Re: [Getfem-users] GMM++ and Visual Studio 2008

[Cédric Venet]

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.

regards
Cédric
