Hi,

can anybody share experience with OCaml on an Blue Gene ?

I may have the opportunity to use one here at EPFL, and I was wondering if somebody has already managed to compile OCaml on that IBM thingy.
I've been told everything is cross-compiled, so I don't expect too much trouble...
On the parallelization side, everything runs with MPI, so there too things should in principle go allright.
It should however require quite a bit of manual Makefile editing (they have highly customized C compilers), so I'd be glad to receive feedback on that.

thanks!

Guillaume.

Many years ago, I ported to ocaml bytecode interpreter to some sort of Cray (I forgot the details). That was quite simple (IIRC, just some #ifdef to add somewhere). According to http://en.wikipedia.org/wiki/Blue_Gene each processor is a PowerPC variant. Since PowerPC is supported by Ocaml (I don't know if it is the old 32 bits variant or the 64 bits one), I could imagine that even the native compiler could run on it, and I guess the difference between Blue Gene and other PowerPC (perhaps AIX machines) is mostly minor operating system things. But as usual, the evil is in the details. I just hope your port will be available to others, just in case. Good luck.
