Updating Software On Your Cluster¶
From time to time, Scyld may release updates and add-ons to Scyld ClusterWare. Customers on active support plans for Scyld software products can access these updates on the Penguin Computing website. Visit http://www.penguincomputing.com/support for details. This site offers answers to common technical questions and provides access to application notes, software updates, product documentation, and Release Notes.
The Release Notes for each software update will include instructions for installation, along with information on why the update was released and what bug(s) it fixes. Be sure to thoroughly read the Release Notes, as they may discuss specific requirements and potential conflicts with other software.
What Can't Be Updated¶
Some packages provided with Scyld ClusterWare, such as Ganglia, are specifically
optimized to take advantage of the
BProc unified process space, which is
added to the standard Linux distributions that Scyld supports. Other
packages, such as MPICH2, MVAPICH2, MPICH3, and OpenMPI, take advantage
of features of the Scyld ClusterWare TORQUE distribution. Although there are generally
available versions of these packages that you can download from other
sources, you should use the versions provided by Scyld for best
performance with BProc and ClusterWare. Contact Scyld Customer Support
if you have questions about specific packages that you would like to use
with Scyld ClusterWare.
Users may also choose to use commercially available MPIs, such as Intel, HP, Scali, or Verari. These require specific configuration on Scyld ClusterWare. See the Penguin Computing Support Portal at http://www.penguincomputing.com/support, or contact Scyld Customer Support.
