Concurrent Object-oriented Programming Languages (OOPL)


An efficient implementation scheme of concurrent object-oriented languages on stock multicomputers

This paper aims to implement high performance OOPL on conventional multicomputers.

Highly-tuned Hardware & Specially tailored Software

Two key factors in high-performance concurrent OOPL and their hardware assisted solutions:

  1. Efficient Message Passing: processors and the network are tightly connected.
  2. Efficient intra-node multithreading: the hardware manages the scheduling queue and the next runnable thread is scheduled automatically upon termination of the current thread.
