I realize that by asking this question I have already labeled myself as "unprepared" for high-performance workstations, but whatever, you have to start somewhere!
I would like to know how different linux distributions handle multiple cores and multi-threading, so as to help determine which might be best for an HPC workstation.
By default I know that Linux takes advantage of several cores, but does anybody have reference links to how it handles multi-cores (in English, i.e. I don't want to read the source code ;) ) as well as performance comparison charts (re: core utilization over time, thread distribution, compile times, etc). I understand that applications must also be optimized for multi-core support, but the first step is getting the most out of the operating system.
Or am I wrong, and is Linux inherently the same in this regards, no matter the distribution, and instead performance will be all application based?
