NERSC provides High Performance Computing system to support research in the Office of Science program offices. NERSC has one production HPC systems Perlmutter and muller which is Test system for Perlmutter.
Shown below is the buildtest configuration at NERSC. We have defined multiple slurm executors, along with settings for configuring compilers that is available on Perlmutter.

Summit is a IBM based system hosted at Oak Ridge Leadership Computing Facility (OLCF). The system uses IBM Load Sharing Facility (LSF) as their batch scheduler.
The system keyword is used to define the name of system which in this example is named summit. The
hostnames is used to specify a list of hostnames where buildtest can run in order to use this system configuration.
The system comes with several queues, for the purposes of this example we define 3 executors
that map to queues batch , test and storage. To declare LSF executors we define them under lsf
section within the executors section.
The default batch configuration is defined in defaults, for instance we set the fields pollinterval, maxpendtime
and to 30s and 300s each. The field account is used to specify project account where all jobs will be charged. This can be
customized to each site but and can be changed in the configuration file or overridden via command line buildtest build --account <ACCOUNT>.

Joint Laboratory for System Evaluation (JLSE) provides
a testbed of emerging HPC systems, the default scheduler is Cobalt, this is
defined in the cobalt section defined in the executor field.
We set default launcher to qsub defined with launcher: qsub. This is inherited
for all batch executors. In each cobalt executor the queue property will specify
the queue name to submit job, for instance the executor yarrow with queue: yarrow
will submit job using qsub -q yarrow when using this executor.
