Hi, I'm working on the project for Google Summer of Code: https://www.nescent.org/wg_phyloinformatics/Phyloinformatics_Summer_of_Code_... Demo instance can be found here: http://137.110.191.252:8080/ (under the "Phylogenetics" section) As you can see, detailed results of the SLAC analysis are generated on demand. In this version computation is done when the request is handled (in datamonkey controller). It bypasses the job queue and I guess it might not be considered as the best approach. I was thinking about creating jobs for those on-demand computations. What do you think about this solution? I understand that to accomplish this, I have to create another tool and put my code there. Is it the only way to use the job queue? Is it possible to add a job which isn't displayed in the history box? best regards, Filip Balejko
