Cores on a node

Hi,
I'd like to know if is possible to know the number of logical/physical
cores on a node in a cluster?

Thanks,
   F.D.

Hi!

int numCores = Runtime.getRuntime().availableProcessors();

It will return an ok value, it may not return the actual number of cores 
depending on affinity settings and things like that, but it will return 
the cores that JVM have access to.
