ACML-GPU with NO_GPU=T

strange dgemm behavior

Hi,

I found that on my system ACML-GPU's dgemm behaves strangely when NO_GPU environmental variable is set to T.  Above some matrices' size threshold, dgemm results differ from both naive matrix multiplication implementation and ACML-GPU's dgemm with NO_GPU != T. I work on Ubuntu 9.10 64-bit, kernel 2.6.28-16, Catalyst 9.10 (or 9.11). gcc used to compile tests is custom-built 4.1.2. Can you confirm it's an ACML-GPU issue? Or perhaps I just miscompiled it somehow.
