Updates to Building Astrobear tutorial

I've made some updates to the Building Astrobear tutorial to reflect the system changes brought on by the Great Crash:

  • Bluehive and Bluegene now sport reminders to set up a VPN connection, as well as links to the University IT page that explains how to do so.
  • Grass's build instructions have been updated with the new module list, as well as how to enable modules in your bash environment.
  • A new section has been added for alfalfa build instructions. This section looks a lot like grass, except that it also has a VPN reminder.

Meeting Update for week of July 10, 2011

Alfalfa, the new grass-style machine, is now <palpatine_voice>fully operational</palpatine_voice>. It can be reached via ssh:

ssh <username>@alfalfa.pas.rochester.edu

Users still need a VPN to connect to alfalfa from off-campus, but no VPN is needed to connect from another machine in the PAS domain.

All of the modules accessible on grass and clover are accessible on alfalfa, as is ifort. AstroBEAR's Makefile.inc.grass seems to work for alfalfa as well.

It turns out we lost email notifications when the wiki was brought back online, due to changes in the department's SMTP protocol configurations. This problem has since been fixed, and users are receiving emails about tickets again. We are still working to restore notifications about repository checkins.

I've created a page about scaling in AstroBEAR; it's still pretty rudimentary, but it's at least RFC-ready at this point. This is part of my effort to consolidate some of the tags in our wiki, and eliminating the 'attention-needed' category. Most of other 'attention-needed' pages were based on AstroBEAR 1.0 specs, so I moved them over to 'deprecated'.

Finally, an open question for the group: what should go on the visualization page? Most of the visualization tutorials are on the [Tutorials tutorials] page; should they be linked on the visualization page as well? Is there something else entirely that people would like to see there?

Meeting Update for week of July 3, 2011

You've probably already noticed it, but the wiki's front page has been reorganized a bit.

Also, references to /var/trac and /var/repositories have been replaced with /data/trac and /data/repositories, respectively. The two exceptions are:

  • Documentation pertaining to AstroBEAR 1.0.
  • Tickets created prior to the Great Crash of '11.

I'm not sure whether it's worth altering AstroBEAR 1.0 documentation, and I thought I'd get the group's opinion before I start tampering with comments on old tickets.

In other news, the data file tutorials page is now completely filled out. Tutorials now exist for all the major .data files and most of the minor ones (problem.data being the exception).

And in other other news, alfalfa, our new grass-style machine, is online. It doesn't have an Intel compiler installed yet, but it's another 2 TB of storage for people who need it. It is currently only accessible from on campus, unless a VPN is used. A subsequent blog post will have more details.
