E4S 23.05 - Perlmutter¶
The e4s-23.05
stack is built using the Spack branch e4s-23.05 on Perlmutter using the gcc, nvhpc, and cce compilers. This stack can be loaded by running:
module load e4s/23.05
You can also load the same software stack via module load spack/e4s-23.05
Here is a breakdown of the installed specs by environments:
Spack Environments | Compiler | Root Specs | Implicit Specs | Total Specs |
---|---|---|---|---|
gcc | gcc@11.2.0 | 90 | 253 | 343 |
cuda | gcc@11.2.0 | 42 | 91 | 133 |
data | gcc@11.2.0 | 11 | 35 | 46 |
math-libs | gcc@11.2.0 | 20 | 42 | 62 |
tools | gcc@11.2.0 | 9 | 34 | 43 |
nvhpc | nvhpc@22.7 | 6 | 19 | 25 |
cce | cce@15.0.0 | 9 | 19 | 28 |
Spack Configuration¶
When you load the e4s/23.05
module you will see several environments with their own isolated software stacks. You can list the environments by running the following:
elvis@perlmutter> spack env list
==> 7 environments
cce cuda data gcc math-libs nvhpc tools
To activate an environment, run the following:
elvis@perlmutter> spack env activate gcc
Overview¶
You can see a list of all available packages via spack find
. For example, to see the packages within the gcc
environment:
spack env activate gcc
spack find
Using the -e
flag, you can list packages without activating an environment.
spack -e gcc find
To format the output of spack find
, use the --format
flag. Shown below is a command to see a list of packages:
spack -e gcc find -x --format "{name}@{version}%{compiler} {variants} /{hash:7}
A few useful spack find
commands for querying packages:
# list all hdf5 packages with full hashes, 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
