I'm in the progress setting up multiple nodes in one box, using this article as a reference. A couple of doubts:
- number of cores, Does this refer to physical cores or cores including hyper-threading? With hyper-threading, my machine has 32 cores (nproc shows 32), but it only have 16 physical cores in fact.
- referring to the file descriptors and mmap file limits, e.g for open fie descriptors, for one node, we set to 64k, do I need to set this to 64K * n? n is the number of nodes to be installed on the box.
Thanks in advance!
