For Linux fortran information, have a look at:

One of my 'customers' has some code developed to run and previously succesfully tested on a Cray system in his native Sweden. We are interested in compiling and benchmarking it locally. There are several other statistical packages developed by the quantitative genetics group and written in fortran that we would also like to try out on the system once we get more proficient. The latter are written in f77 and so we could just use g77. However, the former (and some of the newer stuff from the Quantitative Genetics groups around the world) is written in F90, so I guess we will have to go commercial.

In fact, we have MPICH and a crude form of task-farming system and that's about it. I notice that some of the compilers' blurb mentions OpenMP support - only one mentions MPI specifically. I have no idea about the implications of choosing one MP architecture over another and if two can be run in parallel (irony not intended!).

One project that we are committed to trialling is one for the parent organisation (a UK Research Council) which involves a GRID-type system, utilising spare processor cycles to run sequence similarity searches (blast, basically). I suspect we will be using Condor plus some extra bits and bobs to implement that.
