I am a graduate student in computer science at The Ohio State
University. Before coming to OSU I earned my BS in Computer
Engineering from UMass, Amherst and
was a member of the Architecture
and Language Implementation Lab. I am also an officer in OSU's
Open Source Club and
a representative on the graduate steering committee.
My advisor is Professor Sadayappan
and I am a member of the High Performance Computing
Research Laboratory. My work at OSU focuses on task parallelism,
dynamic load balancing, and the programming models and scalable runtime
systems needed to efficiently use task parallelism on modern HPC
systems. My research interests include parallel programming models,
scalable runtime systems, fault tolerance, high performance computing
applications, and computer architecture.
I'm out of town right now on internship at Argonne National Laboratory in Illinois. I'll be back at OSU in the summer.

Dynamic SimpleScalar and DSSWattch
DSSWattch: Power Estimation in Dynamic SimpleScalar
[pdf]
James Dinan, Eliot Moss. Technical Report; UMass ALI Lab. Amherst, MA.
Dynamic SimpleScalar is an extended version of
the SimpleScalar architectural simulator that extends support
for PowerPC targets to PPC/AIX, PPC/Linux, and PPC/OS-X. With DSSWattch, we have
adapted Wattch's
power modelling extensions to DSS's updated framework and PPC microarchitecture.

Scioto: Shared collections of task objects
Scioto is a runtime system to support task parallelism on distributed memory clusters. It is
designed to interoperate with Partitioned Global Address Space (PGAS) programming models as well
as other popular tools such as MPI. Project Homepage.
RAPC Tool (v0.3)
RAPC is a little BASH script to help people connect to the rapc machines. You'll also need to have
html2text
installed on your machine - most popular linux distros should have a package for it.
