AWS ParallelCluster + AWS Batch

Today I'm going to demonstrate running High Performance Conjucate Grandients (HPCG) in a containerized workload. This takes advantage of AWS ParallelCluster, AWS Batch, and OpenMPI.

First install aws-parallelcluster:

$ pip install aws-parallelcluster

Applicability

The instructions below apply to older versions of Homebrew which still provide switch capability.

For current Homebrew, you'll likely need to keep Versions around, and build locally. Here's my versions repository https://github.com/rdump/homebrew-versions

MacPorts is now keeping versioned installations available as well, by default.

Nginx Double A

A primitive Double A (AAA-minus-Accounting) RBAC system implemented in declarative Nginx config.

Background

So I noticed https://github.com/alexaandru/elastic_guardian, a simple AAA reverse-proxy to sit in front of Elasticsearch. Reading the source and comments tickled my "why is this in code not config?" funnybone.

I asked @alexaandru (https://twitter.com/jpluscplusm/status/438339557906735104) who told me it was mostly the resulting complexity of the nginx config he tried that prompted him to write it.
