HPC Challenge Awards
The HPC Challenge benchmarks are benchmark programs designed to evaluate the overall performance of supercomputers in terms of processing performance in 28 tests derived from frequently used computational patterns in the field of scientific computation. The HPC Challenge Awards are evaluated based on the HPC Challenge benchmarks. There are two classes of awards: Class 1, which measures benchmark performance values, and Class 2, which measures the productivity of programming language implementations. The Class 1 awards consist of the following four benchmarks, each of which evaluates the performance of key system components (CPU computational performance, memory access performance, network transmission performance).
- Global HPL: operating speed in solving large-scale simultaneous linear equations
- EP STREAM (Triad) per system: memory access speed under multiple loads
- Global FFT: total performance of Fast Fourier Transform
- Global RandomAccess: random memory access performance in parallel processing
HPC Challenge Class 2 Awards are given to programming languages used for developing HPC applications. Three benchmarks are selected from the four used in the Class 1 category, and both the productivity of the programming language and benchmark performance are evaluated for the implementation of these benchmarks. In addition, participants can choose to include up to two additional benchmarks besides the HPC Challenge benchmarks for consideration, and the award is determined based on the total score for the implementations including the additional benchmarks of Best Performance and Most Elegant Language or Most Elegant Implementation.
 K computer
The K computer, which was jointly developed by RIKEN and Fujitsu, is part of the High-Performance Computing Infrastructure (HPCI) initiative led by Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT). The K computer's availability for shared use began in September 2012. The "K" in K computer comes from the Japanese Kanji character "Kei" which means ten peta or 10 to the 16th power. In its original sense, "Kei" expresses a large gateway, and it is hoped that the system will be a new gateway to computational science.
A programming language that facilitates the development of parallel applications that run on supercomputers and other large-scale computational environments. With XcalableMP, it is possible to develop parallel applications that can achieve the same computational speeds as existing methods while using comparatively shorter code.
A programming language that is an extension of XcalableMP and OpenACC, the standard language for programming for accelerators. In addition to the conventional XcalableMP structure, it has a structure in which communication is conducted between accelerators, making it easy to develop applications that run on parallel computers that are equipped with accelerators. Development of the XcalableACC was supported by the JST/CREST program entitled "Research and Development on Unified Environment of Accelerated Computing and Interconnection for Post-Petascale Era" in the research area of "Development of System Software Technologies for Post-Peta Scale High Performance Computing."
A supercomputer developed by the University of Tsukuba that is equipped with a GPU (Graphics Processing Unit) accelerator, which is the most representative type of accelerator. In the Green500 contest, which ranks supercomputers by how efficiently they can compute using the least amount of electrical power, HA-PACS ranked third in the world (as of June 2014) for its Tightly Coupled Accelerators (TCA).
RIKEN is Japan's flagship research institute devoted to basic and applied research.
