Simulated Scan Strategies

This lesson is about...

# Are you using a special reservation for a workshop?
# If so, set it here:
nersc_reservation = None

# Load common tools for all lessons

Running on NERSC machine 'cori'
  with access to repos: mp107, desi, m1759, cosmo
Using default repo mp107

Running in Parallel

The NERSC login nodes do not support MPI, so all of the previous examples are running serially. To run in parallel, we can submit a batch job version of the above examples:
