2.1. Adding the Roll

The APBS Roll is available for two different architectures: i386 and x86_64. Make sure you choose the correct iso image with the right APBS Roll for your specific hardware.

First please make sure you downloaded the iso images correctly (see MD5 checksums below) and then burn the iso image to a CD.

The APBS Roll can be installed during the Frontend installation step of your cluster (refer to section 1.2 of the Rocks users guide) but it can also be installed directly onto a running system.

The APBS Roll is added to a Frontend installation in exactly the same manner as other Rocks rolls. Specifically, after the base Roll is added the installer will once again ask if you have another Roll (see below). Select 'Yes' and insert a CD with the APBS Roll.

When you install the APBS Roll this way it will automatically be incorporated into the distribution for compute nodes in your cluster. This method the easiest and most natural way to install rolls in a Rocks cluster.
