“MeteoSwiss, the Swiss national weather forecast institute, has selected densely populated accelerator servers as their primary system to compute weather forecast simulation. Servers with multiple accelerator devices that are primarily connected by a PCI-Express (PCIe) network achieve a significantly higher energy efficiency. Memory transfers between accelerators in such a system are subjected to PCIe arbitration policies. In this paper, we study the impact of PCIe topology and develop a congestion-aware performance model for PCIe communication. We present an algorithm for computing congestion factors of every communication in a congestion graph that characterizes the dynamic usage of network resources by an application.”
Today One Stop Systems (OSS) introduced a pair of high-speed networked storage appliances that supports high-performance, shared storage services. “The OSS approach optimizes the hardware for the environment and optimizes the software for the application in the Flash Storage Array for Networks product line (FSAn). This hardware and software optimization in the FSAn product line provides the best ROI in any environment by minimizing hardware and license costs through advance array-level optimizations while maximizing the utilization of the flash array through VSI and VDI application support.”
“High performance systems now typically a host processor and a coprocessor. The role of the coprocessor is to provide the developer and the user the ability to significantly speed up simulations if the algorithm that is used can run with a high degree of parallelization and can take advantage of an SIMD architecture. The Intel Xeon Phi coprocessor is an example of a coprocessor that is used in many HPC systems today.”
“We’ve seen the rapid evolution of SSDs and have been contributing to the NVMe over Fabrics standard and community drivers,” said Michael Kagan, CTO at Mellanox Technologies. “Because faster storage requires faster networks, we designed the highest-speeds and most intelligent offloads into both our ConnectX-5 and BlueField families. This lets us connect many SSDs directly to the network at full speed, without the need to dedicate many CPU cores to managing data movement, and we provide a complete end-to-end networking solution with the highest-performing 25, 50, and 100GbE switches and cables as well.”
Today One Stop Systems introduced the Magma StorageBox 1000 PCIe expansion system. Targeted for HPC applications, the SBB1000 provides up to 25.6TB of NVMe SSD direct attached storage through eight 2.5″ drives to any standard server.
“We have partnered with Liqid to provide our customers with a leading option for enterprise-class flash storage. OSS is one of the only companies currently producing expansion products as dense as this FSA. By combining our PCIe expertise with Liqid’s PCIe flash storage and software expertise, we have created a state-of-the-art flash array that can provide fast response time, high-availability, and high-speed data processing in data centers, cloud environments, mega websites, and high-performance applications.”
Today Mellanox announced the BlueField family of programmable processors for networking and storage applications. “As a networking offload co-processor, BlueField will complement the host processor by performing wire-speed packet processing in-line with the network I/O, freeing the host processor to deliver more virtual networking functions (VNFs),” said Linley Gwennap, principal analyst at the Linley Group. “Network offload results in better rack density, lower overall power consumption, and deterministic networking performance.”
Today One Stop Systems announced the results of High-Tech Online Magazine Tom’s IT PRO’s review of the 200TB Flash Storage Array SAN (FSA-SAN). OSS’ FSA-SAN provides 200TB of shared Flash RAIDed memory with a choice of the fastest SAN connectivity options including Fiber Channel, Infiniband, and iSCSI.
