Need an one or more environments that work for all lessons:

  • multithreading w/ MKL and pyfftw
  • multiprocessing
  • pympi
  • pycuda
  • cython/numba

Pros of just 1 env:

  • simplicity
    Cons of 1 env:
  • less practise in instantiating and switching between envs - but is that a learning outcome here?

NB may need instructions on how to use something other than /home/$USER/.conda for package cache and environments:

  • package cache can grow v. large
  • only got 10GB quota on /home/$USER/.conda on ShARC
  • /data/$USER has 100GB - better suited

For the first workshop (git tag: 2018-04-12-mt-mp) I created conda environment definition files for each of the two lessons. Users spent several minutes at the start of the workshop blindly typing in commands to instantiate these environments then several more minutes waiting for conda to install the requested packages.

In future it would be much simpler to provide an activatable, pre-generated conda env containing the packages required by all lessons.
