Cray Chapel Mesos scheduler

Mesos framework scheduler for running The Chapel Parallel Programming Language (http://chapel.cray.com). Usage:

$ ./bin/chapel -locales <number of locales i.e. nodes> -master <leading-master> <chapel program (without -nl)>

This is still an experimental framework and any participation and feedback is appreciated.

Installation on an Elastic Mesos Cluster

First off, go ahead and launch a cluster at http://elastic.mesosphere.io. Then log into one of the master nodes.

$ sudo aptitude install make g++ libprotobuf-dev mercurial golang mpich2

$ wget https://github.com/nqn/mesos-chapel/archive/master.zip
$ unzip master
$ cd mesos-chapel-master
$ export GOPATH=`pwd`
$ make

Install Cray Chapel
