[Archive] Multi- Processor compoputing

Message by Alessandro Colovini:
I know that SPIS supports multi thread operations, with the global preference pusherThreadNb. I’m working on a server and i’ve set that value to 8. Sadly it doesen’t seem to use 8 different CPUs, but just to repeat a cycle of high CPU usage-low CPU usage 8 times between a timestep and another.
Does someone know how to set SPIS to work on several different CPUs at the same time? (even more than 8 if needed)

Dear Alessandro,
I think it comes from your server configuration. It has to allow the Java virtual machine to use as many CPU as it wants, but this is not always the case.
