[IPython-dev] Amazon EC2 and ipython

Thanks for the update
1. What MPI implementation are you using?
-I'm using MPICH2 right now, but also have run LAM MPI on EC2...If there are
any preferences/dependencies beyond these let me know and I will add the
2. Have you tried mpi4py? At this point it blows all the other
python mpi bindings out of the water. I highly recommend it.
-No, but I can install mpi4py on the images, no problem. I've tried pypar
and have been using pyMPI because it had clean syntax, some good
documentation, and it could handle gather/scatter of numpy arrays (which was
the main thing I needed). I'm always open to switching to a better library,
and I've noticed a bunch of projects using mpi4python. What is the advantage
to mpi4py right now? Does it have better performance/ actively developed?
3. Can you make the image publicly available?
Sure thing, just let me know when there is a version of ipython1 which is
good for a release and I'll post an image to Amazon.
