Current To-Do

Date represents last meeting where we discussed the item

  • Writeups for Jeff Krause (3/Nov/09)
  • Brad's Graphing Tool (19/Oct/09)
 * 2 y-axis scales (runtime and problem size)
 * error bars for left and right y-axes with checkboxes for each
 * eps file for the poster
  • TeraGrid Runs (1/Dec/09)
 * Check new GalaxSee on BobSCEd
 * Update configure.ac based on Fitz's notes from Kraken
 * Status on pople?
 * Remember Big Red has a debug queue
 * GalaxSee -- after stats changes, GalaxSee slowed down by a lot.
   * Double check on BobSCEd, find the algorithm problem
  • New LittleFe Boards (19/Oct/09)
  • New cluster (9/Dec/09)
 * Better to not spend $$$ on next-day business response.  Losing a node is not a big deal.
 * BobSCEd already has IB.  Any value to having CUDA and IB in the same nodes?
  • BCCD Testing (9/Dec/09)
 * Get Fitz's liberation instructions into wiki
 * Get Kevin's VirtualBox instructions into wiki
 * pxe booting -- see if they booted, if you can ssh to them, if the run matrix works 
 * Test all boot options
 * CUDA LittleFe is now online -- test CUDA boot options
 * Send /etc/bccd-revision with each email
 * Send output of netstat -rn and /sbin/ifconfig -a with each email
 * Run Matrix
 * For the future:  scripts to boot & change bios, watchdog timer, 'test' mode in bccd, send emails about errors

Summer of Fun (2009)

An external doc for GalaxSee
Documentation for OpenSim GalaxSee

What's in the database?

GalaxSee (MPI) area-under-curve (MPI, openmpi) area-under-curve (Hybrid, openmpi)
acl0-5 bs0-5 GigE bs0-5 IB acl0-5 bs0-5 GigE bs0-5 IB acl0-5 bs0-5 GigE bs0-5 IB
np X-XX 2-20 2-48 2-48 2-12 2-48 2-48 2-20 2-48 2-48

What works so far? B = builds, R = runs, W = works

To Do

  • Fitz/Charlie's message
  • Petascale review
  • BobSCEd stress test

Implementations of area under the curve

  • Serial
  • OpenMP (shared)
  • MPI (message passing)
  • MPI (hybrid mp and shared)
  • OpenMP + MPI (hybrid)

GalaxSee Goals

  • Good piece of code, serves as teaching example for n-body problems in petascale.
  • Dials, knobs, etc. in place to easily control how work is distributed when running in parallel.
  • Architecture generally supports hybrid model running on large-scale constellations.
  • Produces runtime data that enables nice comparisons across multiple resources (scaling, speedup, efficiency).
  • Render in BCCD, metaverse, and /dev/null environments.
  • Serial version
  • Improve performance on math?

GalaxSee - scale to petascale with MPI and OpenMP hybrid.

  • GalaxSee - render in-world and steer from in-world.
  • Area under a curve - serial, MPI, and OpenMP implementations.
  • OpenMPI - testing, performance.
  • Start May 11th

LittleFe

  • Testing
  • Documentation
  • Touch screen interface

Notes from May 21, 2009 Review

  • Combined Makefiles with defines to build on a particular platform
  • Write a driver script for GalaxSee ala the area under the curve script, consider combining
  • Schema
    • date, program_name, program_version, style, command line, compute_resource, NP, wall_time
  • Document the process from start to finish
  • Consider how we might iterate over e.g. number of stars, number of segments, etc.
  • Command line option to stat.pl that provides a Torque wrapper for the scripts.
  • Lint all code, consistent formatting
  • Install latest and greatest Intel compiler in /cluster/bobsced

BobSCEd Upgrade

Build a new image for BobSCEd:

  1. One of the Suse versions supported for Gaussian09 on EM64T [v11.1] - Red Hat Enterprise Linux 5.3; SuSE Linux 9.3, 10.3, 11.1; or SuSE Linux Enterprise 10 (see G09 platform list) <-- CentOS 5.3 runs Gaussian binaries for RHEL ok
  2. Firmware update?
  3. C3 tools and configuration [v4.0.1]
  4. Ganglia and configuration [v3.1.2]
  5. PBS and configuration [v2.3.16]
  6. /cluster/bobsced local to bs0
  7. /cluster/... passed-through to compute nodes
  8. Large local scratch space on each node
  9. Gaussian09
  10. WebMO and configuration [v9.1] - Gamess, Gaussian, Mopac, Tinker
  11. Infiniband and configuration
  12. GNU toolchain with OpenMPI and MPICH [GCC v4.4.0], [OpenMPI v1.3.2] [MPICH v1.2.7p1]
  13. Intel toolchain with OpenMPI and native libraries
  14. Sage with do-dads (see Charlie)
  15. Systemimager for the client nodes?

Installed:

Fix the broken nodes.
