Andreas, Yes this is possible. You can also have a look at the ncbi blast+ tools written by Peter. The same is true. Usually the tool wrappers (xml) have an option preconfigured how many threads can be used... You can adjust these directly in the xml OR as we did we added the option to be adjustable by a parameter directly in galaxy. Default low number of cores, but advanced users (login email bound) can select higher thread numbers. No experience on cluster/grid tools. Hope this helps, Alex -----Oorspronkelijk bericht----- Van: galaxy-dev-bounces@lists.bx.psu.edu [mailto:galaxy-dev-bounces@lists.bx.psu.edu] Namens Andreas Kuntzagk Verzonden: maandag 26 november 2012 9:58 Aan: galaxy-dev@lists.bx.psu.edu Onderwerp: [galaxy-dev] multithreaded tools Hi, I'm wandering how galaxy supports tools that are multithreaded or multi-process. When working with lastz I noticed that it starts 4 parallel processes. Is that always so? Can this be adjusted? What other tools also are multi-process? regards, Andreas -- Andreas Kuntzagk SystemAdministrator Berlin Institute for Medical Systems Biology at the Max-Delbrueck-Center for Molecular Medicine Robert-Roessle-Str. 10, 13125 Berlin, Germany http://www.mdc-berlin.de/en/bimsb/BIMSB_groups/Dieterich ___________________________________________________________ Please keep all replies on the list by using "reply all" in your mail client.
