Projects:
1. Numerical Linear Algebra Algorithms and Software
a. LAPACK, ScaLAPACK, ATLAS
b. Self Adapting Numerical Algorithms (SANS) Effort
c. Generic Code Optimization
d. LAPACK For Clusters – easy access to clusters
2. Heterogeneous Distributed Computing
a. NetSolve, FT-MPI, Open-MPI
3. Performance Evaluation
a. PAPI, HPC Challenge, Top500
4. Software Repositories
a. Netlib
LAPACK
1. Used by Matlab, Mathematica, Numeric Python,…
2. Tuned version provided by vendors: AMD, Apple, Compaq, Cray, Fujitsu, Hewlett-Packard, Hitachi, IBM, Intel, MathWorks, NAG, NEC, PGI, SUN, Visual Numerics, by Microsoft and most of Linux distribution (Fedora, Debian, Cygwin,...).
3. On going work: performance, accuracy, extended precision, ease of use
ScaLAPACK
1. Parallel implementation of LAPACK scaling on parallel hardware from 10’s to 100’s to 1000’s of processors
2. On going work: Match functionalities of current LAPACK
3. On going work: Target new architectures, new parallel environment. For example port to Microsoft HPC cluster solution
LAPACK for Clusters (LFC)
1. Most of ScaLAPACK functionality from serial clients (Matlab, Python, Mathematica)
FT-MPI and Open-MPI
1. Define the behavior of MPI in event a failure occurs at the process level.
2. FT-MPI based on MPI 1.3 (plus some MPI 2 features) with a fault tolerant model similar to what was done in PVM.
3. Complete reimplementation, not based on other implementations.
a. Gives the application the possibility to recover from a process-failure.
b. A regular, non fault-tolerant MPI program will run using FT-MPI.
c. What FT-MPI does not do:
4. Recover user data (e.g. automatic check-pointing)
5. Provide transparent fault-tolerance
Performance Application Programming Interface (PAPI)
1. A portable library to access hardware counters found on processors
2. Provides a standardized list of performance metrics
KOJAK (Joint with Felix Wolf)
1. Software package for the automatic performance analysis of parallel apps
2. Message passing and multi-threading (MPI and/or OpenMP)
3. Parallel performance
4. CPU and memory performance
