Welcome to your wiki! We have not really done anything with it yet, but at least there are some useful hints for using pupyMPI on MiGrid.
The manual is available at http://diku.dk/hjemmesider/studerende/bromer/pupympi/index.html
MiGrid specific hints
You should have a hostfile uploaded to your home folder if you want to run stuff on nodes (and you do want to run stuff on nodes).
Likewise you need to upload whatever pupyMPI programs you want to run. In the following we assume your program is called
hello_world.py and your hostfile is called
hostfile and that you want 4 pupyMPI processes on separate nodes.
$PUPYMPIRUN -c 4 --host-file=hostfile hello_world.py

This wiki uses the Creole syntax, and is fully compatible with the 1.0 specification.
The wiki itself is actually a hg repository, which means you can clone it, edit it locally/offline, add images or any other file type, and push it back to us. It will be live immediately.
Go ahead and try:
$ hg clone http://bitbucket.org/bromer/pupympi/wiki/
Wiki pages are normal files, with the .wiki extension. You can edit them locally, as well as creating new ones.
You can also highlight snippets of text, we use the excellent Pygments library.
Here's an example of some Python code:
def wiki_rocks(text): formatter = lambda t: "funky"+t return formatter(text)
You can check out the source of this page to see how that's done, and make sure to bookmark the vast library of Pygment lexers, we accept the 'short name' or the 'mimetype' of anything in there.
