[52] pp.; 21 x 24 cm.; sewn bound; black-and-white; edition size unkown; unsigned and unnumbered; offset-printed Two volume exhibition catalogue published in conjunction with two-part show held March 14 ? May 18, 2014 and May 25 ? August 3. "Other Primary Structures revisited the premise of and built upon the Museum''s seminal 1…966 exhibition Primary Structures: Younger American and British Sculptors, the first American museum exhibition to survey the style now known as Minimalism. Primary Structures introduced the public to such artists as Carl Andre, Dan Flavin, Donald Judd, Sol LeWitt, Walter De Maria, Robert Morris, and others--figures unknown at the time but soon to become synonymous with a radically new approach to sculpture. Nearly 50 years later, Other Primary Structures revisits this formative moment in art history while also reexamining the period from today''s far more global perspective. "Presented in two parts, the first part of the exhibition titled Others 1, examined work created between 1960 and 1967, while Others 2, on view from May 25 ? August 3, presented work created between 1967 and 1970, some of which was directly influenced by the 1966 Primary Structures exhibition at the Jewish Museum." -- publisher''s statement.

Paperback. Zustand: new. Paperback. The NVIDIA Rubin CPX GPU Architecture: Transforming Inference Infrastructure for High-Performance Computing and Generative Applications The NVIDIA Rubin CPX GPU Architecture presents a comprehensive examination of the transformative advancements in artificial intelligence infrastructure, spotl…ighting NVIDIA's pioneering Rubin CPX GPU and the Vera Rubin NVL144 CPX platform. This book details the architectural ingenuity behind these innovations to address the escalating demands of million-token workloads in software development, generative video production, and autonomous AI agent systems. With a robust 30 petaflops of NVFP4 compute power and 128GB of cost-efficient GDDR7 memory, the Rubin CPX redefines efficiency in the compute-intensive prefill phase of AI inference, while the Vera Rubin NVL144 CPX platform delivers an impressive 8 exaflops of AI compute and 100TB of fast memory within a single rack, achieving a 7.5-fold performance leap over its predecessor, the GB300 NVL72. This book outlines the disaggregated inference model, which optimizes resource allocation by separating compute-bound and memory-bound phases, supported by NVIDIA's sophisticated Dynamo orchestration platform and advanced networking solutions such as Quantum-X800 InfiniBand and Spectrum-X Ethernet. Through compelling case studies, it showcases how industry leaders like Cursor, Runway, and Magic are leveraging these technologies to revolutionize software engineering, cinematic content creation, and AI-driven automation. The book also highlights the substantial economic advantages, with the potential to generate $5 billion in token revenue for every $100 million invested, making it a compelling proposition for enterprises seeking to capitalize on AI-driven opportunities. Further, the book examines the seamless integration of NVIDIA's AI stack, including the Nemotron family of multimodal models and CUDA-X libraries, which empower developers to deploy sophisticated applications with ease. It provides an analysis of the competitive landscape, assessing the impact of NVIDIA's innovations on rivals and outlining the future trajectory of specialized AI hardware. The NVIDIA Rubin CPX GPU Architecture is an essential resource for technologists, enterprise architects, and business strategists aiming to navigate the complexities of next-generation AI infrastructure. This volume equips readers with the knowledge to harness top-notch technologies, drive innovation, and achieve unparalleled returns in the rapidly evolving AI ecosystem. ORDER A COPY NOW!!!
