I have 6 machines and 1 control-oriented computer. Is it possible to start parallel cfx run from master node that is excluded from claster culculation?

Hi,

No. But you can give the master node a very small partition size so it only has a small computational load. I think you will find this will not be optimum, however. I bet you will find the optimum to be with partitions sized purely on the relative speed of the machines.

In this case i must have additional license for 7th machines.

The new release of CFX provides an "indirect start method" for user to execute a run on remote or batch queuing system. You may find this helpful depending on your cluster configuration. However, considering the size of your cluster, you may just want to login computing node and start job over there. Certainly, this becomes ugly once your cluster has a lot of users and nodes.

You can always launch the job on one of the six systems and monitor and control it from the 7th. The Solver Manageronly requires read/write access to the temporary run directory.

For command line options, enter 'cfx5solve -help'.
