Sommario/riassunto |
|
XcalableMP is a directive-based parallel programming language based on Fortran and C, supporting a Partitioned Global Address Space (PGAS) model for distributed memory parallel systems. This open access book presents XcalableMP language from its programming model and basic concept to the experience and performance of applications described in XcalableMP. XcalableMP was taken as a parallel programming language project in the FLAGSHIP 2020 project, which was to develop the Japanese flagship supercomputer, Fugaku, for improving the productivity of parallel programing. XcalableMP is now available on Fugaku and its performance is enhanced by the Fugaku interconnect, Tofu-D. The global-view programming model of XcalableMP, inherited |

from High-Performance Fortran (HPF), provides an easy and useful solution to parallelize data-parallel programs with directives for distributed global array and work distribution and shadow communication. The local-view programming adopts coarray notation from Coarray Fortran (CAF) to describe explicit communication in a PGAS model. The language specification was designed and proposed by the XcalableMP Specification Working Group organized in the PC Consortium, Japan. The Omni XcalableMP compiler is a production-level reference implementation of XcalableMP compiler for C and Fortran 2008, developed by RIKEN CCS and the University of Tsukuba. The performance of the XcalableMP program was used in the Fugaku as well as the K computer. A performance study showed that XcalableMP enables a scalable performance comparable to the message passing interface (MPI) version with a clean and easy-to-understand programming style requiring little effort. |

Sommario/riassunto |
|
In September 1930, the New York Times published a list of the clergy whom Rabbi Stephen Wise considered "the ten foremost religious leaders in this country." The list included nine Christians and Rabbi Henry Cohen of Galveston, Texas. Little-known today, Henry Cohen was a rabbi to be reckoned with, a man Woodrow Wilson called "the foremost citizen of Texas" who also impressed the likes of William Howard Taft and Clarence Darrow. Cohen's fleeting fame, however, was built not on powerful friendships but on a lifetime of service to needy Jews—as well as gentiles—in London, South Africa, Jamaica, and, for the last sixty-four years of his life, Galveston, Texas. More than 10,000 Jews, mostly from Eastern Europe, arrived in Galveston in the early twentieth century. Rabbi Cohen greeted many of the new arrivals in Yiddish, then helped them find jobs through a network that extended throughout the Southwest and Midwest United States. The "Galveston Movement," along with Cohen's pioneering work reforming Texas prisons and fighting the Ku Klux Klan, made the rabbi a legend in his time. As this portrait shows, however, he was also a lovable mensch to his grandson. Rabbi Henry Cohen II reminisces about his grandfather's jokes while placing the legendary rabbi in historical context, creating the best picture yet of this important Texan, a man perhaps best summarized by Rabbi Wise in the New York Times as "a soul who touches and kindles souls." |
