 | With the recent talk about IBM and NEC multiprocessor rankings on the
"linpack scale", I was wondering how the linpack software was run on a
MP system. I had looked at a C version of Linpack, and there were no
obvious provisions for multi-processing.
Does anyone know if there is a standard way to configure linpack for MP?
If there is no standard, what does this say about the cross platform
comparisons? But that's another subject...
My basic question is: how does one configure Linpack for MP, either
generally or specifically? Can a MP compiler automatically distribute
the code among multiple processors? On the other hand, people don't
just run identical copies of the same code on each processor, do they?
Thanks for any info,
Jay

| The parallel version of Linpack is commonly known as HPL.
Optimization is complicated but I would start here:
