Hi Roberto, It looks like you are probably still using the default sqlite database. You’ll want to update to using e.g. postgres when exploring these more database intensive functions. See e.g.: https://wiki.galaxyproject.org/Admin/Config/Performance/ProductionServer#Swi... Thanks for using Galaxy, Dan On Feb 5, 2015, at 8:24 AM, Roberto Alonso <roalva1@gmail.com> wrote:
Hello,
I am trying to use parallelism in Galaxy. I added this entry to the tool xml config:
<tool id="fa_gc_content_1" name="Compute GC content"> <description>for each sequence in a file</description> <parallelism method="basic" split_size="8" split_mode="number_of_parts"></parallelism>
But when I run the job, the log shows the next:

So when one task tries to run it fails, it seems that the database is locked by other task. When I run with 4 splits it never happen, but with 5 it begins to happen. Indeed with 5 splits sometimes it doesn't happen, but since 6 it always occurs.
Could you please help me?
