Performance Characteristics of Dual-Processor HPC Cluster Nodes Based on 64-Bit Commodity Processors

Tags:
processors

Overview Dual-processor nodes are the preferred building blocks in HPC clusters because of the greater performance-to-price ratio of such configurations relative to clusters comprising single-processor nodes. The arrival of 64-bit commodity clusters for HPC is advantageous for large space applications that require memory and I/O addressing beyond the 32-bit support. Some of these 64-bit processors also use more advanced memory subsystems, which provide increased performance for some applications. This paper examines the overall performance characteristics of three dual-processor systems based on commodity 64-bit processors: Intel Itanium2, AMD Opteron and IBM PowerPC 970, also known as the Apple PowerPC G5.
