Implementation of a Linux Kernel Module to Stress Test Memory Subsystems in X86 Architecture
Robert Taylor Implementation of a Linux Kernel Module to Stress Test Memory Subsystems in x86 Architecture Helsinki Metropolia University of Applied Sciences Bachelor of Engineering Information Technology 27th February 2011 Abstract Author(s) Robert Taylor Title Implementation of a Linux Kernel Module to Stress Test Memory Subsystems in x86 Architecture Number of Pages 36 pages Date 27 February 2011 Degree Bachelor of Engineering Degree Programme Information Technology Specialisation option Software Engineering Antti Piironen, Dr (Project Supervisor) Instructors Janne Kilpelainen (Hardware Supervisor, NSN) Antti Virtaniemi (Software Supervisor, NSN) The aim of the project was to implement software which would stress test the memory subsystem of x86 based hardware for Nokia Siemens Networks (NSN). The software was to be used in the validation process of memory components during hardware develop- ment. NSN used a number of software tools during this process. However, none met all their requirements and a custom piece of software was required. NSN produced a detailed requirements specification which formed the basis of the project. The requirements left the implementation method open to the developer. After analysing the requirements document, a feasibility study was undertaken to determine the most fitting method of implementation. The feasibility study involved detailed discussions with senior engineers and architects within both the hardware and software fields at NSN. The study concluded that a Linux kernel module met the criteria best. The software was successfully implemented as a kernel module and met the majority of the requirements set by NSN. The software is currently in use at NSN and is being actively updated and maintained. -

Intel CEO Remarks Q1'21 Earnings Webcast April 22, 2021
Intel CEO Remarks Q1’21 Earnings Webcast April 22, 2021 Pat Gelsinger, Intel CEO Good afternoon everyone. It’s a pleasure to be with you for my first earnings call. I consider it an honor to be CEO of this great company. Thanks for joining. Intel delivered a strong Q1 that beat our January guide on both the top and bottom line, driven by exceptional demand for our products and exquisite execution by our team. We shipped a record volume of notebook CPUs. We launched new competitive Intel® Core™ and Xeon® processors. Mobileye had its best quarter ever. With tremendous industry support, we unveiled our IDM 2.0 strategy, setting a bold new course for technology leadership at Intel. The response from employees, partners and customers has been incredible. Our teams are re- invigorated, innovating and executing. It’s amazing to be back at Intel ... and Intel is back. Before George takes you through the financial details of the quarter, I’ll begin with the industry trends we’re seeing and why Intel is well positioned to aggressively capitalize on them. Said simply, Intel is the only company with the depth and breadth of software, silicon and platforms, and packaging and process with at-scale manufacturing that customers can depend on for their next-generation innovations. There are four superpowers driving digital transformation: cloud, connectivity, artificial intelligence and the intelligent edge. Intel’s mission, and we are uniquely positioned to do so, is to help customers harness these superpowers to improve the lives of every human on the planet The digitization of everything was markedly accelerated by COVID and has spurred innovation and new models of working, learning, interacting and caring. -
