Impact of Meltdown and Spectre Vulnerabilities on HPC

“Performance is important in high performance computing. A performance impact on HPC use can be more than a simple annoyance. Because of the high investment cost and energy usage of HPC systems, a performance impact can have a signi cant effect on price per compute job. As we have discussed in the previous sections, the “page table isolation” workarounds have an overhead on entering and leaving the kernel. Luck happens that in HPC, computers spend most of their time in user space, doing computations. Low-latency networks such as In niband allow HPC systems to perform network communication without involving the kernel. Therefore during HPC computations, the Linux kernel might not be actively involved and the CPUs are running at full power.”

Energy Efficiency in the Software Stack — Cross Community Efforts

This report covers events at SC17 that focused on energy efficiency and highlights ongoing collaborations across the community to develop advanced software technologies for system energy and power management.

HPC Moves to the Cloud – What You Need to Know

While some domains that rely on computing systems are satisfied with the performance gains that are continuously delivered from processor manufacturers, others require performance that can only be attained through massive parallelism. High-performance computing is for those that need the highest performance in order to solve many of today’s most difficult scientific challenges.

How to Leverage HPC in the Enterprise

Despite the proven benefits of HPC in the enterprise, many businesses still struggle to overcome the complexity of deploying HPC solutions in their enterprise. To read several successful case studies and learn more about how to leverage HPC in your enterprise, download this white paper.

insideHPC Special Report: A Trusted Approach for High Performance Networking

The high performance networking interconnect landscape is in transition. InfiniBand and Intel Omni-Path will compete for the performance crown, while Ethernet will remain the ubiquitous standard for commercially oriented systems.

Parallel File System Delivers Better Strategies, Faster

A parallel file system offers several advantages over a single direct attached file system. By using fast, scalable, external disk systems with massively parallel access to data, researchers can perform analysis against much larger datasets than they can by batching large datasets through memory.

insideHPC Research Report on In-Memory Computing

To achieve high performance, modern computer systems rely on two basic methodologies to scale resources. A scale-up design that allows multiple cores to share a large global pool of memory and a scale-out design design that distributes data sets across the memory on separate host systems in a computing cluster. To learn more about In-Memory computing download this guide from IHPC and SGI.

Five Essential Strategies for Successful HPC Cluster

A successful HPC cluster is a powerful asset for an organization. At the same time, these powerful racks present a multifaceted resource to manage. If not properly managed, software complexity, cluster growth, scalability, and system heterogeneity can introduce project delays and reduce the overall productivity of an organization. At the same time, cloud computing models as well as the processing of Hadoop workloads are emerging challenges that can stifle business agility if not properly implemented. The following essential strategies are guidelines for the effective operation of an HPC cluster resource. Download this IHPC guide to learn more.
