Hi Fred, For us, PBS (free) is installed to a shared filesystem that is mounted via NFS to the galaxy server (and via GPFS to the rest of the HPC). The server home directory is also custom (/opt) but local to the disk on each HPC node (including galaxy).
I have tested running a simple PBS script from the galaxy node as the galaxy user and it was able to run successfully. In your case, have you installed PBS Pro with all default installations paths? It seems to me that the pbs-python module is happy to be installed with PBS defaults but has trouble with a custom PBS install. I am having to look into the pbs-python installer script to hunt down the relevant variables. Re: parse error – I had configured a basic job_conf.xml to test with galaxy, but it seems it was too basic. Are you perchance able to provide an example of your job_conf.xml for reference?

I never had any problem with pbs-python however. Here, for us, the PBS client is installed locally (on the VM that hosts Galaxy). Are you sure that PBS is well installed ? Are you able to launch a simple PBS script with the galaxy user ? Maybe the error you see (xml.etree.ElementTree.ParseError ) is because one XML config file has an issue.

PBS is installed to a custom location on a shared filesystem mounted via NFS to our galaxy server, however, installing pbs-python using the git clone / python venv method in the documentation fails because it can't find PBS and there does not appear to be any way to define it for pbs-python (I could be wrong?). ... gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -fPIC -DTORQUE_4 -I/usr/include/torque -Isrc/C++ -I/usr/include/python2.7 -c src/C++/pbs_wrap.cxx -o build/temp.linux-x86_64-2.7/src/C++/pbs_wrap.o In file included from src/C++/pbs_wrap.cxx:2978:0: src/C++/pbs_ifl.h:90:32: fatal error: u_hash_map_structs.h: No such file or directory #include "u_hash_map_structs.h" ^ compilation terminated. error: command 'gcc' failed with exit status 1 So I went ahead and installed pbs_python from source (which does allow you define a PBS_PYTHON_INCLUDEDIR environment variable), however, galaxy does not seem to like this as evidenced by errors during startup. I suspect this has to do with pbs_python not being installed into the galaxy virtual environment. galaxy[97486]: Traceback (most recent call last): galaxy[97486]: File "<string>", line 1, in <module> galaxy[97486]: File "/hpc/software/installed/galaxy/19.05/lib/galaxy/dependencies/__init__.py", line 179, in optional galaxy[97486]: conditional = ConditionalDependencies(config_file) galaxy[97486]: File "/hpc/software/installed/galaxy/19.05/lib/galaxy/dependencies/__init__.py", line 32, in __init__ galaxy[97486]: self.parse_configs() galaxy[97486]: File "/hpc/software/installed/galaxy/19.05/lib/galaxy/dependencies/__init__.py", line 41, in parse_configs galaxy[97486]: for plugin in ElementTree.parse(job_conf_xml).find('plugins').findall('plugin'): galaxy[97486]: File "/usr/lib64/python2.7/xml/etree/ElementTree.py", line 1182, in parse galaxy[97486]: tree.parse(source, parser) galaxy[97486]: File "/usr/lib64/python2.7/xml/etree/ElementTree.py", line 656, in parse galaxy[97486]: parser.feed(data) galaxy[97486]: File "/usr/lib64/python2.7/xml/etree/ElementTree.py", line 1642, in feed galaxy[97486]: self._raiseerror(v) galaxy[97486]: File "/usr/lib64/python2.7/xml/etree/ElementTree.py", line 1506, in _raiseerror galaxy[97486]: raise err galaxy[97486]: xml.etree.ElementTree.ParseError: junk after document element: line 4, column 0 I've attempted reinstalls of the git clone / python venv method with the PBS environment variable to no avail. I was wondering if someone might have any ideas about working around this roadblock, or may have encountered a similar module installation issue in the past? Also, I was hoping to get some ideas/examples of generic job_conf.xml definitions for PBS clusters? Things like best practices, caveats, etc. My understanding is that, unless configured otherwise, galaxy will submit jobs as the galaxy user and that configuring the server to run jobs as end users themselves is difficult/risky. Just wondering if you guys might have opinions/thoughts/recommendations about this? And finally, what would be a good way to test that galaxy is submitting jobs to the queue properly? Is there some generic test data/procedure to verify that the galaxy instance is working as expected?
