Overview

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 skeleton 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. The build process requires the XYZ libraries and assumes that the xyz modulefile provided by the SDSC xyz-roll is available. It will build without the modulefile as long as the environment variables it provides are otherwise defined.

Building

To build the skeleton-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 skeleton-*.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".

The roll supports specifying building with/for python versions other than the one included with the o/s. To use this feature, specify a `ROLLPY` make variable that includes a space-delimited list of python modulefiles, e.g.,

% make ROLLPY=opt-python 2>&1 | tee build.log

For gnu compilers, the roll supports a `ROLLOPTS` make variable value of 'avx' or 'avx2', indicating that the target architecture supports AVX/AVX2 instructions.

Installation

To install, execute these instructions on a Rocks frontend:

% rocks add roll *.iso
% rocks enable roll skeleton
% cd /export/rocks/install
% rocks create distro
% rocks run roll skeleton | bash

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

/opt/modulefiles/applications/skeleton

Testing

The skeleton-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/skeleton.t
