Computing Resources & Local Machines

Noticed as I am scp-ing data on the CollidingFlows runs that some of the typical machines I used are starting to become full. I also do visualizations on Clover or my own machine, however they can be quite hard on my own graphics card. This has led to talk to Baowei and others about potentially looking into developing a new machine quote (see: https://astrobear.pas.rochester.edu/trac/blog/bliu02072012).

Given that the quote is 6 months old, that the price is not the same anymore. It has been suggested to me that someone in the group should e-mail Sean Kesavan <sean@asacomputers.com> and ask him to give up an updated quote or change it to meet our requirements (referencing the quote number on the quotation). I also think these are the specs for Bamboo (https://www.pas.rochester.edu/~bliu/ComputingResources/ASA_Computers.pdf).

In my opinion it might be a good idea to look into more disk space/storage and also get a new machine for visualization. In the mean time I took a look at our local machines and who is using them.

Commands I am using:

*du -sh * 2>&1 | grep -v "du: cannot" prints the disk spaced used for each user by printing standard error to standard out.

*df -h inside of the directory to see disk spaced used (along with %) and space that is available.

Meeting update - Week of July 18, 2011

The Building AstroBEAR page has been updated to reflect VPN changes brought about by the Great Crash. There is also a new section with instructions for building AstroBEAR on alfalfa.

Speaking of which, the RAID setup on alfalfa is being reconfigured to allow us access to the full 5 TB (this gives us RAID 1).

Some preliminary edits have been made to the Debugging Meeting page to make it clearer which tickets are covered by which reports. I'm still working with Rich to get the TicketCharts macro up and running again (which will restore pie graphs to the debug meeting page).

I'm currently looking over the draft of the AstroBEAR 2.0 paper.

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?
