Title: DASH Performance and Usability Comparison to Chapel, Cilk, Go and TBB
Abstract:
Since about thirty years parallel systems are on the rise and parallel programming
systems along with it. But the hardware environments are diverse and s difficult to
find a good parallel programming system that gives access to high level abstractions,
which enable to be expressive with only a few lines of code, and are portable and efficient
too. A previous work compared the four parallel programming systems Chapel, Cilk,
Go and TBB for usability and performance by implementing the so called Cowichan
problems. An introduction to these four parallel programming systems will be provided.
We will also present the Cowichan problems used in the previous work and use the latter
as a template, like their authors suggested. Therefore we implemented the Cowichan
problems in DASH and compared the metrics lines of code, execution time and speedup
to measure usability and performance on a shared memory system. A summary of
the implementations and their differences will be provided. Since DASH is originally
designed for distributed systems, a scaling investigation on the SuperMUC system is
done too.
