Hi, Its been a long time since I attempted cluster programming with Haskell. Browsing around the older and research projects suggests that they are not currently usable with recent GHC (6.5+) - be that gph or existing mpi bindings. Is anyone actively using Haskell for cluster programming and could recommend any particular set of tools? GHC's smp support within a node and binding to mpi between nodes seems the most practical way forward. Thanks, niall
