Primary LanguageMakefile

SDSC "upc" roll

Overview

This roll bundles the Unified Parallel C compiler. For more information about UPC please visit the official web page

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 fftw source file(s) using a machine that does have Internet access and copy them into the src/<package> 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 and mpi rolls are available, but it will build without them as long as the environment variables they provide are otherwise defined.

Building

To build the upc-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 upc-*.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.

This roll source supports building with different compilers and for different MPI flavors. The ROLLCOMPILER and ROLLMPI make variables can be used to specify the names of compiler and MPI modulefiles to use for building the software, e.g.,

make ROLLCOMPILER=intel ROLLMPI=mvapich2_ib 2>&1 | tee build.log

The build process recognizes "gnu", "intel" or "pgi" as the value for the ROLLCOMPILER variable; any MPI modulefile name may be used as the value of the ROLLMPI variable. The default values are "gnu" and "rocks-openmpi".

Installation

To install, execute these instructions on a Rocks frontend:

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

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

% rocks run roll upc 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 upc environment module files in:

/opt/modulefiles/compilers/upc

Testing

The upc-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/upc.t
