<title>Tuning Cores and Jobs</title>
|
||||
|
||||
<para>Nix has two relevant settings with regards to how your CPU cores
|
||||
will be utilized: <xref linkend="conf-cores" /> and
|
||||
<xref linkend="conf-max-jobs" />. This chapter will talk about what
|
||||
they are, how they interact, and their configuration trade-offs.</para>

|

builds. Nix will still substitute from binary caches, and build

remotely if remote builders are configured.

<para>The <xref linkend="conf-cores" /> setting determines the value of
|

<envar>NIX_BUILD_CORES</envar>. <envar>NIX_BUILD_CORES</envar> is equal
|

to <xref linkend="conf-cores" />, unless <xref linkend="conf-cores" />
|

equals <literal>0</literal>, in which case <envar>NIX_BUILD_CORES</envar>
|

will be the total number of cores in the system.</para>
|

|

<para>The total number of consumed cores is a simple multiplication,
|
||||
<xref linkend="conf-cores" /> * <envar>NIX_BUILD_CORES</envar>.</para>
|

|

<para>The balance on how to set these two independent variables depends
|

upon each builder's workload and hardware. Here are a few example

scenarios on a machine with 24 cores:</para>

<title>Implementation Caveats</title>

<para>Here we use the post-build hook to upload to a binary cache.

This is a simple and working example, but it is not suitable for all

use cases.</para>
|

|

<para>The post build hook program runs after each executed build,
|
||||
and blocks the build loop. The build loop exits if the hook program
|

fails.</para>
|
||||
|
||||
<para>Concretely, this implementation will make Nix slow or unusable
|
||||
when the internet is slow or unreliable.</para>
|
||||
|

<para>A more advanced implementation might pass the store paths to a

user-supplied daemon or queue for processing the store paths outside

of the build loop.</para>

that the <literal>root</literal> user's default AWS profile can

create our public and private signing keys. We will sign paths

<note>
|

<title>Should <literal>$OUT_PATHS</literal> be quoted?</title>
|

<para>
|

The <literal>$OUT_PATHS</literal> variable is a space-separated
|
||||
list of Nix store paths. In this case, we expect and want the
|
||||
shell to perform word splitting to make each output path its
|
||||
own argument to <command>nix sign-paths</command>. Nix guarantees
|
||||
the paths will not contain any spaces, however a store path
|
||||
might contain glob characters. The <command>set -f</command>
|
||||
disables globbing in the shell.
