%X Itanium is the first generation product processor based on IA-64 architecture. ORCCOpen Research Compiler) provides an open source IPF(Itanium Processor Family)research compiler infrastructure. We have compiled and run NAS Benchmarks on the Itanium machine. This paper briefly describes the performance of orcc, sgicc and gcc in the following 3 ways : execution time, compilation time, and executable file size. The results show that orcc has nearly the same performance as sgicc, which is 2 fold faster over gcc in the aspect of execution time. We also find that even with the best-optimized program, the utilization ratio of process resources is no more that 70%.
