Hello  
I’ve got some issues when running pvserver on HPC(Slurm) by singularity. Looking for some help sincerely.

**Version**  
[ParaView-5.11.0-MPI-Linux-Python3.9-x86\_64.tar.gz](https://www.paraview.org/paraview-downloads/download.php?submit=Download&version=v5.11&type=binary&os=Linux&downloadFile=ParaView-5.11.0-MPI-Linux-Python3.9-x86_64.tar.gz) (download from this link)

**Run Env**  
HPC Cluster managed by Slurm (CentOS 7) without any mpi

**Question**  
I packet paraview to singularity SIF.

Dockerfile like

```auto
FROM centos:7

COPY paraview /usr/local/paraview

RUN yum install -y libXcursor mesa-libGL libgomp

```

run docker build to image

```auto
docker build . -t paraview-dev:test01

```

Then turn docker image to singularity sif

```auto
singularity build paraview.sif paraview.def

```

paraview.def

```auto
# paraview-5-11.def
BootStrap: docker
From: paraview-dev:test01

%labels
    Version ParaView 5.11

%setup

%files

%environment

%runscript

exec $@

%post

```

sbatch script1

```auto
#!/bin/bash

#SBATCH -N 2

singularity run -e /data/wanghao/paraview.sif /usr/local/paraview/bin/mpiexec --hosts c1,c2 -np 2 /usr/local/paraview/bin/pvserver

```

sbatch script1 output calls error like below

```auto
bash: /usr/local/paraview/bin/hydra_pmi_proxy: No such file or directory

```

maybe I should not `singularity run mpiexec -n 2 pvserver`? Then I try to edit sbatch script2 like `mpiexec singularity -n 2 pvserver`  
sbatch script2

```auto
#!/bin/bash

#SBATCH -N 2

# /data/wanghao/paraview/bin/mpiexec is the same with mpiexec in singularity sif file (/usr/local/paraview/bin/mpiexec)
/data/wanghao/paraview/bin/mpiexec --hosts c1,c2 -np 2 singularity run -e /data/wanghao/paraview.sif /usr/local/paraview/bin/pvserver

```

The Slurm output is

```auto
[root@c1 data]# cat slurm-37.out 
Waiting for client...
Connection URL: cs://c1:11111
Accepting connection(s): c1:11111
Waiting for client...
Connection URL: cs://c2:11111
Accepting connection(s): c2:11111

```

It seems launch two rank 0 mpi process by pvserver?

**What I want**  
I want run pvserver in singularity and run it by mpi and slurm to do a multiple node job.  
Hope to get a reply, thank you again！
