Catalyst 11.11 is broken too

freighter,
While we still include the OpenCL runtime components in the graphics driver for pre-SDK 2.6 releases, SDK 2.6 features are not supported on windows xp.

Catalyst 11.11 is broken too

Thanks for info about which SDK features are supported by XP.

Seti@home apps do not use any SDK 2.6 features currently.

Back to sub-topic :

Found some freeware tool called "BlueScreenView" to decipher

bluescreens on windows XP and later. Hopefully that can help to ease bug search a little.

Catalyst 11.11 is broken too

I'm glad to report that with Catalyst 12.1 preview under Win7 x64 app produces correct results now.
Also, I have reports from testers that Cat 11.12 work OK too.
Thanks to AMD driver/support team for finally fixing this ugly issue.
Will provide data about performance with Cat 12.1 preview little later.

Micah, app was built with SDK 2.5
Why you speak about SDK 2.6 ?

Raistmer,
It was in response to raistmer/freighter. XP support is being dropped, so if issues arise, they probably won't be fixed.

Will repeat the tests after newer Win7x64 has finished install on that XP host i'm currently running tests.

Catalyst 12.1 preview performance hit

Unfortunately, not all bugs introduced after Cat 11.2 were fixed still.
Catalyst 12.1 preview shows much longer execution times than Catalyst 11.2
(same hardware, Cat 11.2 on Vista x86, Cat 12.1 preview on Win7x64).
CPU usage is low in both tests. So,that old increased CPU usage bug doesn't appear for single-GPU host now.

Is it possible to speedup total execution (elapsed) time to the level app has under Catalyst 11.2 ?

What info required to fix this issue ?

Raistmer, just a test case that shows the differences is enough.

Ok.
I just found that there is quite big dispersion of timings under Cat 11.2 with CPU busy too.

For example:

App Name Task name AR CPU time Elapsed
MB7_win_x86_SSE3_OpenCL_ATi_r390 PG0009_v7.wu 0.008955 35.974 132.818
MB7_win_x86_SSE3_OpenCL_ATi_r390 PG0009_v7_1.wu 0.008955 36.535 126.451
MB7_win_x86_SSE3_OpenCL_ATi_r390 PG0009_v7_2.wu 0.008955 36.535 126.236
MB7_win_x86_SSE3_OpenCL_ATi_r390 PG0009_v7_3.wu 0.008955 33.899 279.133
MB7_win_x86_SSE3_OpenCL_ATi_r390 PG0009_v7_4.wu 0.008955 36.582 127.559
MB7_win_x86_SSE3_OpenCL_ATi_r390 PG0009_v7_5.wu 0.008955 34.554 301.493

It's 6 successive runs of the same input data.
Look for last 2 columns for CPU and Elapsed time.
While CPU time differs not too much, elapsed time differs strong from run to run.
Will aquire some statistics under both drivers.

P.S. Interesting, lower CPU times corresponding to highly increased elapsed times.
Elapsed vary 2 fold (!)
