=== Title ===
Fusion Optimizations in Parallel Skeleton Libraries –Towards Reliable Parallel Programming
=== Abstract ===
Parallel programming is difficult. However, it is now an essential task for programmers. This situation calls for a methodology for reliable concise parallel programming. To challenge the problem, we have intensively studied “skeletal parallel programming”, in which programmers easily develop parallel programs by composing ready-made parallel program components called skeletons. Moreover, their naively-composed skeleton programs can be optimized via fusion transformations to achieve efficient execution. In this presentation, focusing on the optimization on parallel skeletons, we will introduce a basic theory of our parallel skeletons and their optimizations briefly, and see their implementation in our SkeTo library (C++) and GoG library (Fortress).

=== Title ===
Design of a DSL by Ruby for heavy computations over map-reduce clusters
=== Abstract ===
Recently parallel distributed computing for massive data is easier than ever before because of map-reduce technologies, but we still have difficulties to implement the map-reduce code description efficiently as a general level engineer.
“Hadoop papyrus”, which I created as open source software, enables us to describe map-reduce procedure running on Hadoop not Java language but Ruby which is efficient and flexible programming language.
Furthermore it is designed as DSL framework which can describe for a domain specifically.
I will present how map-reduce procedure can be changed into DSL mainly.
