Hi
keep getting messages like "ATI GPU R600 (R38xx) does not support OpenCL

according to the spec of the Fury X they support
open GL 4.5
Open CL 2.0
DX 12
Shader Model 5

Does anyone have any info
Cheers

What setting do you have in the app_info.xml ?

I just put 2x 5970 in a machine and am only able to run with <coproc>1</coproc>
as when I set it to 0.5 it stalls and sloooooooooows right down. Is this the throttling you were mentioning in your post?

I'll try 0.5 with the bridge on and see if that frees mine up but I am still interesting in your app_info settings.

Thanks ! :)

EDIT:

So it seems I cannot run more than 1 MW task per GPU. This is down from 2 per GPU on the 4850x2 that were in there. So i have gone from 8 concurrent tasks to 4. Now each task should be alot faster so I guess I will have to see after 24 hours how its playing out but right now my hourly RAC is the same as it was with the 2x 4850x2 with 2x 5970.


I have 1 ATI 5970 crunching MW for about 20 hrs so far. only 2 WUs @ time in 1.40mins Temp only 78 degree C
Also have 1 4870x2 doing MW 2WUs per 3.13 mins.
so the ATI 5970 is more than twice the speed of a 4870x2.
May double up the 5970 in the future as that box has a 1000 watt PSU, Speedo case.

Hi guys
Why is the server not able to open the database?
I have 100 WUs waiting
server seems fine but someone is not looking at whats going on.

finally got it going on vista 64 after downloading the new driver
Does it need cuda 2.3?
aver crunch time is 6.5 mins 2 apps running a a time
at the moment very poor perforance compared to ATI cards but early days I suppose.
My 2 4870x2 are turning in 300k credits or more a day

It seems to always be on the weekend when something screwey has to happen. Nobody around to fix things for a few days.
I'm begining to think the staff starts their weekend celebration a wee bit early and does stuff like this to us just for giggles.;-)

Hi
What has happened too the WUs ?
Only getting one or two per hour for the last 12 hrs.
last week we where getting 74 credits per WUnit , now only 37. why the differatance?
I normally can crunch 300k credits per day , now 10 to 12k if I am lucky.

interested in your post
I have 1 4870 x2 and would like to go to 2 but have had seriuos problems.
I am running Vista ulimate 64 on a i7 920
By 1 4870x2 is happily doing 7000 credits and hour but had huge problems when i put 2 in the box.
so if you can sort it out PLEASE send me some info.
Thanks

I'm curious about some of the code in the app_info_xml

<flops>1.0e11</flops>
<avg_ncpus>0.1</avg_ncpus>
<max_ncpus>1</max_ncpus>


i assume flops means its capped @ 1 and the cpu thing is that 1 chip or how does that work with quad cores?

the other thing if you have 2 4870 x2's would that be like 4 gpu so you could do like 2 wu per gpu?

we have a few guys from places round the world who are curious.

Im really curious how all this works or if there are changes i can make to get mine doing more.

100,000 pionts per day is not enough


I have tried 2 4870 x2 and its more trouble than its worth.
Using my i7 920 with one 4870 x2 doing 7 climatepredection WUs and using Gispel 19f code I am also able to do 6 MW WUs as well . no problems no hicups.
at the moment averging 7000 credits per hour 170000 credits a day.
I find its very important to do 2 applications and get a balance between CPU based apps and the GPU MWs . about 18 tasks at once , if more it wastes processing time.

interesting how differed WUs clash
I have been running 7 climateprediction WUs and 6 MilkWay WUs at once for the last 2 days. have been getting 120000 to 140000 credts a day.
By decrasing the resources for MW WUs to 12% seems to keep everything in sync.
Always have plenty of WUs and minimal overflow, 18 tasks at a time.
thinking of getting a another 4870x2, should double my work.
still using BOINC 6.6.36

well 2 days and 120000 to 150000 credits a day later
I have changed to climatepredection 6 WUs running and 6 MW running at the same time
12 to 15% resources for MW and the rest to 1 Ap Climatepredecition
avering 6000 to 7000 credits per hour run.
find it best to leave Boinc Manager alone.
haven't worried about debts or changing scripts as yet.

so far so good .
Yes I changed to Catalyst 9.5 on advice from others. am using a ATI 4870 x2
today will be the first day on the 12% MW and the rest to WCGID.
while I still getting some overflow at least I get plenty of WUs
approx 1200000 credits for the day and I have not had to touch the computer
will try the edit of the app info file if I have problems down the track.
also using BOINC 6.6.3

I have follying your posts re BOINC issues.
the i7s need good control.
I have been having the same issue of to many WUS going at the same time, up to 42 on my i7, with only 6 MW moving.
Previously had resource allocated 66% MW and 34% WCGrid
have now got 11% for MW and the rest to other apps.
overflow ploblems have reduced greatly . incoming WUs stay as "waiting to start" instead of running in space.
will leave running over night and see what happens.

I have the same problem as you PoorBoy but on my
i7\4870 box the whole computer stop running and I have to reboot
to regain contol.

This happend even when I under clock my 4870 card to 500\700 and
have the side open on my box so the problem should not be heat related.

I wonder if it is caused by some of the wu's or if BOINC is the
caus of the problem.


I have come to the conclusion that it does't mater how running but not running happens.
Exiting BIOMIC Manger will stop the counting but not fix the problem.
I still have 5 WUs going and about 20 counting.
Don't know if it ties up resources!
Hope some smart programmer some where can suggest a solution
I find that if I only run MW apps the system overloads and progreess of WUs grind down.
If I could make the software only take on 5 WUs at a time it would be great . All done in 2 mins , then move on to the next 5
looking seriously into doing Climate predication on 7 threads leaving 1 thread to do 5 MW WUs at a time
apart from that no crashes of system but I do Reboot eery day .
i7 920 oc to 3.4 6 gig of 1600 dr3 Ram and 2 300 GIG Raptors in raid 0 plus
1 Terbit back up

Well just over a day and 60k cridts later
only problem is when more than 6 WUs run @ a time They count as going but don't
I am getting 50 at a time now so thats not a problem.
some time the system does go haywire and WUs have to be suspended
once i have used up all these WCG WUS i may go to climate predication , rn 7 threads and leave 1 thread to do MWs
will try editing that file if i get into trouble. will try to restrict to ^ WUs at a time

getting 10 to 12 WUs every 15 mins now
how do you allocate 1 core to MW so only 2 WUs get done at a time?
they then get done in less than 2 mins and reduces temp GPU and CPU
I have had to slow GPU down as was getting over heated.

finally it is going
most WUs take 2 to 3 mins, up to 10 WUs running at one time.
problem will be the server keeping up
