I see that this requires any one of three MPI implementations -- and there are a lot of differences between these implementations internally and architecturally.
In theory, the candidate Boost.MPI should work with any MPI that meets the MPI 1.1 specification. In practice, we tend to test with those three implementations.
There's also the question of compiler compliance, and platform dependence
You'll need a modern C++ compiler to use the candidate Boost.MPI. It should be platform-agnostic, but again--we only typically test a few platforms, namely x86 Linux, x86-64 Linux, and PowerPC Mac OS X.
-- although I haven't seen the code yet, my question would be more of pragmatic in the sense that it maintain a common STL-like interface without breaking the distributed/parallel computing frame.
I would like to see really more of this -- though much like in parallel supercomputing applications, the issue really will be more of performance than anything.
Although we have yet to run the tests with the candidate Boost.MPI, we ran NetPIPE numbers using a prototype of the same C++ interface. There was no impact on either bandwidth or latency.
Anyone in the list can do a review right?
I know there are a few Boosters that are in the HPC/parallel computing area. I'm also planning to strong-arm whatever MPI experts I can find :) Doug
