Cluster:Todo

(Need a notation for relative priority. Please don't delete anything unless we're updating this during a meeting.)

Plumbing

• Get PBS/Maui working on bazaar, cairo, athena (done), and ACL (done); wiki for usage description, wiki for setup description; node0 exlude lists for startup files or figure-out particular files per machine with SystemImager. Can't get Lori's molecular system to parallelize even outside of PBS/Maui, Josh can give us a pointer to a test suite molecule that will parallelize (Skylar)
• Setup Amanda, follow-up with Dan (Skylar)
  • Move tape drive from admin to hopper
  • Configure Amanda on hopper
• Copy /cluster/old-hopper to tape, give it to charlie (Skylar)
• Fiber uplink for bazaar (Charlie)
• GBIC modules and LACP and port trunking and high latency, contact NetGear
  • Return GBIC module (Alex)
• Put Athena in the display cabinet
  • Cooling
• Setup POVray on Athena
• Protect F@C source and molecular systems, open http, ftp?, ssh? at cluster.earlham.edu (JoshM and Skylar)
  • Protect folding-at-clusters/articles/dr-dobbs
  • Can script find-out (environment variable?) where the checkout went so that it can protect those files?
• Updates to http://cluster.earlham.edu
  • add link to cluster wiki page
  • loose rss feed, leave a single link to mt, last mt entry
  • news - siam posters, bccd.cs.uni.edu, others?
  • General and Resources link sets horizontal instead of vertical.
  • Add link to Resources called documents (add static link to last MT entry and link to wiki)
  • Update weatherduck link
  • Add link to wiki doc under tools
  • Update preset query link
  • Overview and Press prose update (Charlie)
• Update speedup and speedup/efficiency within DVT for endnodes (Alex)

LittleFe

• Test CD/DVD (Alex)
• Before anything else copy node0's drive as it is now and put on Charlie's desk (Toby)
• Setup second board (Alex)
• Setup PXE environment, try run-in-RAM first (Alex and Toby)
• Second disk drive in node1 for redundancy (rsynch from node0) (Alex and Toby)
• Respect Paul's philosophy about setup and usage models, see the other wiki entry (All)
• node0 has script that uses netboot and sequences bootup. (Alex)
• Use a faster drive, 7200RPM, ATA or SATA (Charlie)

Folding@Clusters

• Work with Betsy Ward to get the plumbing for F@C setup on the D224 OSX machines. Local user, document the setup with a Wiki entry. Modify run-fatc.pl, command line option to produce raw SQL. (JoshM and Alex)
• Console (JoshM)
  • Environment variable called $FATCHOME
  • Command line
  • Sockets to communicate with mother
  • Variable in mother.conf for console port
  • Mother listens and responds to commands on the console port
  • Command list: status [(running|paused|stopped), molecular system, x out of y steps completed, estimated time remaining, # nodes started, # of nodes current], checkpoint, pause, resume, stop.
  • Command line option -nn interval for compact, refreshed display.
  • First version of console has to be supplied with a hostname and port number.
  • Future versions (possibly when we introduce the grandmother) can take a $FATCHOME environment variable that points to a mother.conf file (to get a port number) as a discovery mechanism.
    • Can happen now: status(x out of y, stopped or running), stop
    • After mods to mdrun and F@C updates: status(paused, molecular system, estimated time remaining, nodes started, nodes current), pause, resume, checkpoint
  • Give the console the ability to trigger the checkpoint and quit mechanism.
• Checkpointing hook in GROMACS - change mdrun data structures (checkpoint frequency variable) instead of using SIGUSR1, and which files we are using. Figure-out how we can start, checkpoint, and

recover using TPR and TOP files as input (JoshM)

• Develop test canon (Alex and Charlie)
• Document pval_report.pl and compare_walltime.pl (done) in Wiki (headings for each are already under HowTos) (Alex)
• Supervise test runs, non-nfs, a2.7, all molecules, 1-4 nodes, bazaar and cairo, separate table (Alex)
• rerun the following configurations and compare nfs/nonnfs (Alex)
  • bazaar proteasome
  • bazaar villin-urea
  • cairo methanol 1-8 nodes
  • cairo mixed
  • cairo proteasome
  • cairo water 1-8 nodes
  • bazaar water
• Check copyright headers, see Adam's message of March 11, 2005

Curriculum Modules

• Producing a cluster/distro specific set of modules out of one base unit
• Generating a wiki entry and repository entry from one base unit
• Population ecology module, start by finding what packages are available and making a list. (Skylar)

Little-Fe

• Exchange connectors (Alex)
• Try mounting one board (Alex and Charlie)

Green Science

• Track down current and archival weather data (wind, temperature, others) for this area, Muncie airport, RP&L, other sources? (Mary)
• Setup HandyBoard as a way to begin anemometer interfacing (JoshM and Mary)

HIP

• Contact embeddedx86, get price on fixing the board (Alex)
• When we return it ask them to re-init it explaining the bit about the guest account.
• Alex has copies of ~root and other places with our software. At the system level we installed Perl and ssh.
