Thank you all,
In fact i was using the C compiler to compile C++ i simple didn't notice that
tha compiler was diferent... in fact i'm using the latest version of the intel
compilers!! and as Tim says "Intel recently changed to a scheme more parallel
to g++, where icpc is the Intel linux C++", and i was using icc...
Sorry for this! i hope i can compile lam now to quit using mpich :-)
regards,
nb
