---++++ 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 28: Dropbox will not be included in 12.1 installation.  Users can install dropbox themselves.
   * Feb 14: Brad volunteered his machine for early adoption of 12.1. Brad is in contact with Hazita regarding problems with 12.1.
   * Jan 31: Cluster (currently 11.4) can support 12.1 but will unlikely be upgraded to 12.1 when imager is upgraded.
   * Jan 31: Upgrade for imager 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: 
   * Mar 27: (Glen's email) It is possible to set up a separate 2TB partition with auto-delete capabilities.
   * Mar 27: Can we have a separate partition from imager-raid and psm-raid so that we can automatically delete files within the new partition?  Will the cluster be able to access this new space?
   * Mar 27: The imager-raid and psm-raid space is on a 7310 filesystem.  The cost to increase this space by a minimum of 2TB is $1/GB (so $2000 for 2TB).
   * 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 14: !SuSE 12.1 includes "ownCloud", but it is not a soln to the "sharing large files" issue.
   * 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: 
   * Mar 27: Glen will contact Anika instead of Hagit.
   * 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?



---++++ Meeting notes
   * Check [[ConferenceFreezeDates][Conference Freeze Dates]] page monthly and notify tech staff of any new freezes.
   * Check imager disk space list monthly for users over 25GB.
   * Cheryl and Brad are leaving around June, and Robert is leaving in May.  We need replacements.
