What is the optimum cost effective Intel processor / motherboard to get good MKL performance for level III blas cgemm for matrix sizes in the range of 500 x 500?
Am quite confused as to relative merits of single / dual core, Pentium vs Xenon, 32 vs 64 bit, HT on / off, cache size, etc. for MKL blas 3 performance.
Hardware costs should stay below $4k. The app is LU factoring100,000 unknowns block wise which will also require fast disk IO, thus a MB with SATA II / Raid 0 will be required.
This will be a Fortran 95 (CVF or IVF)code under Win XP.
