Chu Jong |
expected completion: May 2001 |
Dissertation title: Scalability Issues in the Development of
Tools for Massively Parallel Systems.
Chu's dissertation addresses the development
of support tools for debugging and performance
tuning of massively parallel applications.
Chu passed his proposal defense in January
1998.

Rolf Riesen |
expected completion: December 2001 |
Dissertation title: Using Kernel Extensions to Decrease the Latency
of User-Level Communication Primitives.
Rolf works at Sandia National Labs where
he is the technical lead on the C-plant project.
His dissertation addresses approaches to
kernel extensibility from the perspective
of high performance, massively parallel machines.
Rolf's proposal is available in html and postscript.
Rolf passed his proposal defense in September
1996.

Patricia Gilfeather |
expected completion: May 2002 |
Patricia is looking at high-performance implementations
of commodity prtocols, i.e., TCP/IP. Along
with Todd Underwood (see MS students below),
she has developed an implementation of IP
for Gigabit Ethernet that offloads fragmentation
and reassembly to the NIC. This implementation
achieves high bandwith with low and predictable
latency while greatly reducing CPU utilization.
Patricia passed her general exams in January
2001.

Gabriela Barrantes |
expected completion: May 2003 |
Gabriela is attending UNM on a Fullbright
scholarship. This semester, she's mostly
taking classes preparing for the comprehensive
exams. Gabriela is also doing some background
research looking into reliable transmission
protocols for highly reliable networks.
Gabriela is planning to take the general
exams in August 2001.

Ron Brightwell |
expected completion: May 2003 |
Ron has an MS degree from Mississippi State
and has just started in the PhD program at
UNM. Right now, he's taking courses getting
ready to take the comprehensive exams. Like
Rolf, Ron works at Sandoa National Labs on
the C-plant project. We used to call Ron
"the MPI guy," but lately it seems
like he's doing a lot more than MPI implementations.
Ron is planning to take the general exams
in January 2002.

Jared Dreicer |
expected completion: ??? |
Jared's proposal is titled Theory Development for Sensor Deception Analysis. His dissertation will address the development
of a theory of deception from remote,
embedded
sensors.
Jared defended his proposal in May 1998.

MS students
Todd Underwood |
expected completion: May 2001 |
Thesis tile: Improving IP Performance by Offloading Fragmentation
and Reassembly
Along with Particia Gilfeather (see PhD students),
Todd has implemented a NIC control program
that offloads IP fragmentation and reassembly
from the host processor. This implementation
achieves bandwidths comparable to the standard
implementation (990 Mb/s) while reducing
the CPU uitlization from 80% to 40% as measured
by netperf.
Todd defended his MS thesis proposal in September
2000.

Edgar Leon-Borja |
expected completion: December 2001 |
Thesis title: Measuring the Impact of Varying Communication
Overhead on Application Performance
Edgar is currently working as a student intern
at Intel in Santa Clara, but is still running
tests remotely.
Edgar has modified a version of GM so that
he can vary communication timing parameters
(e.g., host processor overhead and latency).
He has also ported several of the NCSA community
codes to run on a small cluster that uses
his modified GM drivers.

Wenbin Zhu |
expected completion: May 2002 |
Thesis title: An Implementation of Portals 3.0 on Gigabit
Ethernet
Wenbin is writing a control program to implement
Portals 3.0 on the Alteon ACE Nics.
|
Bill Lawry |
expected completion: December 2002 |
Bill just started working in the group and
is presently looking for a thesis topic.
|
Undergraduate Students
Dena Vigil |
expected graduation: May 2001 |
Dena is developing a test suite for Portals
3.0.
|
Riley Wilson |
expected graduation: December 2001 |
Riley is working on collecting and developing
performance evaluation tools.

PhD Students
Philip Campbell |
March 1997 |
Using Execution Disciplines to Speed-up Computer
Programs
Phil used PDW constructs to examine execution
variability under control-driven, data-driven,
and demand-driven executions.
|
Francisco Reverbel |
May 1996 |
Persistence in Distributed Object Systems:
ORB/ODBMS Integration
Francisco spent most of his time at
Los Alamos
National Labs where he worked on the
Sunrise/Telemed
project. Check out Francisco's home
page,
it has links to the project's he's
involved
in.
Francisco is back in Brazil now, working
as an Assistant Professor in the Department
of Computer Science at the University
of
Sao Paulo in Brazil.

Ksheerabdhi Krishna |
December 1994 |
Representing and Extracting Program Dependences
When Krishna finished his degree, he went
to work for (what used to be) Cray Research
in Santa Fe. After spending his first year
working on the final version of Cray's Pascal
compiler, it looked like Krishna would finally
get a chance to start working on program
dependence again. Then he decided that SGI/Cray
wasn't for him anymore.
Krishna is now working on smart cards for
Schlumberger in Austin, Texas.

Stephen Wheat |
November 1992 |
A Fine Grained Data Migration Approach to
Application Load Balancing on MP MIMD Machines
Stephen is now employed at Intel in Chandler
AZ.
In August of 1995, Stephen was named outstanding
alumnus of the CS department at UNM. In December
of 1994, Stephen lead the group that set
the world record (281 Gflops on MPLINPAK,
and 328 Gflops on an LU factorization code).
Stephen was also a member of the team that
won the 1994 Gordon Bell Award.
