multithreading - Java threads migration between dual socket processor -


i performing study related numa (non-uniform memory access) using multi-threaded code using java threads (java 8) running on dual processor: intel(r) xeon(r) cpu e5-2650 v2 @ 2.60ghz:

http://ark.intel.com/products/75269/intel-xeon-processor-e5-2650-v2-20m-cache-2_60-ghz

so in terms of computer architecture have 2 of these processors configured 2 numa nodes. been quite difficult understand threads of program mapped physical cores. in order draw conclusions need way understand if threads of program suffers of migration phenomenon between cores or between sockets during execution.

any suggestions? help.

java thread objects delegate os's thread management system, exact behavior depends on os. additionally, os not typically "map" thread core, make inefficient use of processor. can't happening in case, expect complex.
