Accomplishments past period:
ONGOING: Testing and bug fixing of current Athena release.
Last Month's goals:
PROGRESS: Create new Linux installer based on a more current RHEL 4
Kernel
that includes necessary drivers for Dell Optiplex 745.
PROGRESS: Develop plans for full release targeted for next summer.
Community Milestones Met:
Patch release containing JDK 1.5 update, proprietary video driver
support for Linux, Firefox update and security patches for Solaris.
Other Accomplishments:
* Follow-up patch release adding ksh to Linux because a class needed it.
* Several customer site visits that resulted in pro-actively adding AHCI
support to the Athena installer.
Next month's goals:
ONGOING: Testing and bug fixing of current Athena release.
OLD: Create new Linux installer based on a more current RHEL 4 Kernel
that includes necessary drivers for Dell Optiplex 745.
OLD: Develop plans for full release targeted for next summer.
NEW: Obtain Optiplex 755 (745's replacement) and begin hardware
qualification on that.
Next Community Milestone(s):
Patch release containing Kerberos 5 support for Discuss, JDK 1.5 update,
proprietary video driver support for Linux, Firefox update and security
patches for Solaris.
Issues:
Kerberos 4 mail clients like mh, xmh, and exmh are going to die when
Kerberos 4 is shut down. Our plan is to investigate amending inc to
support Kerberos 5 as soon as the mail servers get Kerberos 5 support.
JDK 1.6 appears to interact poorly with AFS home directories under
Solaris, taking several minutes to start.
Sidney-Pacific (the graduate dorm) bought four Dimension 9200s to
upgrade their Athena cluster and found that they were unable to
install them. They are waiting on us for a new rev of the installer.
Key learnings:
Additional comments:
Athena Monthly machine counts:
Method: On install, machines get a unique ID. Each day every system
reports its existence to a central syslog. This method over-counts
systems installed multiple times. Systems running Athena than 9.0 or
earlier are not counted.
Summary: Here we see the effect of cluster renewal beginning to
replace Suns with Linux systems.
SYSTYPE 03/07 04/07 05/07 06/07 07/07 08/07 Delta
LINUX 810 798 774 792 779 815 +36 (Renewal)
SUN 320 315 308 314 303 299 -4
Count of systems registered for RHN (Non Athena update):

Monthly Athena Login counts:
Method: By reviewing of the logs of the service that makes
personalized notifications to users at login time, we are able to count
the number of unique Athena logins. Here we display the total number of
logins over a four week period, the number of logins by unique user ID
and the median number of logins per unique user ID.
Date: 03/07 04/07 05/07 06/07 07/07 08/07
Total: 225843 250846 217514 143980 153036 147026
Unique: 9838 9867 9730 7907 7212 9286
Median: 9 10 8 4 5 4
Breakdown for current month:
(Total of unique logins will be less than the sum of the sources,
since each source login only gets counted once.)
Total logins for four week period: Ending Sat, 1 Sep 2007
147026 ( other 104201 quickstation 21687 cluster 21138 )
Unique logins for four week period:
9286 ( other 5394 quickstation 5109 cluster 3807 )
Median logins for four week period:
4 ( other 3 quickstation 2 cluster 2 )
