Two questions...

Two questions...

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

For more complete information about compiler optimizations, see our Optimization Notice.

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.

Thank you for that reply Tim, it will help me make a purchasing decsion.
