Documentation and Support

• For a complete reference, the Scyld ClusterWare documentation set consists of:

  • The full Installation Guide containing broader, more detailed information for installing and configuring the cluster.

  • The Administrator’s Guide describing how to configure, maintain, and update the cluster.

  • The User’s Guide and Reference Guide describing the commands, architecture, and programming interface for the cluster, including sample programs.

  • The Release Notes containing release-specific details, including information about known issues and workarounds.

  These product guides are available in two formats, HTML and PDF.

• Visit the Penguin Computing Support Portal at https://www.penguincomputing.com/support using the username and password you received for this evaluation, and click on Application Notes for information about running specific applications.

• Note: If you ssh -X from a remote system that executes a more recent version of X11 to the master node, some graphical programs may fail with an error of the form:

  Gdk-ERROR **: BadMatch (invalid parameter attributes)
    serial 798 error_code 8 request_code 72 minor_code 0
  

  For a workaround, try setting the ssh client host X11 depth to 8:

  [root@scyld ~]# export XLIB_SKIP_ARGB_VISUALS=1
  

  on the master node before running the failing program. If that is successful, then consider adding that export to /etc/bashrc or to an individual’s ~/.bashrc.
