== Other considerations ==
=== Specifying a CPU architecture ===
Cedar has two distinct CPU architectures available: [https://en.wikipedia.org/wiki/Broadwell_(microarchitecture) Broadwell] and [https://en.wikipedia.org/wiki/Skylake_(microarchitecture) Skylake]. Users requiring a specific architecture can request it when submitting a job using the <code>--constraint</code> flag. Note that the names should be written all in lower-case, <code>skylake</code> or <code>broadwell</code>.
An example job requesting the <code>skylake</code> feature on Cedar:
<pre>
#!/bin/bash
#SBATCH --account=def-someuser
#SBATCH --constraint=skylake
#SBATCH --time=0:5:0
# Display CPU-specific information with 'lscpu'.
# Skylake CPUs will have 'avx512f' in the 'Flags' section of the output.
lscpu
</pre>
''If you are unsure if your job requires a specific architecture, do not use this option.'' Jobs that do not specify a CPU architecture can be scheduled on either Broadwell or Skylake nodes, and will therefore generally start earlier.
