Cg GPU Problem with memory

[ghriss]

Hello,

I was very interessed by Sparse Matrix Vector Product on GPU, I had found an interessing software developped by Brendan Cox (http://cml.me.berkeley.edu/~bcox/) using Cg. But, when compiling this code on Linux ( it was made for Windows at the first time ), I had the following problem at execution

reading in sparse matrix file

Finished reading in matrix file.  Starting conversion

*** glibc detected *** malloc(): memory corruption: 0x08d07d18 ***

Aborted

I understund that it was a memory allocation problem, using valgind to debug the program I found that some ones come from the libGL, but I’am not an expert of valgrind.

The code was developped for a 6800, and I use a 8800GTX 768Mo.

Is there some ones who can tests this code? :)

Thanks.
