A note on capacity
</pre>
==== A note on capacity ====
The default capacity of a host added to the host database is 2. This means that once the load average on that machine exceeds 2, kojid will not accept any additional tasks. This is separate from the maxjobs item in the configuration file. Before kojid will accept a job, it must pass both the test to ensure the load average is below capacity and that the current number of jobs it is already processing is less than maxjobs. However, in today's modern age of quad core and higher CPUs, a load average of 2 is generally insufficient to fully utilize hardware. As there is not an option to set the capacity of the host via the command line tools, it must be done manually in psql.
<pre>
koji@localhost$ psql koji
koji=# select (id, name, capacity) from host;
row
--------------------------------
(1,kojibuilder1.example.com,2)
(2,kojibuilder2.example.com,2)
(2 rows)
 
koji=# update host set capacity = 16 where id = 1;
UPDATE 1
koji=#
