SDSC "cilk" roll

Overview

This roll bundles the cilk parallel programming system.

For more information about the various packages included in the cilk roll please visit their official web pages:

• MIT CILK is a linguistic and runtime technology for algorithmic multithreaded programming.

Requirements

To build/install this roll you must have root access to a Rocks development machine (e.g., a frontend or development appliance).

If your Rocks development machine does not have Internet access you must download the appropriate R source file(s) using a machine that does have Internet access and copy them into the src/<packages> directories on your Rocks development machine.

Dependencies

The sdsc-roll must be installed on the build machine, since the build process depends on make include files provided by that roll.

The roll sources assume that modulefiles provided by SDSC compiler rolls are available, but it will build without them as long as the environment variables they provide are otherwise defined.

Building

To build the cilk-roll, execute this on a rocks development machine (e.g., a frontend or development appliance):

% make 2>&1 | tee build.log

A successful build will create the file cilk-*.disk1.iso. If you built the roll on a Rocks frontend, proceed to the installation step. If you built the roll on a Rocks development appliance, you need to copy the roll to your Rocks frontend before continuing with installation.

Installation

To install, execute these instructions on a Rocks frontend:

% rocks add roll *.iso
% rocks enable roll cilk
% cd /export/rocks/install
% rocks create distro

Subsequent installs of compute and login nodes will then include the contents of the cilk-roll. To avoid cluttering the cluster frontend with unused software, the cilk-roll is configured to install only on compute and login nodes. To force installation on your frontend, run this command after adding the cilk-roll to your distro

% rocks run roll cilk host=NAME | bash

where NAME is the DNS name of a compute or login node in your cluster.

In addition to the software itself, the roll installs cilk environment module files in:

/opt/modulefiles/applications/cilk

Testing

The cilk-roll includes a test script which can be run to verify proper installation of the roll documentation, binaries and module files. To run the test scripts execute the following command(s):

% /root/rolltests/cilk.t
