I have 5 nodes include control node.
and my nodes are looking like this
Control Node : GO1
Compute Nodes : GO[1-5]
when i trying to allocate some job to multiple nodes, only one node works.
example]
$ srun -N5 hostname
GO1
GO1
GO1
GO1
GO1
even I expected like this
$ srun -N5 hostname
GO1
GO2
GO3
GO4
GO5
What should i do?
there are some my configures.
$ scontrol show frontend
