This paper provides a discussion on the shortcomings of traditional static optimization techniques when used in the context of many-core architectures. We argue that these shortcomings are a result of the significantly different environment found in many-cores. We analyze previous attempts at optimization of Dense Matrix Multiplication (DMM) that failed ...

Computing systems have reached the performance limits attainable by increasing clock rates and complexity, and are now using increased thread-level parallelism and heterogeneity instead. Existing software typically deals poorly with large-scale or heterogeneous computer systems, relying on multiple poorly interacting or special-purpose software interfaces to approach scaling/heterogeneity; attempting to use ...

Advanced many-core CPU chips already have a few hundreds of processing cores (e.g., 160 cores in an IBM Cyclops-64 chip) and more and more processing cores become available as computer architecture progresses. The underlying runtime systems of such architectures need to efficiently serve hundreds of processors at the same time, ...

October 2011 DFM '11: Proceedings of the 2011 First Workshop on Data-Flow Execution Models for Extreme Scale Computing
Publisher: IEEE Computer Society
Citation Count: 8

The many-core revolution brought forward by recent advances in computer architecture has created immense challenges in the writing of parallel programs for High Performance Computing (HPC). Development of parallel HPC programs remains an art, and a universaldoctrine for synchronization, scheduling and execution in general has not been found for many-core/multi-core ...

August 2010 Euro-Par'10: Proceedings of the 16th international Euro-Par conference on Parallel processing: Part II
Publisher: Springer-Verlag
Citation Count: 7

Traditional parallel programming methodologies for improving performance assume cache-based parallel systems. However, new architectures, like the IBM Cyclops-64 (C64), belong to a new set of many-core-on-a-chip systems with a software managed memory hierarchy. New programming and compiling methodologies are required to fully exploit the potential of this new class of ...
