1) Will these MKL and Lapack Libs work running Windows XP 64 bit OS and an intel (or portland group) fortran compiler?
2) Will this exploite the dual-core features of todays CPU's? How does this compare to multi threaded 2 cpu performance.
Thanks in advance
Jim

Recent versions of MKL include em64t support for Windows x64. lapack incorporates Fortran WRITEs, so it depends on the ifort run-time library. Those functions would not work with the Portland compiler library. The MKL and compiler must both be 64-bit, or both 32-bit. Either combination will run on 64-bit Windows. The full distribution of ifort 9.x includes both compilers, just as MKL does. ifort 8.1 has a separate em64t compiler, available only by download.
Generally speaking, you would get similar performance from MKL on a dual core CPU to what you see on dual single core CPUs.
