It's definitely an experimental feature at this point, and there's no wiki, but basic support for breaking jobs into tasks does exist. It needs a lot more work and can go in a few different directions to make it better, but check out the wrappers with <parallelism> defined, and enable use_tasked_jobs in your universe_wsgi.ini and restart. That's all it should take from a fresh galaxy install to get, iirc, at least BWA and a few other tools working. If you want a super trivial example to play with, change the tool .xml for text tool like "change case" to have <parallelism method="basic"></parallelism> and give that a shot.
If you decide to try this out, do keep in mind that this feature is not at all complete and while there's a long list of things we still want to experiment with along these lines suggestions (and especially contributions) are absolutely welcome. -Dannon On Feb 15, 2012, at 11:36 AM, Peter Cock wrote: > Hi all, > > The comments on this issue suggest that the Galaxy team is/were > working on splitting large jobs over multiple nodes/CPUs: > > https://bitbucket.org/galaxy/galaxy-central/issue/79/split-large-jobs > > Is there any relevant page on the wiki I should be aware of? > > Specifically I am hoping for a general framework where one of the tool > inputs can be marked as "embarrassingly parallel" meaning it can be > subdivided easily (e.g. multiple sequences in FASTA or FASTQ format, > multiple annotations in BED format, multiple lines in tabular format) and > the outputs can all be easily combined (e.g. by concatenation in the > same order as the input was split). > > Thanks, > > Peter > ___________________________________________________________ > Please keep all replies on the list by using "reply all" > in your mail client.
