Detailed Description

Simple programming environment.

MSG was the first distributed programming environment provided within SimGrid. While almost realistic, it remains quite simple (simplistic?).

Who should use this (and who shouldn't)

You should use this module if you want to study some heuristics for a given problem you don't really want to implement. If you want to use DAGs, have a look at the SimDag programming environment. If you want to get a real (but experimental) implementation of your solution, have a look at the GRAS one. If you want to study an existing MPI program, have a look at the SMPI one. If none of those programming environments fits your needs, you may consider implementing your own directly on top of SURF (but you probably want to contact us before).

MSG was the first distributed programming environment provided within SimGrid. While almost realistic, it remains quite simple (simplistic?). This describes the native to MSG.

Who should use this (and who shouldn't)

You should use MSG if you want to study some heuristics for a given problem you don't really want to implement. If you want to use the C programming language, your are in the right section. To use the Java or Ruby programming interfaces, please refer to the documentation provided in the relevant packages.
