João Fellipe Uller presented his work entitled Enhancing Programmability in NoC-Based Lightweight Manycore Processors with a Portable MPI Library at the Simpósio em Sistemas Computacionais de Alto Desempenho (WSCAD), which was held virtually this year due to the COVID-19 pandemic. This work was advised by Prof. Márcio Castro.
In this work, João proposed a portable and lightweight MPI library (LWMPI) designed from scratch to cope with restrictions and intricacies of lightweight manycores. This library was integrated into a distributed OS that targets these processors and evaluated it on the Kalray MPPA-256 processor. Results obtained with three applications from a representative benchmark suite unveiled that LWMPI achieves similar performance scalability in comparison with the low-level vendor-specific API narrowed for MPPA-256, while exposing a richer programming interface.
