<para>When run, ninja normally runs a maximum number of processes
|
|
in parallel. By default this is the number of cores on the system
|
|
plus two. In some cases this can overheat a CPU or run a system out
|
|
of memory. If run from the command line, passing a -jN parameter
|
|
will limit the number of parallel processes, but some packages
|
|
embed the execution of ninja and do not pass a -j parameter.</para>
|
|
|
|
<para>Using the <emphasis>optional</emphasis> patch below allows a user to
|
|
limit the number of parallel processes via an environment variable,
|
|
NINJAJOBS. <command>For example</command> setting:
|
|
|
|
<!-- Using <command> here to make the output bold. We really don't want
|
|
users setting this now and experience shows that many users blindly
|
|
copy/paste anything in a box. -->
|
|
|
|
<screen>export NINJAJOBS=4</screen>

will limit ninja to four parallel processes.</para>
