In this video from the 2015 OFS Developer’s Workshop, Parav Pandit from Emulex presents: Workload Driven Memory Registration.
“IBM Spectrum Scale is a proven, scalable, high-performance data and file management solution (based upon IBM General Parallel File System or GPFS, also formerly known as code name Elastic Storage). IBM Spectrum Scale provides world-class storage management with extreme scalability, flash accelerated performance, and automatic policy-based storage tiering from flash through disk to tape. IBM Spectrum Scale reduces storage costs up to 90% while improving security and management efficiency in cloud, big data & analytics environments.”
“To achieve good scalability performance on the HPC scientific applications typically involves good understanding of the workload though performing profile analysis, and comparing behaviors of using different hardware which pinpoint bottlenecks in different areas of the HPC cluster. In this session, a selection of HPC applications will be shown to demonstrate various methods of profiling and analysis to determine the bottleneck, and the effectiveness of the tuning to improve on the application performance.”
The Open Compute Project partners with leading CPU vendors such as Intel, AMD and ARM-based vendors to create reference designs that may be used by board and system vendors. These designs are bare-bones systems, with expansion options designed in for other types of I/O and storage. The reference design from Intel (REF) is 6.5 inches wide and 20 inches deep. These dimensions allow for three servers to be placed side by side in a newly designed Open Compute rack, increasing density.
“Computers used as datacenter servers have usage patterns that differ substantially from those of desktop or laptop computers. We discuss four key differences in usage and their first-order implications for designing computers that are particularly well-suited as servers: data movement, thousands of transactions per second, program isolation, and measurement underpinnings. Maintaining high-bandwidth data movement requires coordinated design decisions throughout the memory system, instruction-issue system, and even instruction set.”
In this video from the 2015 HPC Advisory Council Switzerland Conference, Branislav Jansík from the Technical University of Ostrava presents: IT4Innovations National Supercomputing Center. “Our mission is to deliver scientifically excellent and industry relevant research in the fields of high performance computing and embedded systems.”
