rhel7 spack configuration and scripts
The install.sh script maintained in this repo is for documentation purposes (e.g., in case we had to reinstall the entire stack from scratch) and should not be executed as it will not use all of our existing package installs. More discussion of package installation is below.

Our spack repo is tracking the master spack branch. Spack package updates could result in additional installation of packages with little or no package source code changes. These additional installs can be avoided when installing new packages by first examining the output of the spack spec -I command. If a utility/infrastructure level package, such as cmake or mpich, is marked with a [+] symbol in the leftmost column then it means that the existing install will be used. If spack does not default to using the existing install you can append the hash of the package to the spec command.
For example, lets see what happens when we ask for a pumi install using gcc 7.3.0

Spack wants to install mpich 3.3, but we don't want to change to the new mpich version yet. So, we will get the hash of the existing mpich 3.2.1 install:
$ spack find -ldv mpich%[email protected]
==> 1 installed package
-- linux-rhel7-x86_64 / [email protected] -------------------------------
niuhmad [email protected] device=ch3 +hydra netmod=tcp +pmi+romio~verbs
then append the hash niuhmad to the spec for pumi using the ^ syntax to specify it as a dependency:
$ spack spec -I pumi@develop%[email protected] ^/niuhmad
Input spec
--------------------------------
- pumi@develop%[email protected]

And see that in the Concretized spec it is now using the existing mpich 3.2.1 install.
