Greetings, We are trying to enable job-splitting and merging on our Galaxy blast tools. We set the following parameters in the universe_wsgi.ini: use_tasked_jobs = True local_task_queue_workers = 2 Then we executed the tool "NCBI BLAST+ blastn" (from devteam's NCBI BLAST+) on a query set of 10,000 sequences. The tool's xml has the following parallelism tag: And as expected, the job was split into 10 tasks (IDs 0-9), each one with 1000 sequences. Four tasks started running simultaneously. Those four tasks have completed, but now there is no indication that the other 6 tasks have begun running, and the job on the GUI is still in the yellow-state in History. It has been nearly an hour, and still no sign of those tasks or any job running. What could be the cause of this? ---------------------------------------------- Ravi Sanka ICS – Sr. Bioinformatics Engineer J.
