Dr. Yi Pan – CS Fall 2016 Colloquium Speaker

November 4th, 2016 the Computer Science Department will be having a Computer Science Department Colloquium talk located in ECS South 2.410 from 11:00am to 12:00pm. The speaker is Dr. Yi Pan, Regents’ Professor of Computer Science, Interim Associate Dean and Chair of Biology, Georgia State University.

Abstract

Cloud computing has gradually evolved into an infrastructural tool for many scientific and business applications with intensive data or computing requirements. One of the challenges in cloud computing now is how to run software efficiently on cloud platforms since lots of classic codes are not capable of being executed in parallel in cloud environments, resulting in low efficiency. It is also costly to redesign and convert current sequential codes into cloud codes on cloud programming models such as MapReduce or Spark. Thus, automatic translation from sequential codes to cloud codes is one of the directions that could resolve the problem of slow code migration from traditional computing platforms to cloud infrastructures. In this talk, I will present several automatic translators (M2M, J2M and J2S) for cloud programming models MapReduce and Spark. I will provide details of the design of our translators and their performance results through experiments. Comparisons with hand coded cloud programs will also be studied. Our experimental results indicate that the translators not only can precisely translate the sequential Java into cloud codes, but also can achieve almost linear speedup in performance if the data are big enough. In addition, their limitations and shortcomings will also be identified and future directions in this area will be provided.
