Q: When I run the parallel Linux version, only one node is used as client for the calculations.
A:
If you do not run the calculations from a queuing system like PBS or DQS, the Turbomole scripts do not read in the MPICH hostname file machines.LINUX - an own file containing the hostname of the machine you have started the calculation from is generated.
You can set the environment variable HOSTS_FILE to a file that contains a list of nodes.
