Linux on POWER
http://ibmsystemsmag.com/CMSTemplates/IBMSystemsMag/Print.aspx?... close window Print May 2016 | by Jaqui Lynch IBM is serious about Linux on POWER. Linux now runs on every POWER8 server, with specialized offerings for Linux. These include the new LC (Linux only, PowerKVM only) servers, the L model (Linux only) servers, Linux IFLs, EasyScale for MSP offerings, and SAP Hana on POWER. Additionally, significant work has been done to encourage ISVs to increase their offerings on Linux on POWER, resulting in a flourishing ecosystem that wasn’t available on POWER five years ago. Power systems are designed for big data and optimized for performance and scalability. They provide great I/O and memory bandwidth with significant reliability and other availability features not available anywhere else except the mainframe. With full support for various levels of RHEL (Redhat Enterprise Linux), SLES (SuSE Linux Enterprise Server) and Ubuntu, it’s a great time to consider migrating to Linux on Power. Here are some decisions to make: 1. Do you want to run Linux alongside other workloads like AIX or IBM i 2. Do you want to run a Linux only server 3. Do you want to use and HMC or virtual HMC to control the server (won’t work with PowerKVM) 4. Do you want to use PowerKVM or PowerVM for virtualization 5. Do you have some dark cores and memory that you would like to run Linux on at a reduced rate 6. Do you have x86 workload running on Linux that you would like to migrate 7. Do you want to reduce costs for IBM software (PVU based licensing) Reducing costs Software can be expensive, especially middleware. -

Literature Review and Implementation Overview: High Performance
LITERATURE REVIEW AND IMPLEMENTATION OVERVIEW: HIGH PERFORMANCE COMPUTING WITH GRAPHICS PROCESSING UNITS FOR CLASSROOM AND RESEARCH USE APREPRINT Nathan George Department of Data Sciences Regis University Denver, CO 80221 [email protected] May 18, 2020 ABSTRACT In this report, I discuss the history and current state of GPU HPC systems. Although high-power GPUs have only existed a short time, they have found rapid adoption in deep learning applications. I also discuss an implementation of a commodity-hardware NVIDIA GPU HPC cluster for deep learning research and academic teaching use. Keywords GPU · Neural Networks · Deep Learning · HPC 1 Introduction, Background, and GPU HPC History High performance computing (HPC) is typically characterized by large amounts of memory and processing power. HPC, sometimes also called supercomputing, has been around since the 1960s with the introduction of the CDC STAR-100, and continues to push the limits of computing power and capabilities for large-scale problems [1, 2]. However, use of graphics processing unit (GPU) in HPC supercomputers has only started in the mid to late 2000s [3, 4]. Although graphics processing chips have been around since the 1970s, GPUs were not widely used for computations until the 2000s. During the early 2000s, GPU clusters began to appear for HPC applications. Most of these clusters were designed to run large calculations requiring vast computing power, and many clusters are still designed for that purpose [5]. GPUs have been increasingly used for computations due to their commodification, following Moore’s Law (demonstrated arXiv:2005.07598v1 [cs.DC] 13 May 2020 in Figure 1), and usage in specific applications like neural networks. -
