I agree with this, but it also sort of risks being a self-fulfilling prophesy; everyone uses MPI because everyone uses MPI, and no one uses Chapel yet because no one uses Chapel ye…

Chapel has been used for incompressible moving-grid fluid dynamics, so it's certainly feasible. For that problem the result was ~33% the lines of code of the MPI version. There is …

Comment #9337271
I agree that languages that rely on tracing GC seem like they're fundamentally at a disadvantage when it comes to pushing the envelope of single-node performance; the best article …

I think with GPGPU, the issue is a little different; it's local computation, so a bit orthogonal to distributed-memory coordination. But it is interesting to see how many higher-le…

Oh, sure. I don't think anyone should start rewriting old codes; but as new projects start, I think we have a lot more options out there than we did 10 years ago, and it's worth lo…

Thanks! I'm probably mischaracterizing Charm++ a bit, because I'm most familiar with it in particle context (OpenAtom, ChaNGa, NAMD). I guess it's probably particularly used in tha…

I think coarrays have a lot of promise; it's less ambitious than the single unified picture of a program that Chapel or UPC has, but maybe that's a feature, not a bug, for incremen…

Certainly Prof Hoefler has done a lot of work driving the design of updated remote-memory access for of MPI-3, and any further progress would be welcomed; but I don't think any mod…
