============
Yes BW supports CPU Processor Affinity. Refer to  TIBCO BW Administration Guide --> Chapter 9 :Performance Tunning:
=============================.
Processor Affinity
On a multi-CPU machine, process(es) can be configured to run only on a dedicated set of CPUs using processor affinity. Processor affinity takes advantage of the fact that some remnants of a process may remain in one processor's state (in particular, in its cache) from the last time the process ran. Scheduling it to run on the same processor the next time could result in the process running more efficiently than if it were to run on another processor.
=============================.

CPU Processor affinity is controlled at the OS level. There is no configurable property in BW. Check your OS to find the setting for  Processor Affinity.


Environment:
============
TIBCO ActiveMatrix BusinessWorks(TM) 5.10.x.
TIBCO Runtime Agent(TM)5.7.x.
Operating System: All.


Resolution:
===========
CPU Processor  affinity parameter is configurable at OS level for example :

Windows 7: You can refer to the following tutorial where you can set affinity from Task Manager or you can set affinity while running the exe from the command prompt"  http://www.techrepublic.com/blog/window-on-windows/change-the-processor-affinity-setting-in-windows-7-to-gain-a-performance-edge/5322.

Linux : There is taskset option. Refer to http://linux.die.net/man/1/taskset for more details or check with your OS User Manual.

For Other TIBCO supported OS Platforms,check  their respective manual or help to find the correct options to set CPU/Processor Affinity on HP/Solaris/IBM platforms.
