May 15, 2015 - Office 365 Transition

In June, DoIT will start their big push to move remaining email users (mostly faculty and staff) from the old email system to Office 365.

Though we are not yet ready to move the department to Office 365, we would like to let everyone know where we are in the process and to give you some things to think about in anticipation of this change.

The goal of campus is to have everyone consolidate their various email addresses into one. Though it will still be possible to have more than one email address, at the moment consolidation is the simplest option.

April 27 2015, 3:00pm - File Server Slow-down (Resolved)

One of our file servers is exhibiting very odd network behavior, which makes some machines unable to talk to it.

Mostly this has affected /z/Comp and computational disk space. But the slow-down has caused some other services to slow down as a result, too. In particular the departmental web server may be a bit sluggish.

We have a workaround in place which may result in generally slower access to that server. We will leave that slower configuration in place until we can identify the cause of the more severe networking problem.

Nov 6 2014 - Python 2.7.6 Library Update: iPython Notebook, OpenFST

The /s/bin/python version 2.7.6 has recently been upgraded with some libraries:

  • SymPy
  • iPython - an interactive notebook interface to Python; using ipython notebook will open a browser window, giving enhanced graphical capabilities. The most important note: use SHIFT-RETURN to send a python command to the interpreter.
  • PyFST, an interface to the OpenFST weighted finite-state transducers library.

October 1 2014 - File Server Outage Oct 4, 9:00pm

What: All Biostat compute, file serving, and BCG condor resources
When: Sunday Oct 4, from 9pm to 10pm

Summary: The BCG requires an outage to all biostat file servers in order to apply patches to improve stability. Home directories and project/computational spaces will all be affected. The file servers for biostat will be unavailable Sunday Oct 4th starting at 9pm for a period of one hour.

If critical compute jobs need to be running during this outage please contact us ASAP.

September 29 2014 - MSC Power Outage (4am-7am)

From the NOC:

The Electric Shop is planning a power outage at MSC on Tuesday,
September 30, between 4:00 a.m and 7:00 a.m. This outage has the
potential to affect any of the network switches at MSC during the
outage window.

Long-running batch jobs on local MSC machines, as well as condor jobs submitted from local MSC machines, should probably be suspended until later in the morning of September 30th.

September 17 2014 - Linux /s/bin/python at 2.7.6

The default version of Python for Linux, found in /s/bin/python, is now at 2.7.6. It includes these additional modules:

  • scipy
  • numpy
  • matplotlib
  • xlsxwriter

Python 3.4 is available with the command python3. It has the same additional modules as 2.7.6 except matplotlib. It will likely be 2-3 years before a 3 series of Python is the local default.
