I just came across Random123 [1]: portable, parallel, high-quality pseudorandom number generators. It's developed by DE Shaw, but the license [2] looks to me like we should be able to make a repo for it and use it as a PetscRandom implementation. Does anyone savvier than me want to look at the license and see if I'm missing something?
