JPPF Node Service Woes
« on: August 20, 2016, 11:17:50 PM »

Hello! I am currently encountering a problem when using some old, poorly written code that makes heavy use of singletons and static non-final fields. When I ran a slave node for each core on the computer, my code would execute separately since there were 4, 8, or 16 VMs per node, each running one instance of this code. However, I transitioned to using Windows services for easier maintenance and found that slave nodes would not launch when run in a service. This seems like a bug, since the jppf.node.provisioning.startup.slaves value has no effect when running as a service, but throws no errors.
If possible, I would like to be able to use a slave node for each core, since rewriting the code would be extremely difficult due to the number of tightly coupled classes as well as accepting tasks immediately after one is finished. This increases performance non-negligibly on a 16-thread processor since certain tasks run longer than others and prevent a new batch from running.

Please disregard this post, the issue appears to be resolved without any changes! I enabled debug mode to see any errors, and all files were created and executed perfectly. Thank you for developing this wonderful piece of software!
