Galaxy job runner queue management questions
by Ry4an Brase 17 Mar '11

17 Mar '11

As use of our Galaxy installation is picking up, we're getting a lot of requests for greater fairness and transparency in the Galaxy job runner area. As I understand things the primary tool Galaxy gives us to affect processing order and wait times with our torque-based setup is the ability to map specific tools to varying queues or to keep them on a local-runner. On one end of the spectrum I could see a simple division of small/fast/light jobs on local and big/heavy/slow job on a single cluster queue. On the other extreme one could set up a queue per tool and use sophisticated queue management stuff on the torque side of things to balance capacity across tools, users, expected processing time, etc. How are other sites handling this? -- Ry4an Brase 612-626-6575 Software Developer Application Development University of Minnesota Supercomputing Institute http://www.msi.umn.edu

Dutch Galaxy Hackathon
by Freek de Bruijn 16 Mar '11

16 Mar '11

Hi everyone, Galaxy is in use for quite some time now in The Netherlands. In April, NBIC (Netherlands Bioinformatics Centre, www.nbic.nl) is organizing a Hackathon and Galaxy is one of the projects that have been selected. A group of around 8 developers will work on a number of subjects for two days. We are planning to learn more about Galaxy and improve (our use of) it. Potential subjects are: - Call another workflow within a workflow - Loop over files in a directory - Support interactive visualization - Improving NBIC Galaxy UI - Making the access to NGS/Proteomics pipelines easier - Customization of the tool panel - Improving tool installation We would really appreciate suggestions and other input from the Galaxy Team. Thanks in advance! More information is available on our Hackathon wiki: https://wiki.nbic.nl/index.php/NBIC_Galaxy_Hackathon_project.

username or email address from tool
by Glen Beane 16 Mar '11

16 Mar '11

I am implementing a new tool and I would like to reference the galaxy username and/or email address of the galaxy user running the tool (we require all of our users log in). Can this information be referenced in a tool .xml file? -- Glen L. Beane Senior Software Engineer The Jackson Laboratory (207) 288-6153

Running a workflow programatically
by Darren Brown 16 Mar '11

16 Mar '11

Hello folks, I am using a workflow that needs to be run many times on many different inputs. I have hacked around and figured out how to pull multiple inputs from a history, but I am a little baffled on how to run a galaxy workflow programatically. I have searched around fairly exhaustively and am wondering if this is something that anyone else has come across and accomplished. And links or pointers? Take care, Darren

Fwd: Galaxy process
by SHAUN WEBB 16 Mar '11

16 Mar '11

Further to my email below. I have a data library that contains many ~117Gb of NGS data, uploaded via file system path. This library was always slow to open (about 10s) but now takes several minutes or not at all. Thanks for any help on this. I am still experiencing a memory leak that I can't pinpoint and it is only dissipated by restarting the server. At the moment my debugging level is set to INFO. Is there anything I can change in the universe file to try to trace this. Thanks!

Database cleanup and user management
by Sebastian J. Schultheiss 15 Mar '11

15 Mar '11

Dear Galaxy Developers, we are experimenting with cleanup strategies for our production galaxy server that is used by the public. How are you treating the user- uploaded data on galaxy-main? We would like to see how much space is used by an individual user and evenutally be able to remove them after some time of inactivity (>180 days?), ideally preceded by 1-2 warning emails. Can the current cleanup scripts handle that? Thanks for your help! -- Sebastian

Connecting Galaxy to multiple Remote Clusters?
by Joe Cruz 15 Mar '11

15 Mar '11

Hello, I've read through past emails that connecting Galaxy to a remote cluster is possible but I wanted to ask if it was possible to setup Galaxy as a standalone webserver and have it use multiple remote clusters (multiple head nodes each with their own compute nodes) and if so what the best strategy to implement this is? Also on one of these clusters we are not able to mount an NFS directory onto the compute nodes, since we do not own/manage it. Your help is greatly appreciated. Thanks, Joe

testing updates on Galaxy CloudMan
by Isabelle Phan 13 Mar '11

13 Mar '11

I am at step 2 of Galaxy CloudMan deployment. "Now, manipulate Galaxy as desired." How do I test that my updates are working before proceeding to step 3? I assumed I could just type 'run.sh'. This starts Galaxy but: - fasta files do not display in the middle pane - png images generated by e.g. boxplot do not display in the middle pane - saving images does not work (get empty file) I need to know how people are customizing their cloud instance of galaxy. If it is NOT possible to test modifications in the usual way PLEASE would somebody simply confirm? I really would appreciate a response.

Upload files from filesystem paths - backwards checkboxes
by Peter Cock 12 Mar '11

12 Mar '11

Hi all, Via the Galaxy admin interface, I'm currently importing some BAM files into a library from the local file system. Since they are big, I don't want Galaxy to copy them. So I looked at the "Copy data into Galaxy?" option and made sure it wasn't ticked. Galaxy did copy the file :( I looked at the interface again, and see you have: > Copy data into Galaxy? > [check box] No > Normally data uploaded with this tool is copied into Galaxy's "files" > directory so any later changes to the data will not affect Galaxy. > However, this may not be desired (especially for large NGS > datasets), so use of this option will force Galaxy to always > read the data from its original path. You've got a tick box labelled "No" so it does the opposite to the question above it. That is a HORRIBLE interface. I can't be the first person to be tricked by it, can I? I would urge you to remove the work "No" and flip the meaning (and default) to match. But that could confuse existing admin users used to clicking from previous habit. How about making it a select parameter instead, with options "Copy files (default)" and "Link to files" which is very explicit? Likewise for the "Preserve directory structure?" setting, I'd remove the "No" caption and flip the setting, or just replace the backwards tick box with a select parameter offering "Preserve directory structure" and "Place in selected folder" (or something like that). Pretty please? How about if I write and test the patch? Peter
