This works on a single node + (where you've called `spack` several times) or across multiple nodes + with a shared filesystem. For example, with SLURM, you could build + `trilinos` and its dependencies on 2 24-core nodes, with 3 Spack + instances per node and 8 build jobs per instance, with `srun -N 2 -n 6 + spack install -j 8 trilinos`. This requires a filesystem with locking + enabled, but not MPI or any other library for parallelism. + +2. **Build pipelines.** You can also build in parallel through Gitlab + CI. Simply create a Spack environment and push it to Gitlab to build + on Gitlab runners. Pipeline support is now integreated into a single + `spack ci` command, so setting it up is easier than ever. See the + [Pipelines section](https://spack.readthedocs.io/en/v0.14.0/pipelines.html) + in the docs. + +3. **Container builds.** The new `spack containerize` command allows you + to create a Docker or Singularity recipe from any Spack environment. + There are options to customize the build if you need them. See the + [Container Images section](https://spack.readthedocs.io/en/latest/containers.html) + in the docs. + +In addition, there are several other new commands, many bugfixes and +improvements, and `spack load` no longer requires modules, so you can use +it the same way on your laptop or on your supercomputer. + +Spack grew by over 300 packages since our last release in November 2019, +and the project grew to over 500 contributors. Thanks to all of you for +making yet another great release possible.
