MPI status?

[Phil Trinder]

Duncan,

The latest version of GpH is based on GHC 4.06 and runs on Linux PCs. A release 
based on GHC 5.01 is imminent. In the next couple of months we plan ports to 
Sun Solaris, and later to SGI Origins.

GpH is bundled with many GHC versions - details at 
http://www.cee.hw.ac.uk/~dsg/gph/, and requires PVM rather than MPI. However, 
as Manuel Chakravarty points out, even with gcc on the T3E it's non-trivial to 
port GHC.
