The %LindaWorkers directive is used to specify computers where Linda worker processes should run. It has the following syntax:

%LindaWorkers=node1[:n1][,node2[:n2]] […]
This lists the TCP node name for each node to use. By default, one Linda worker is started on each node, but the optional value allows this to be varied. A worker is always started on the node where the job is started (the master node) whether or not it appears in the node list. %LindaWorkers may be combined with %NProcShared. In this case, one or more parallel worker processes will be run on each node (the number still determined by the values in %LindaWorkers). The value to %NProcShared specifies the number of SMP processors/cores to use on each system in the worker node list.

Do not use the obsolete %NProcLinda directive. G09 will compute the total number of Linda workers based on the %LindaWorkers input.

The following directive causes a network parallel job to be run across the specified 5 nodes. Nodes hamlet and ophelia will each run two worker processes.

%LindaWorkers=hamlet:2,ophelia:2,laertes,horatio,lear
The following directives specify that a parallel job will be executed on hosts norway, italy and spain. Nodes norway and italy will each run one 4-way SMP parallel worker, and spain will run two such workers:

%NProcShared=4   Specifies four-way SMP parallelism.
%LindaWorkers=norway,italy,spain:2
These directives make sense when norway and italy are 4 processor/core computers, and spain is an 8 processor/core computer.

Note that the %NProc directive used in earlier Gaussian versions is obsolete.
