Re: [NMusers] Turning off IEEE floating point messages for new gfortran compilers

Bob,
Do you (or anybody on the network?) have any information on comparison
of different Intel Fortran compilers for Nonmem use (computational part,
not compiler time), specifically, between the most recent one (14?) and
version 11. Is any other compiler faster than Intel on Intel Windows
machines?
Thanks
Leonid
