Installation of SuSE Packages

Date Opened: Feb 14, 2012
Impact: 2 = inconvenience
Contact Person: Robert, Brad
Issue: If a user would like to install a package that is on the list of SuSE supported packages but not included in the default install, could the user send an email to help desk to get the package installed?
Updates:
  • Feb 14: Tech staff may have declined installation of some SuSE packages to make it easier to track what is installed on each machine. But, if the user can request their desired packages after each re-install, then we don't need to worry about tracking what's on each machine.

Linux 12.1 Upgrade

Date Opened: Jan 31, 2012
Impact: 3 = research affected
Contact Person: Imager Tech
Issue: When will the imager upgrade to 12.1 happen? Support ends in Sept.
Updates:
  • Feb 21: Brad will request dropbox for 12.1 installation.
  • Feb 14: Brad volunteered his machine for early adoption of 12.1. Brad is in contact with Hazita regarding problems with 12.1.
  • Feb 14: SuSE 12.1 includes "ownCloud", but it is not a soln to the "sharing large files" issue.
  • Feb 07: Tech staff is looking into the possibility of using dropbox. Glen will get an update.
  • Jan 31: When will the cluster be moved to 12.1? Cluster (currently 11.4) can support 12.1. Dave is contacting other users.
  • Jan 31: When will the upgrade happen for imager? It should be in June or early July but no later to allow for Siggraph prep.

Sharing Large Files

Date Opened: Jan 31, 2012
Impact: 2 = inconvenience
Contact Person: Anika, Wolfgang
Issue: What is the best way to share large files with other universities?
Updates:
  • Feb 21: Can Imager buy raid space (min 2TB) dedicated for file transfer? Glen will ask Mike if we can add to existing raid space or buy new raid space. Glen will get price quote. Files in space should auto-delete in x weeks.
  • Feb 21: Mike does not want to use FTP server.
  • Feb 14: What if the dept got a 3TB FTP server? Files would be automatically deleted in 3 days. Anyone can access files. Files can be encrypted.
  • Feb 14: It is not possible to symlink to machine dependent space like /var/tmp and /scratch. We can access this space through scp, but then the user needs a login.
  • Feb 07: It is possible to create a symlink in your webpage space to files on NetApps space (imager) or raid space.
  • Feb 07: There is 230MB on FTP server (47MB free today, (help desk uses it for SuSE installs)). Too small to use for transferring files.

ICICS Cluster Performance

Date Opened: Jan 31, 2012
Impact: 3 = research affected
Contact Person: Hagit, Anika
Issue: If you have processes that read/write a lot that you want to run on the cluster, what's the best way to run these processes?
Updates:
  • Feb 21: Glen will contact Hagit about using new space that's better for I/O ops (Sun Storage 7310).
  • Feb 21: Cluster moved to isolated LAN. Need to ssh into remote.cs. Looks like cluster will not be upgraded to 12.1 with rest of machines.
  • Feb 14: PiCloud too expensive.
  • Feb 07: Brad has requested quotes for PiCloud and Matlab Distributed Computing Server (which uses Torque scheduler).
  • Feb 07: Glen will ask if help desk will allow use of PiCloud to create cluster with PSM's machines. How will updates and patches work?
  • Feb 07: What is the future of the cluster? What OS is it using? Can it support 12.1? Glen will ask Sean or Mike.
