integrated software infrastructure built on the
MPI_T interface which defines the API for
interaction and information interchange to enable
fine grained performance optimizations for HPC
applications. The challenges addressed by the
project include: 1) enhancing existing support for
MPI_T in MVAPICH to expose a richer set of
performance and control variables; 2) redesigning
TAU to take advantage of the new MPI_T variables
exposed by MVAPICH; 3) extending and enhancing TAU
and MVAPICH with the ability to generate
recommendations and performance engineering
reports; 4) proposing fundamental design changes
to make MPI libraries like MVAPICH
"reconfigurable" at runtime; and 5) adding support
to MVAPICH and TAU for interactive performance
engineering sessions.
