Hi Nate, Thanks for ur reply. I have made a job runner which will submit job to job meta-scheduler, which can handle 200 jobs concurrently. So is it safe to set local_job_queue_workers = 200 ??
This instance of Galaxy will be accessed by some 50 users. So can threadpool_workers be set to 50??
Also, When a job is completed it shows the output file into the history window where there is option to save output file. But when job is not successful instead of generating output file, it generates a job error file. How can i place this error file in the place of output file in the history window.
Thanks and Regards Hari

Hi,
threadpool_workers is the number of threads which will be available to serve web requests. This means the number of possible concurrent browser connections, but this value can remain fairly low since most web transactions are < 1 second.
local_job_queue_workers is the number of tool processes that Galaxy will start and allow to run at the same time. For example, if you set this value to 2 and then submit 3 jobs, the third one will wait for one of the first two to finish before it will execute.
what is the maximum size that i can set local_job_queue_workers value?
There's not really a maximum, but it doesn't make sense to set this much higher than the number of CPU cores in your server. I would suggest setting it to (cores - 1) to ensure the Galaxy process itself always has a core to run on.
