Hi Carlos, sorry for the slow reply. With a small 10 user setup (I assume just one group) your installation is probably going to be a lot less complex than ours. We are running services for users from multiple labs and departments, so a chief concern was making sure private datasets always stay private - which is relatively involved when using Galaxy to run jobs on a general-purpose shared cluster.
I think if I had to recommend picking a job scheduler I would suggest SLURM since it's probably the most 'fashionable' choice at present. You also have the advantage that SLURM is used with Galaxy in the Galaxy docker image etc. which ensures people notice if the Galaxy->DRMAA->SLURM setup isn't working. I've also used Galaxy with GridEngine in the past, and that was fine - but is becoming a less common choice as a scheduler. Having said that, I don't think that the job scheduler needs to be your biggest concern. I would focus most on the file system and user account setup you are going to need. * How are you going to migrate from standalone Galaxy to a situation where your new cluster can see the Galaxy data files, tools etc. Are you purchasing storage with the cluster? If so do you move Galaxy onto that storage, or can you mount existing Galaxy data onto the cluster nodes? If you can do that, is your networking such that performance is sufficient for the type of analysis you are going to run? * Do you need to, or will you need to, keep track of per-user usage of the cluster for things that Galaxy will be running? If not then you can just have a galaxy user on your cluster and things are pretty easy for file permissions etc. If you need to track jobs per-user then it becomes more complex, and the solution depends on how much privacy you need for datasets, how your cluster will authenticate users etc. The filesystem and user accounts issues are, in my mind, the ones to focus on. You can always modify Galaxy's config to switch to a different job scheduler fairly easily. You cannot as easily move around large amounts of data, and reconcile local vs cluster user accounts, should that be necessary.

Hello David, Thank you for the great feedback. We are at Hunter College in NYC, part of the City University of New York. We recently ordered the cluster which comes with Bright Cluster Management, and our PI wants to implement Galaxy for all the users (about 10) on the cluster and manage all job submissions through a job scheduler. So, to answer your question, we are not really using any scheduler at this point, but only a stand alone server with a local installation of Galaxy. Our Cluster should be assembled and installed by the end of May, so I¹m trying to gather as much information as possible in preparation for the deployment. Based on your experience, what do you think I should focus on to ensure we maximize outcome and reduce the possibility of mistakes? In other words, any lessons learned that you would like to share will be greatly appreciated. Thanks again, Carlos Lijeron.
