[Valgrind-users] Valgrind + blas and lapack

[Sami R. <sam...@un...>]

Dear valgrind users and developers,

My program uses the ATLAS version of the blas library and the clapack
library (see http://math-atlas.sourceforge.net/). blas-atlas is a linear
algebra package heavily optimized for the machine it's running on. When
I valgrind my program it crashes with:

disInstr: unhandled 2-byte opcode 0x18
This _might_ be the result of executing an MMX, SSE, SSE2 or 3DNow!
instruction.  Valgrind does not currently support such instructions. 
Sorry.

This happens when a blas function is called.

I know that there is no support in valgrind for mmx, sse and sse2
instructions. But it there still a way to detect the memory problems of
my program with valgrind ? even letting valgrind ignore these blas
functions would be good for me. If there is no way, would it be possible
sometimes in the future and if yes, when ?

Thanks, 

Sami.
