UPC is an explicit parallel extension of ANSI C, which has been gaining rising attention from vendors and users. In this work, we consider the low-level monitoring and experimental performance evaluation of a new implementation of the UPC compiler on the SGI Origin family of NUMA architectures. These systems offer many opportunities for the high-performance(More)
We experiment with various techniques of monitoring and tuning UPC programs while porting NAS NPB benchmark using the recently developed GCC-SGI UPC compiler on the Origin O3800 NUMA machine. The performance of the NAS NPB on the SGI NUMA environment is compared to previous NAS NPB statistics on a Compaq multiprocessor. In fact, the SGI NUMA environment has(More)
