[9fans] [OT] CSP in fortran ?

[Mathieu Lonjaret]

Hi all,

A bit offtopic, but since I know some HPC and/or csp pros are reading
9fans...

I have to work on a piece of fortran code to break it into pieces that
would run concurrently (à priori SPMD kind) , typically on a multicore
machine, not really on a big HPC cluster. One of the requirements is
to bring the least amount of modifications to the current code (for
maintainability).

I was hoping to find a fortran lib similar to p9p libthread, but not
much luck so far. Does anyone know of something like that?
I have started tackling it with CoArrays (http://www.co-array.org/),
and I'm going to try with MPI next. What would you guys recommend between
the two for that kind of problem?

Thanks,
Mathieu

I don't like it very much but ... have you looked at openmp? (NOT
openmpi, openmp)

Co-Array is neat. As to which to use, it's a heated argument. There
are even people who use MPI on shared memory machines so that if they
ever get a distributed memory machine the port is easier.
