#  cd into the directory and run ./configure --with-mpi --with-openmp

#  Use stat.pl and args_man to make an appropriate statistics run.  See args_man for a description of predicates.  Example:

Al-Salam/CCG Downtime tasks

  • LDAP Server migration from bs-new -> hopper
  • yum update over all nodes
  • Turn HT off

  • PBS server on Hopper

How to use the PetaKit

  1. If you do not already have it, obtain the source for the PetaKit from the CVS repository on hopper (curriculum-modules/PetaKit).
  2. cd to the Subkits directory of PetaKit and run the area-subkit.sh to make an area subkit tarball or GalaxSee-subkit.sh to make a GalaxSee subkit tarball.
  3. scp the tarball to the target resource and unpack it.
  4. cd into the directory and run ./configure --with-mpi --with-openmp
  5. Use stat.pl and args_man to make an appropriate statistics run. See args_man for a description of predicates. Example:
perl -w stat.pl --program area --style serial,mpi,openmp,hybrid --scheduler lsf --user leemasa --problem_size 200000000000
--processes 1,2,3,4,5,6,7,8-16-64 --repetitions 10 -m -tag Sooner-strongest-newest --mpirun mpirun.lsf --ppn 8

10,000 foot view of problems

Parent Process Sends Out Children Send Back Results Compiled By
Area function, bounds, segment size or count sum of area for specified bounds sum
GalaxSee complete array of stars, bounds (which stars to compute) an array containing the computed stars construct a new array of stars and repeat for next time step
Matrix x Matrix n rows from Matrix A and n columns from Matrix B, location of rows and cols n resulting matrix position values, their location in results matrix construct new result array

Visualizing Parallel Framework

http://cs.earlham.edu/~carrick/parallel/parallelism-approaches.png

Parallel Problem Space

  • Dwarf (algorithm family)
  • Style of parallelism (shared, distributed, GPGPU, hybrid)
  • Tiling (mapping problem to work units to workers)
  • Distribution algorithm (getting work units to workers)

Summer of Fun (2009)

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.
