Silvius Rus - Research
Summer 2002, Internship
at the
Thomas J. Watson IBM Research Center,
within the BlueGene software team led by
Jose Moreira.
My mentor was Gheorghe Almasi.
I worked there on the design and implementation of the MPI
(Message Passing Interface) for
BlueGene/L,
in collaboration with the MPICH 2.0 team at
Argonne National Laboratory.
My part in the project consisted in designing and implementing basic MPI functionality by adapting an existent MPICH 2.0 TCP-based implementation to the performant but complex interprocessor communication network of the BlueGene/L parallel architecture.
I implemented the specifications of the MPICH generic basic send/receive interface using native BlueGene/L communication primitives. This resulted in functional MPI point-to-point communication capabilities, which in turn led to functional collective communication. I also ported a basic version of the MPD job startup mechanism.
By the end of my internship term we had achieved a functional MPI implementation for BlueGene/L.
