That depends on whether your runner uses that option. Note that it's used directly by the local runner to define the size of a worker pool which will be used to start local job processes. I don't know how your runner is written so I don't know what, if anything, it would do in that context. > This instance of Galaxy will be accessed by some 50 users. So can > threadpool_workers be set to 50?? It can probably be significantly less than that, since the likelihood of all 50 users making concurrent requests is low. Threads incur some overhead, so I'd start with a lower value and increase it if you find that the server is not handling all of the requests. Also, because of limitations in the way threading ing the Python interpreter is written, you may want to run multiple server processes rather than increasing threads. Details on how to set this up are in the documentation at usegalaxy.org/production > Also, When a job is completed it shows the output file into the history > window where there is option to save output file.

The easiest way for users to set and send in the full error report is to set the 'smtp_server' and 'error_email_to' options in universe_wsgi.ini. This will enable the "bug report" icon you see on our public server. --nate > > Thanks and Regards > Hari > > On Thu, Feb 24, 2011 at 6:43 PM, Nate Coraor <n...@bx.psu.edu> wrote: > > > hari krishna wrote: > > > Hi, > > > > > > What is the difference between threadpool_workers and > > > local_job_queue_workers*.* > > > > Hi, > > > > threadpool_workers is the number of threads which will be available to > > serve web requests.
