I am assuming the sbin and srun you mention come from Slurm. This
documentation [1] for MPICH2 with Slurm suggests that you really
should build it against your Slurm installation. Towards the end,
however, it includes an example that *may* work for launching the
current ParaView linux binaries with Slurm using:

salloc -N 2 mpiexec my_application

It could looks like it would be fast to try out if you want to give it
a shot. Just sub out "my_application" with "pvserver".
