You have expressed this problem in a very misleading fashion. Here is
a table showing the equivalent commands and options for the most
common workload managers (Slurm, LSF, PBS, SGE and LoadLeveler) that
should help:

To be honest I'm not sure about what setup was done (ex. MPI in the
background), but when I run *bsub -n 50 ./script* on our cluster, I get a
single process that has access to a total of 50 cores spread across
multiple nodes.Some of these nodes may also contain cores that are
allocated to a differe

To clarify the Linux kernel can support these sorts of systems, but
you'll either need extra supporting software or special

This is an operating system kernel issue, not a queuing system issue, so
Slurm, LSF or Torque will all have the same issue.

Josh,
I believe that -n sets the number of tasks. I only want a single task, as when
a single process uses multiple cores. srun -n 2 hostname returns
linux-slurm2
linux-slurm3
which is definitely not what I want.

Hey Mike,
I had assumed that this is what you were trying to accomplish. Seeing as
your are trying to create a single task with multiple cores, you must first
define a node that has enough cores.
As far as SLURM knows, you currently have 1 CPU core per node (as Phil
stated). SLURM is refusing to

I believe your slurm.conf is defining 4 nodes with a single logical
processor each. You are then trying to allocate two CPUs on a single node
with srun, which (according to your slurm.conf) you do not have.
You may want to consider `srun -n 2 hostname` and see where that lands you.

But, *srun -c 2 hostname* does not work, and it returns the above error.
