> 512 G. OK, you have 512 GiB, and you launched 16 Ray MPI processes. If I do the maths, this gives a 32 GiB per process, assuming you don't have a swap partition and assuming that you are alone on the machine. You said that Ray is running out of memory at the place below: > Estimated remaining

Regarding the way Ray is run, soon Ray will be able to run on MPI only, MPI + pthread, or even pthread only: As you may know, Ray ships with a library called RayPlatform, which abstracts all the parallel stuff from the programmer. In Ray v2.0.0 and v2.1.0, the associated RayPlatform library (ve

Hello, You should CC the mailing list as I am sure that numerous people in the genomics community would be interested by plant genome de novo assembly ! People at McGill University did some work on plant genomes with Ray too. They posted their results on the list I think. So you have something
