cudaError_enum memory Problem

Postby merhof » Tue Oct 12, 2010 6:51 am


I just downloaded CULA and tried to get the examples to work. As it seems there is an Memory related error, that i can't fix or understand properly.

When e.g. compile the gesvd_vc8 example, all dll's are loaded correctly and the 2 images are created, but with the same size, shouldn't be the 2nd image be compressed?

Visual Studio 2008 which I use, shows a lot of error lines with memory-position errors, eg:

An Exception (first chance) at 0x755e9617 in gesvd.exe: Microsoft C++-Exception: cudaError_enum at memory-position0x0012fa48..
Eine Ausnahme (erste Chance) bei 0x755e9617 in gesvd.exe: Microsoft C++-Ausnahme: cudaError_enum an Speicherposition 0x0012fa48..

The other examples produce similar errors pointing to memory positions. Does this have to do with my CUDA Drivers (CUDA 3.1), my GPU, or what am I doing wrong?

Thanks in advance!

Try running outside the MSVC debugger and/or turning off breaking on first chance exceptions. CULA uses exceptions internally, but will always handle them before returning to the user. Your debugger appears to be catching them before giving us a chance to handle them (that's what first chance means.) Chances are there there is no true error here.
