I should look this up but I’m lazy.
I’m familiar with MPI in Fortran/C, and IIRC they had some MPI C++ primitives a that never really got a ton of traction (that’s just the informal impression I got skimming their docs, though).
How’s MPI in C++ boost work? MPI communicates big dumb arrays best I think, so maybe they did all the plumbing work for translating Boost objects into big dumb arrays, communicating those, and then reconstructing them on the other side?
- OnlyMortal 2y agoIt’s still a dumb way to do computation. The Boost library hides the implementation away though, on Linux and Macintosh, it requires gomp. Really, it’s a wrapper but makes it “easier” for scientists to use who are, in general, not good coders. Source: I’ve seen CERN research code.
- bee_rider 2y agoWhat’s a dumb way to do computation? Using objects? I’m generally suspicious of divergence from the ideal form of computation (math, applied to a big dumb array) but C++ is quite popular.
