Re: [galaxy-dev] SLURM configuration problem

2017-03-31 Thread Marius van den Beek 
Hello Leonor,

the log you've sent indicates that you're picking up pulsar from
/usr/local/lib.
That should not happen if you're running galaxy in a virtualenv.

Apart from that you did not mention if you able to submit slurm jobs from
the command line.
That is a prerequisite for launching jobs through galaxy.

Could you post the full startup logs and job_conf.xml file somewhere?

Best,
Marius

Re: [galaxy-dev] SLURM configuration problem

2017-03-31 Thread Leonor Palmeira 
Dear all,

we are struggling with the basics in our Galaxy/SLURM configuration.

- Galaxy is installed on a virtual machine that is physically
independent from our cluster, but on a shared filesystem that is also
mounted on the Cluster

- Our Cluster is running SLURM and has 'slurm-drmaa' (Poznan version)
installed. The shared filesystem is mounted on the same mount point as
the VM, so their /paths are identical

What do we need so that the Galaxy VM is able to submit jobs to the Cluster?
Currently, running ".run.sh" from the VM as root leads to the $SGE_ROOT
error I posted in my previous email and that ends like this :

  File
"/usr/local/lib/python2.7/dist-packages/pulsar/managers/util/drmaa/__init__.py",
line 49, in __init__
DrmaaSession.session.initialize()
  File "/usr/local/lib/python2.7/dist-packages/drmaa/session.py", line
257, in initialize
py_drmaa_init(contactString)
  File "/usr/local/lib/python2.7/dist-packages/drmaa/wrappers.py", line
73, in py_drmaa_init
return _lib.drmaa_init(contact, error_buffer, sizeof(error_buffer))
  File "/usr/local/lib/python2.7/dist-packages/drmaa/errors.py", line
151, in error_check
raise _ERRORS[code - 1](error_string)
InternalException: code 1: Please set the environment variable SGE_ROOT.

Any help would be greatly appreciated.

Re: [galaxy-dev] SLURM configuration problem

2017-02-20 Thread Marius van den Beek 
It doesn't hurt to try this, but I don't think that will solve the problem.

Just to be sure, the basics are working? You can submit jobs via sbatch?
How did you compile/install slurm-drmaa ?

Also it looks like drmaa-python is being used from /usr/local/... .
Are you running galaxy in a virtualenv?
It's strongly recommended to do that.
Starting galaxy through run.sh will handle the creation and installation of
all necessary dependencies for you.
Finally it looks like you're loading pulsar from /usr/local ... this is a
bit messy.
Please try getting the cluster submission to work using run.sh first.

Re: [galaxy-dev] SLURM configuration problem

2017-02-13 Thread Leonor Palmeira 
Dear all,

we are struggling with the Galaxy documentation to understand how our VM
(with our Galaxy instance running perfectly in local) should be
configured in order to be able to submit jobs to our SLURM Cluster.

We have a shared filesystem named /home/mass/GAL between the Cluster and
the VM. Galaxy is installed in /home/mass/GAL/APP/ and 'drmaa' is
installed on the SLURM Cluster.

The following variables need to be specified but we are struggling to
find out which paths we should give them. We have currently set them
like this and this clearly does not work :

$DRMAA_LIBRARY_PATH=/var/lib/libdrmaa.so
$SGE_ROOT=/usr/lib/gridengine-drmaa (very wild guess)

We would greatly appreciate some help
Thank you in advance
Leo
