How to run Virtuoso on Linux Cluster

 Hi there,

I've setup 3 node Linux Beowulf Cluster in order to run Cadence Virtuoso Circuit Simulation simultaneously on 3 cluster compute nodes. Whenever, I run Virtuoso, it opens three different instances of Virtuoso interface intead of distributing three different threads across three compute nodes?

Am I missing something or Virtuoso does not support multithread architecture?

Any help would be highly appreciated.
