Yeah, I support these people regularly. If you can replace "for" with "parfor" and it just goes faster, well, God bless you. In my experience, 90% of these novices haven't the faintest clue of what's going on. "It worked before, but now I'm running out of memory." "Why are you telling me that I'm crushing disk I/O?" "I went from 1 core to 40, and now it runs slower!" "I requested 32 nodes--why doesn't it run 32x faster?" "I requested one core, but MATLAB saw the awesome stuff in /proc/cpuinfo and ran 40 cores. Why is it even slower than ever?" Bless the clueless, for they shall inherit the earth. (But please, don't let them write coronavirus models in public...)
