Hello, A couple of points: 1. You probably will need to compile a custom Linux kernel to support 256 cores. This isn't something that is expected to work out of the box. 2. I don't think gem5 supports more than 256 cores (and maybe not that many) without making code modifications. I believe there are a few places where we use a core bitvector, and I doubt it's bigger than 64-bits.
