Is Knime optimized for multiple sockets/ NUMA systems?

KNIME Analytics Platform

Hello,

When running a parallel chunk loop in Knime on a NUMA system is there a chance the sub processes will be scheduled on multiple NUMA nodes and use memory from different nodes at the same time, thus creating inefficiencies?

If yes, would adding -XXUseNuma to .ini or setting up affinity in windows be a potential solution?

Thanks

Nicolas

In Java you have almost no control over memory management. Everything is transparently done by the JVM. Setting this option may help in this case.
