MCS HPC
by Craig Stacey 10 Aug '09

10 Aug '09

Hey, gang. As most of you know, Ti officially moved into MCS Systems this month (at least, I'm pretty sure he did. We're all acting like it happened, regardless). One of the roles Ti's going to be filling with this move is allowing me to remove myself from the day to day dealings and goings on with the HPC side of the world. I've asked Ti to take on a "team lead" role for HPC in MCS and the CI. This makes me a very happy boy, since Ti's got a lot of experience in this space, has a lot of good ideas, and is great to work with. It also means I can focus on other areas of concern to me, such as the overall organization of IT in CELS, figuring out an IT roadmap that makes sense, integrating support for the new organizations we'll be dealing with, circumventing gravity, and inventing a new shade of blue. It's going to take a little time for Ti to come up to speed on the stuff we care about in HPC, and you should expect him to be scheduling a gathering of minds to do a mind meld and brainstorming session on paths forward. I'll be pulling him into a number of projects as well. This feels pretty good to me. Let me know if you have any feedback or questions. == Craig Stacey, IT Manager stace(a)mcs.anl.gov

7/31 is a Friday. It's the last day for many of our students. And it's SysAdmin Day. Let's do something cool after work. I'm happy to host something at my place, but we can do whatever. == Craig _______________________________________________ This is the CELS Sysadmins mailing list.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Aidan is having a pretty bad reaction to the amoxicillin for his ear infection and so I'm going to take him to the Dr. first thing in the morning. After that I'm heading downtown to the Prudential Center. Please mark me down for a half day vacation. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) iEYEARECAAYFAkpw+5EACgkQ4RgdOxQVi0ARyACfS2K3lGqpijcCPnPG7JQkZx3z EzsAnRz9494Xxtt9W2l4Apk5+aADUvDi =yYC4 -----END PGP SIGNATURE-----

Interesting read on meetings and scheduling and how we work.
by Craig Stacey 29 Jul '09

29 Jul '09

http://www.paulgraham.com/makersschedule.html I'd be interested in your thoughts on this -- do you consider yourself on a "makers" schedule? Would it be more productive if we tried to work in this context and set aside a day (or portion of a day) that's reserved for meetings? Would "office hours" help? == Craig

[CELS Sysadmins] RT outage tomorrow @ 11am

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, In my ongoing effort to retire aha.mcs.anl.gov, I will be moving the RT database to our new systems only MySQL server, coredb.mcs.anl.gov. There will be a 15-20 minute outage, at which time the RT web interface will be unavailable. I will also disable mail to the server, in order to have it queue up while the database moves. Please let me know if there are any issues/concerns.

Re: [HPC-Admins] [CELS Sysadmins] [systems] userbase db

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 So the database has been moved and I've successfully tested the MCS accounts pages. The python scripts on the command-line are failing, however. I'm going to try to get them fixed asap, but for now the data is moved and live on userbase.mcs.anl.gov. I'm on MUD or Jabber if you have any questions.
