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?

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). |

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 ....

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. |

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.
