I wonder if there are some driver compatibility problems with CUDA 2.0.
My graphics card is 8800 GTX and I have been using CUDA 2.0 beta on the driver 177.35. (in XP)
I have written my code which runs well with the 177.35 driver, and found that there are updates of a driver and CUDA yesterday.
After I updated the device driver to 178.28 (and I also tried 180.60 available in the CUDA download page), the code I wrote does not run well.
It gives “unspecified launch failure” error (I think it comes from the cudaMemcpy2DToArray statement.) and many other messages like
“First-chance exception at 0x7c812a5b in tracker_debug.exe: Microsoft C++ exception: cudaError_enum at memory location” when I run it in Debug mode.
When I roll the driver back to 177.35, it runs well again. Thus, I wonder this is the driver compatibility problem.
Is there anybody who has or solves the same problem?
I dug this forum for a while but I can not find any post about this.
Any comment or idea is welcome.
