Parallel and Distributed Computing for Real-time Analytics

我的研究目标是创建一个运行时系统，该系统可以扩展到大型多核机器集群，用于大数据分析的内存计算。许多现有的分布式系统没有利用高性能计算中开发的工具和技术来解决最终限制可伸缩性的性能问题。MPI（消息传递接口）是一个消息传递库，它是用于高性能计算的并行编程中的事实上的标准。我打算开发新的MPI中间件以及相关的工具，作为计算分析的可伸缩运行时系统的基础。

The goal of my research is to create a runtime system that can scale-out to large size clusters of multicore machines for in-memory computation of analytics on big data. Many of the existing distributed systems do not take advantage of the tools and techniques developed in high performance computing for addressing the performance issues that ultimately limits scalability. MPI (Message-Passing Interface) is a message-passing library that is the de-facto standard in parallel programming for high performance computing. I intend to develop new MPI middleware along with associated tools as the basis for a scalable runtime system for computing analytics. Scaling-out requires the ability to express massive amounts of concurrency and ultimately relies on message-passing. As such, the starting point for this work will be our FG-MPI (Fine-Grain MPI (Message-Passing Interface)) system, which we have shown can scale to thousands and millions of processes. FG-MPI extends MPICH, an MPI runtime system that is used to derive most of the commercial versions of MPI. This work will require extending the existing FG-MPI middleware as well as introducing new tools and techniques for programming at large scale. The research involves (a) investigating further improvements to the MPI middleware to support multicore machines, (b) developing tools to support an "actor-like" programming environment for specifying the composition of processes and the development of service-oriented data structures for MPI, (c) following a million process methodology to develop techniques for developing and deploying programs at scale, (d) developing innovative message-based data structures and algorithms to support knowledge-based analysis and reasoning on big data. This research directly addresses the two main trends in computer technology: the appearance of multicore and cluster/cloud computing. In both cases --- the future is parallel! The central problem is how to use multicore to scale-up or how to use more machines to scale-out to provide the performance needed to process and compute analytics on the vast amount of data that is available today.
