Critical File Server Upgrade, Wed, March 16, 9:30pm-12:00

As many of you have doubtless noticed, the file server holding your home directories has been misbehaving in recent weeks. To address that, we'd like to take down the file server for hardware maintenance the evening of Wednesday, March 16th, from 9:30pm until midnight.

During the outage your home directory will be unavailable and you'll not be able to log in. Your email, as a DoIT service, will be unaffected by the outage.

We also recommend you not have any CONDOR jobs scheduled during that time.

Jan 15 2016: Python library updates and Git

The Python deep learning support library Theano has been added to Python 2 and 3.

Since the last time we checked, several additional scientific packages have been ported to Python 3 (matplotlib, in particular). So, for the moment, Python 2 and 3 have parallel scientific libraries. Details.

We have recently installed an authenticated, web-managed Git repository tool, available to all Biostat users. Details.

Jan 11 2016 : Project and Compute file server down [Updated 6:44pm]

Status: (6:44pm) the compute file server is back up.

Due to a lengthy power outage in one of our server rooms, a large number of compute machines, and one main file server, were offline since Sunday.

The compute machines are mostly back now.

It seems there was a power surge when the power came back on, which has caused problems for the project/compute file server. We're currently working (9:30am) to move the drives to a different chassis and bring that service back online. I'll update this page when that service is back.

Dec 21 2015 - "Identity Finder" software required by CIO

The Office of the CIO for the UW has mandated that we must scan all UW-owned computers in the department for restricted data — in this case, Social Security Numbers.

For this, the CIO's office has gotten a campus license for software called "Identity Finder" which we (meaning BCG) must install, run, and report the results of to them. We are using our update manager, called Tivoli Endpoint Manager, to remotely deplay the Identity Finder client software.

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.
