Abstract
The e-language is a simple parallel extension of c for a class of
emulated shared memory multiprocessor systems on chip (W-SOC). It provides an
easy-to-use access to fine-grained parallel programming and exploitation of
architectural techniques for that class. Unfortunately, the initial
implementation of e introduced quite high parallel construct execution time
overheads and was strongly tied to exclusive read exclusive write (EREW)
memory access model. In this paper we describe faster implementation of e
supporting the latest architectural advances in MP-SOCs realizing the
multioperation concurrent read concurrent write (MCRCW) model and fast barrier
synchronizations. According to our evaluation the new fast mode in together
with the stronger computational model provides a significant boost in parallel
construct performance for simple e-programs.
