Edward J. Yoon commented on HAMA-367:
-------------------------------------
Hi,
Here's very nice paper:
http://www.civ.cvut.cz/others/konference_supercomputing/Proceedings_SC_2004/schedule/pdfs/pap183.pdf
The goal of this project also is a "the compression algorithm that allows
-cMPI- to make better use of available network bandwidth, and several
performance-enhancing optimizations."
As mentioned in paper, the use of *suitable compression algorithm for message
data type* can significantly affect the system performance.
First of all, you will need to design your own scenario. (1. Why) If you want
to improve the performance of exist examples (e.g., Pi Estimator), it's OK. and
then, implement the compression. (2. What/How) Finally, proof your work. (3.
Benchmark and Conclusion)
Your code can be improved later. Don't waste your time to writing beautiful
code. *The introduction, development, turn and conclusion are important. :)

> As you know, the exchanging data between processes, is a core part of whole
> performance in Bulk Synchronous Parallel.
> In this research, we investigate BSP message data compression in the context
> of large-scale distributed message-passing systems to reduce the
> communication time of individual messages and to improve the bandwidth of the
> overall system.
