I work on a solution based on JPPF and the only time it ever even gets thought about is when I get the email about a new version. Its nice having a system that just runs and doesn't need constant tweaking. The little install I have can grow between 2 to 256 vmachines (x that by 4 for nodes) dynamically when needed. Short processes are minutes while long processes can be weeks to a month. I quit counting bandwidth on the pipes, big numbers become cartoonish to our pathetic tiny little brains.
So, JPPF is at 3.0! Good to hear! I will rolling it out as soon as possible.
