Another (slightly more heavy-weight) option would be to use something like hMPI (http://www-i2.informatik.rwth-aachen.de/~michaelw/hmpi.html). It doesn't work as per the web page on ghc 5.04; however, bringing it up to date isn't very difficult and I have done it myself so I could give you the updated source files. - Hal -- Hal Daume III "Computer science is no more about computers | hdaume@isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume On 15 Oct 2002, Jan Kybic wrote:
Hello, I would like to parallelize my program in Haskell but I have difficulties getting started. I would therefore appreciate any help or pointers.
I am using ghc-5.04 on i386 Linux. I installed from a binary bundle on the ghc website. I thought I would just compile with --parallel and I would get acess to the 'par' primitive. But no, it seems that the parallel libraries are missing on my system. If I understood correctly, they are files with _mp in their name, right? I looked on the web for a precompiled binary version of those libraries, in vain. I found the GUM web page but it seems to be much outdated, based on the ghc-4.06. Is there any more recent version available?
Then, I tried to get the ghc-5.04.1 source distribution and compile it from source. I found the building guide on the ghc site but it talks only about fptools in general and does not mention the ghc specificities. The build (./configure --prefix=$HOME ; make) fails. First of all it could not find 'readline', which I solved by some config.mk hacking, now it fails with: Main.hs: can't locate import `Exception' apparently because the binary bundle directory hierarchy is different from what the Makefile expects.
I also tried to build only the libraries. It first failed with not being able to find the ghc-pkg-inplace, after changing this to the installed version it fails with Reason: No such file or directory File: ../../ghc/driver/package.conf
Any help appreciated. Thanks,
Jan
