Passing `-l$NIX_BUILD_CORES` improperly limits the overall system load. For a build machine which is configured to run `$B` builds where each build gets `total cores / B` cores (`$C`), passing `-l $C` to make will improperly limit the load to `$C` instead of `$B * $C`. This effect becomes quite pronounced on machines with 80 cores, with 40 simultaneous builds and a cores limit of 2. On a machine with this configuration, Nix will run 40 builds and make will limit the overall system load to approximately 2. A build machine with this many cores can happily run with a load approaching 80. A non-solution is to oversubscribe the machine, by picking a larger `$C`. However, there is no way to divide the number of cores in a way which fairly subdivides the available cores when `$B` is greater than 1. There has been exploration of passing a jobserver in to the sandbox, or sharing a jobserver between all the builds. This is one option, but relatively complicated and only supports make. Lots of other software uses its own implementation of `-j` and doesn't support either `-l` or the Make jobserver. For the case of an interactive user machine, the user should limit overall system load using `$B`, `$C`, and optionally systemd's cpu/network/io limiting features. Making this change should significantly improve the utilization of our build farm, and improve the throughput of Hydra.

Hammer of Thyrion (uHexen2) is a cross-platform port of Raven Software's Hexen II source.
|
|
It is based on an older linux port, Anvil of Thyrion.
|
|
HoT includes countless bug fixes, improved music, sound and video modes, opengl improvements,
|
|
support for many operating systems and architectures, and documentation among many others.
