At my company, our simulations are written in a combination of c#, c++, and assembly. Yes, there is assembly in there. We divide our simulations into “chunks” which is usually around 10-100 simulations. Each chunk gets its own seed. The scheduler we use is dynamic like the one in Julia and by having each chuck get its own seed we get reproducibility no matter if we are running on any number of cores. 1 core will produce the same results as 6 cores.
I am currently trying to do the same with Julia. Re-seeding the MT algorithm is very expensive time wise. Right now it is faster to keep my algorithm single threaded.
For me, this is a killer feature.
