[Caml-list] ocaml on supercomputer?

[Daniel Andor <da209@cam.ac.uk>]

Hi All,

I have some questions regarding the possibility of running large computations 
written in OCaml:
1) (Cross) compiling.  Which of mips r12000, power4 and usparcIII are best 
supported so that my existing code runs well?  How do I cross-compile (if I 
need to), given that there are math libraries (BLAS, LAPACK) that I need to 
link to on the target platform?  To run ocamlopt on the target machine, at a 
minimum I need to cross-compile ocamlrun, right?
2) Threads vs. MPI.  Writing threaded code for an SMP node would be the 
simplest way for me to harness many CPUs at the same time.  But what's thread 
support like on different platforms (listed below) with OCaml?

Basically, the three platforms I can try to target are:
Sunfire 15K (multiple SMP nodes - MPI possible), Solaris
IBM SP (multiple SMP nodes - MPI possible), AIX
Origin2000 (cache coherent shared memory), IRIX 6

What's my best bet?

Thanks,
Daniel.
