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?
