Authors: Pratul K. Agarwal, Sadaf R. Alam (Oak Ridge National Laboratory) and
Carlos Sosa (IBM)
Abstract:This report describes preliminary benchmarks performance for AMBER v8
on BG/L, as an outcome of Blue Gene applications workshop at Argonne National Lab
(April 27th-28th 2005). Moreover, a number of critical scaling characteristics are
explored in order to scale the computational biology beyond the current limits. Some
issues, which were encountered while compiling and running AMBER v8 on BG/L are
also discussed.

GTC: First experience on Blue Gene/L (pdf)
|
Authors: Stephane Ethier (Princeton Plasma Physics Laboratory)
Abstract: This report describes experiences porting GTC, a 3D gyrokinetic
particle-in-cell (PIC) code in toroidal geometry to
BG/L, as an outcome of Blue Gene applications workshop at Argonne National Lab
(April 27th-28th 2005).

Presentations from the INCITE BG/L workshop
on March 1-2, 2006 at Argonne, Bldg 221 (MCS) in room
216. The workshop was a hands on workshop, provided to the
INCITE project members to help them port their codes quickly
to the BG/L system. Presentations available here:
- BG/L Architecture Overview (Ray Bair).
A basic introduction to the BG/L architecture.
The focus was on the BG/L architecture, the chip,
memory, layout of the system and networks.
- BGL System Introduction (Susan Coghlan)
A basic introduction to the Argonne BG/L System.
The focus was on the configuration, layout, gaining access,
general use and getting help on the Argonne BG/L system BGL.
- BG/L Optimization Tips (Andrew Siegel).
An in-depth discussion of some optimization issues on
the Argonne BG/L System. General CPU info, FMA instructions,
misc notes, data alignment, compiler use and profiling.
- BGW for INCITE (Fred Mintzer - IBM).

Introduction to the Argonne BG/L machine:
Overview, Parallel Issues
and Aspects of single processor optimization
(2005-02-10) pdf
|
Presented by Susan Coghlan, Katherine Riley and Andrew Siegel
on February 10, 2005 at ANL, Bldg 221 (MCS) in room
216. The tutorial consisted of three parts:
- A basic introduction to the Argonne BG/L System.
The focus was on the configuration, layout, gaining access,
general use and getting help on
the Argonne BG/L system BGL.
- A basic introduction to the parallel issues on the MCS
BG/L System. The focus was on the BG/L networks and how
they affect performance, how the OS and resource limitations
affect jobs, using the second CPU, MPI issues, partition
mapping, profiling and debugging.
- An in-depth discussion of some optimization issues on
the Argonne BG/L System. General CPU info, FMA instructions,
misc notes, data alignment, compiler use and profiling.
