Re: [Chicken-users] mpi egg - MPI:init error

[Ivan Raikov]

Hi Arthur,

     I use mpi for parallelizing some moderately-sized number crunching tasks (kd-tree queries over trees of size ~1e5 points. I have primarily used the scatter/gather collective operations for this. Of course, MPI is a bit low-level for a functional programming language, and one day I hope to develop some high level abstractions over the basic MPI functionality. If you have some idea what kind of concurrent patterns you want to use in your application, I can suggest which MPI functions may be of use to you.

Hello!

I'm on:
Linux Mint 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Chicken Scheme Version 4.8.0.1 (stability/4.8.0) (rev 54c391c)
linux-unix-gnu-x86-64 [ 64bit manyargs dload ptables ]
compiled 2013-01-17 on aeryn.xorinia.dim (Darwin)

libopenmpi-dev is installed and chicken-install compiled mpi perfectly.

But when I run  'csi -e "(use srfi-4 mpi) (MPI:init)"' I get exactly the same error as the one in salmonella report at http://tests.call-cc.org/master/linux/x86/2013/03/28/salmonella-report/test/mpi.html

I don't know how to make it work. Any help is appreciated.

BTW, I've got to mpi from http://wiki.call-cc.org/man/4/faq#does-chicken-support-native-threads, but I've seen it is not used by any other egg. Is it really useful to parallel programming?

Best wishes,
Arthur
