I transfered my installation of ifort and icc from one of my workstations to another. on the new machine all works fine except for a delay in the startup of the compiler. it takes approx 7 seconds for the compiler to start doing something usefull. once started it seems to compile at the normal speed. Could this have something to do with 32/64 bit incompatibillity? or maybe something related to the license files?
some system info.

Looks as if you're using icc and not ifort. I'll move this to the C/C++ forum.

oke solved this....
ifort and icc were looking for a LM_LICENSE_FILE at a local server that I have no acces to from my other workstation.
cheers

The Intel c++ compiler works fine on AMD64 cpus, does it perform well?

There is a free non-commercial version for Linux so you might as well try it yourself if you want.
Do not expect the same level of performance on AMD because architectures are different.
