Ashish Agarwal commented on HAMA-367:
-------------------------------------
Hi,
I did some research
- looked at the paper above
- read chapter 1 of the book Parallel Scientific Computing - A structured
approach ... by R.H.Bisseling
- looked at the paper "Adaptive-Compi: Enhancing Mpi-Based Applications’
Performance and Scalability by using Adaptive Compression"
and some online tutorials about MPI.
In the project, we would be looking at two areas -
1. Study different compression algorithms and implement the ones that are able
to exploit the unique characteristics of MPI messages.
2. Develop an adaptive compression algorithm - where we could first identify
the datatype of the file that is to be compressed and then use the appropriate
compression.
Thanks
Ashish

> 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.
