The question is whether ESSL or Parallel-ESSL is needed to do true parallel computing on a Quad-core chip? Basically I would like to know if anyone is working on making a Quad-core CPU parallel (preferably f77 or f99) under RedHat LINUX? If I install RedHat LINUX on a Quad-core CPU (thus avoiding a high speed switch) what would be needed to run parallel f77, a new compiler?
The Intel "Math Kernel LIbrary" (which includes BLAS and a lot of other goodies) http://www.intel.com/cd/software/products/asmo-na/eng/ 307757.htm has many routines which are internally parallelized for multi-core machines.
So, if you're using BLAS you should be able just to link against these and get a benefit which depends on how much of your execution time was spent in the library routines.
The Intel compilers also include an auto-par switch, so there's some chance that recompiling with that might help too, and, of course also include OpenMP support.
(Disclaimer: I work for Intel, and haven't used MKL or auto-par myself, so as ever YMMV)
