The rest of these issues (for example, when a J instance gets moved from one CPU to another) are controlled by the OS and are tunable. As for APIs... personally, on windows, I like to use sysinternals.com process explorer (it's a free download -- it works like task manager but gives you more insight into the system and greater control of the system). On a multi-CPU system, process explorer can let you inspect how a process is using the CPUs, let you set the CPU affinity (basically: whether it sticks to a CPU), and so on. There are other ways of dealing with these issues, but hopefully this will get you started. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
