i think the stuck state you're interpreting is a misrepresentation<br>
that HPC is full of stodgy greybeards who only want to run MPI code<br>
written in 1970's fortran. i don't think that's the case anymore.<br>
HPC has branched out and includes a lot of ancillary paths, but it<br>
still holds onto its heritage, which is something I appreciate. HPC<br>
has never been about flash, it's about solving the world's hardest<br>
problems. You don't always need a porsche, sometimes a yugo works<br>
just as well<u></u><u></u></p>
