Hyper-threading configuration

Question

Suppose I have a machine, which has 2 x Intel Xeon x5550 quad-core processors (total 8 core). Hyper-threading is enabled.

I want to run an application on 4 cores (4 threads) with 2 physical cores and 2 threads per core (hyper-threading) instead of using the actual 4 physical cores.

Is this possible to do this?

Answer 1

Just make sure your application has enough threads so it can utilize enough cores. After that it is the problem of the operating system to allocate cores to your application
