "Use GPU while active"". i did not do this but i override that setting locally anyway. that way if i use another computer where this should be true and i forget to change it for that instance, ill be ok. i forget little stuff like that a lot so its more a failsafe for my spaciness.

what you said about the higher cpu usage using swan_sync is acceptable. as such, i have decided that this machine, while running gpugrid with these "school" preferences, will not run any other cuda based apps on it.

im glad the times seem to be inline with what should be expected. im interested to see how this performs over a longer period of time so im gonna let this run in this configuration for a month to see how it works out and decide from there how to set up the other systems.

looking at my app_inf.xml file, is it set up to run the longer tasks as you mentioned or would i have to add additional entries? i dont mind running those tasks but im not sure if the settings there are correct for that.

this machine still has some other project's cuda wu but ive stopped new work for those projects. when those run out, we will see the actual turnaround for gpugrid.

youre also right to remind me of that machine with the 9800 card in it. i think ill reserve that card for older, less intense cuda apps and detach gpugrid from it.

again, thanks for the response and the help. im looking forward to seeing how well these cards perform for gpugrid and will eventually migrate these settings to those other systems too.

take care.

hi.

im trying to get set up again on gpugrid. recently got a pair of gtx570 cards and was wondering if i could get some help and insight into my setup. it doesnt really seem right to me for some reason. ive read a lot of information about cc_config, app_info, windows 7 overhead, etc. and have tried various combinations of things but i still get high cpu usage and also wanted to verify how badly i may have messed things up with my current configuration. any suggestions or insight would be greatly appreciated.

cc_config.xml:

<use_all_gpus>1</use_all_gpus>
<report_results_immediately>0</report_results_immediately>

i read to set <report_results_immediately> to 1 but i was hoping i could keep this at 0 for now.

env var SWAN_SYNC = 0

i set up "school" prefs to use 87.5% cpu and set my computer to school and issued the update

locally, i have set "Use GPU Always"

this system is currently oc @ 3.6ghz. the video cards are presently running stock speeds.

ive also set my computers to be visible on the website. im currently only trying to see if i can get this one host set up properly then will add the other hosts i have:

2 x gtx 275
2 x gtx 460
2 x gtx 580

running now, gpugrid still takes 94% amd 96% on two cores for each video card. as of right now i have

wt -- (et) -- cpu% -- %complete
00:47:04 -- (00:44:40) -- 94% -- 15.2%
00:47:49 -- (00:46:26) -- 96% -- 15.3%

according to BoincTasks. the elapsed time seems awefully high @ 0.26C + 1NV i would think or am i completely off here?

im guessin that roughly equals to about 320 minutes (5.3) hours per wu. does that sound about right?

i also do not understand why two cpu cores are running close to 100%. if someone can explain this to me id greatly appreciate it.

thanks for any insight you could provide. id really like to get my other three machines crunching gpugrid again but want to make sure im not completely messing all this up.
