E4S 22.11 - Perlmutter¶
The e4s-22.11
stack is built using the Spack branch e4s-22.11 on Perlmutter using the gcc, nvhpc, and cce compilers. This stack can be loaded by running:
module load e4s/22.11
You can also load the same software stack via module load spack/e4s-22.11
Here is a breakdown of the installed specs by environments:
Spack Environments | Compiler | Root Specs | Implicit Specs | Total Specs |
---|---|---|---|---|
gcc | gcc@11.2.0 | 78 | 294 | 372 |
cuda | gcc@11.2.0 | 27 | 72 | 99 |
nvhpc | nvhpc@22.5 | 5 | 7 | 12 |
cce | cce@15.0.0 | 9 | 13 | 22 |
Spack Configuration¶
When you load the e4s/22.11
module you will see several environments with it's own isolated software stack. You can list the environments by running the following:
elvis@perlmutter> spack env list
==> 4 environments
cce cuda gcc nvhpc
To activate a environment you can run the following:
elvis@perlmutter> spack env activate -V gcc
Overview¶
You can see a list of all available packages via spack find
. If you want to see packages in a particular environment, you must activate the environment first. For example, to see packages in gcc
environment you can run
spack env activate -V gcc
spack find
Alternatively you can list packages without activating an environment by using the -e
flag with name of environment.
spack -e gcc find
If you want to format the output of spack find
you can use the --format
flag. Shown below is a useful command one can run to see list of packages
spack -e gcc find -x --format "{name}@{version}%{compiler} {variants} /{hash:7}
A few useful spack find
commands you can use when querying packages
# list all hdf5 package with full hash, variants, prefix, and dependencies
spack -e gcc find -Lvpd hdf5
# list all root (explicit) specs
spack -e gcc find -x
# list all implicit (dependencies) specs
spack -e gcc find -X
# list all root specs dependent on mpi
spack -e gcc find -x ^mpi
