hi,
try to define _SCL_SECURE=0 (warning ABI incompatible so all the code
you link must use this flag)
for code using the stl heavily, it can result in 100x speedup.
perhaps also:
#pragma inline_recursion
#pragma inline_depth
and check all the optimisation are on.

Hi,
I have recently ported our code written with GMM++ to 64-bit
system
and recompiled the code in Visual Studio 2008. The weird
thing is
that when I run the code, GMM++ function compiled with Visual
Studio
2008 has extremely poor performance comparing to the old
32-bit code
compiled with MingW on Windows. I also compiled the code with
Intel
C++ Compiler 11.1 in Visual Studio 2008, and the performance
of
GMM++ functions were still very very low and they worked very
slow.
What is the reason? I thought, maybe the GMM++ code is suited
to be
compiled with gcc, but in the web site it is stated that the
code is
compatible with Intel C++ Compiler 8.0. Has anybody had same
experience?
Thanks,
D.
