I thought Julia has its own message passing paradigm which provides functionality similar to MPI but in a different way. So, I wanted to benchmark it against a native MPI implementation. If no such benchmarks exist, would it be a good idea to compare MPI and Julia performance ? After all, you would want users to use the Julia parallel computing API rather than port existing libraries to Julia ? > > On Tue, Sep 30, 2014 at 12:12 AM, Tony Kelman <[email protected] > <javascript:>> wrote: > > I'm not aware of any such data comparing Julia on large-scale parallel > tasks > > with nontrivial communication patterns vs a more conventional HPC > cluster > > approach using MPI.

Actually, I am looking at Julia for a college project and have access to a HPC cluster and am thinking to implement graph algorithms. I would appreciate if you could give me some suggestions on my idea.
