new code ....

- FindSpike fully on GPU - now result  only one best spike instead whole array - removed cpu analyze loop

(for info - GPU code is now 400kb big )

Tried latest app.
Performance about the same as previous app.
Close to stock performance at some angle range values.

Placed sahcuda.exe under KWSN Knabench 1.43\Science_apps
Started Knabench-1.43.cmd
Then....
------------
Running app : default-515.exe with -nographics
with WU     : testWU-1.wu
Started at  : 02:19:54
Access is denied.
Ended at    : 02:25:50
Elapsed time: 356 seconds
Result      : stored as ref for validation.
------------
Running app : sahcuda.exe with -verbose
with WU     : testWU-1.wu
Started at  : 02:25:50

And here the fun ended with message for sahcuda.exe - Unable to Locate component:
"The application has failed to start because cufft.dll was not found. Re-installing the application may fix this problem."

I have not installed cuda 1.0 or beta 1.1 <--- do I need to do that?

Devaster please beat my guess in this post: (23. mar 2008)http://setiathome.berkeley.edu/forum_thread.php?id=35342

q:
1 Access is denied. ?
2 Do I need to install cuda
3 Anything else I'm doing wrong

Actually you need to have all needed DLLs of that CUDA runtime consist in place searchable by OS for DLL (simple saying in LIB_PATH). If you use CUDA only for SETI probably better way to put that DLLs together with exe file. When I tried CUDA few months ago the needed DLLs list was cuda.dll cudart.dll cufft.dll cutil32.dll (maybe slightly redundant).

[Devaster]

my mistake - i havent add a cufft.dll to the package.

other libraries you dont need - they are in the driver already included ...

if you wanna install  CUDA use only v.1.1 -  app is compiled with this version and cufft.dll(1.1) is about 2x speeder on CUDA devices v. 1.1 as cufft.dll from v. 1.0 ....

[Batstat]

Installed cuda beta 1.1 and sahcuda did run.
The access denied message also disapperede, dunno why.
Not sure but can it be that Knabench need boinc to run seti as a service?

As seen in Bench result file, there is some debug info witch I belive is coming from that I do not run seti as a service.

Also I got a console message '.\tools\wu_time' is not recognized as an internal or external command.

IF massive testing is needed I will suggest that a conistent howto should be written, and needed dll's should be included.

Until next time - have a nice day

bench doesnt start anything as service. It simple calls sequentally all exe files found in 2 subdirectories and logs run time for that exe. And what it does it stops boinc service at beginning and starts it at ending of test.

Also I got a console message '.\tools\wu_time' is not recognized as an internal or external command.

When I checked my PC with antiviruses one of them suspected this tool. Maybe your antivirus blocks its execution too? Anyway wu_time.exe is not needed for main objective of bench - to log execution times. So you could just delete the exe and ignore all errors that arise from that.

[Devaster]

new code (cufft.dll v1.1 included)...


- PowerSpectrum transpose moved to the GPU ....
- eliminated one GPU to CPU memory transfer ....

Thx Raistmer I will check it out, or just as you suggest ignore it

As Raistmer indicate, yes my AVG do tell that wu_time.exe is infected with worm/Sohanad.F and from that AVG decide to block access to the file.

I updated my GPU bios from last time. Test result from last app for Devaster attached.
