Japan Aerospace Exploration Agency (JAXA) has long recognized the importance of numerical simulations using high performance computer and has strongly promoted the installation and operation of large scale high performance computing system. Since Oct. 2002, JAXA had operated an SMP-cluster type large scale parallel computing system, called NS-III. In April 2009, it was replaced with a multicore based scalable parallel cluster with approximately 12,000 cores, peak performance of 120 Tflops and 94 TBytes of main memory. The new system is called JAXA Supercomputer System (JSS). In this paper, after reviewing the overview of the newly installed system and parallel programming model on the new system, we present the results of preliminary performance evaluation for our current aerospace CFD applications as well as Linpack HPL on JSS.
