Implementing Compression on Distributed Time Series Database
Implementing compression on distributed time series database Michael Burman School of Science Thesis submitted for examination for the degree of Master of Science in Technology. Espoo 05.11.2017 Supervisor Prof. Kari Smolander Advisor Mgr. Jiri Kremser Aalto University, P.O. BOX 11000, 00076 AALTO www.aalto.fi Abstract of the master’s thesis Author Michael Burman Title Implementing compression on distributed time series database Degree programme Major Computer Science Code of major SCI3042 Supervisor Prof. Kari Smolander Advisor Mgr. Jiri Kremser Date 05.11.2017 Number of pages 70+4 Language English Abstract Rise of microservices and distributed applications in containerized deployments are putting increasing amount of burden to the monitoring systems. They push the storage requirements to provide suitable performance for large queries. In this paper we present the changes we made to our distributed time series database, Hawkular-Metrics, and how it stores data more effectively in the Cassandra. We show that using our methods provides significant space savings ranging from 50 to 95% reduction in storage usage, while reducing the query times by over 90% compared to the nominal approach when using Cassandra. We also provide our unique algorithm modified from Gorilla compression algorithm that we use in our solution, which provides almost three times the throughput in compression with equal compression ratio.

Intel® Quick Sync Video and Ffmpeg Installation and Validation Guide
White paper Intel® Quick Sync Video and FFmpeg Installation and Validation Guide Introduction Intel® Quick Sync Video technology on Intel® Iris™ Pro Graphics and Intel® HD graphics provides transcode acceleration on Linux* systems in FFmpeg* 2.8 and later editions. This paper is a detailed step-by-step guide to enabling h264_qsv, mpeg2_qsv, and hevc_qsv hardware accelerated codecs in the FFmpeg framework. For a quicker overview, please see this article. Performance note: The *_qsv implementations are intended to provide easy access to Intel hardware capabilities for FFmpeg users, but are less efficient than custom applications optimized for Intel® Media Server Studio. Document note: Monospace type = command line inputs/outputs. Pink = highlights to call special attention to important command line I/O details. Getting Started 1. Install Intel Media Server Studio for Linux. Download from software.intel.com/intel-media-server- studio. This is a prerequisite for the *_qsv codecs as it provides the foundation for encode acceleration. See the next chapter for more info on edition choices. Note: Professional edition install is required for hevc_qsv. 2. Get the latest FFmpeg source from https://www.FFmpeg.org/download.html. Intel Quick Sync Video support is available in FFmpeg 2.8 and later editions. The install steps outlined below were verified with ffmpeg release 3.2.2 3. Configure FFmpeg with “--enable –libmfx –enable-nonfree”, build, and install. This requires copying include files to /opt/intel/mediasdk/include/mfx and adding a libmfx.pc file. More details below. 4. Test transcode with an accelerated codec such as “-vcodec h264_qsv” on the FFmpeg command line. -
Concepts and Approaches for Mars Exploration1
June 24, 2012 Concepts and Approaches for Mars Exploration1 ‐ Report of a Workshop at LPI, June 12‐14, 2012 – Stephen Mackwell2 (LPI) Michael Amato (NASA Goddard), Bobby Braun (Georgia Institute of Technology), Steve Clifford (LPI), John Connolly (NASA Johnson), Marcello Coradini (ESA), Bethany Ehlmann (Caltech), Vicky Hamilton (SwRI), John Karcz (NASA Ames), Chris McKay (NASA Ames), Michael Meyer (NASA HQ), Brian Mulac (NASA Marshall), Doug Stetson (SSECG), Dale Thomas (NASA Marshall), and Jorge Vago (ESA) Executive Summary Recent deep cuts in the budget for Mars exploration at NASA necessitate a reconsideration of the Mars robotic exploration program within NASA’s Science Mission Directorate (SMD), especially in light of overlapping requirements with future planning for human missions to the Mars environment. As part of that reconsideration, a workshop on “Concepts and Approaches for Mars Exploration” was held at the USRA Lunar and Planetary Institute in Houston, TX, on June 12‐14, 2012. Details of the meeting, including abstracts, video recordings of all sessions, and plenary presentations, can be found at http://www.lpi.usra.edu/meetings/marsconcepts2012/. Participation in the workshop included scientists, engineers, and graduate students from academia, NASA Centers, Federal Laboratories, industry, and international partner organizations. Attendance was limited to 185 participants in order to facilitate open discussion of the critical issues for Mars exploration in the coming decades. As 390 abstracts were submitted by individuals interested in participating in the workshop, the Workshop Planning Team carefully selected a subset of the abstracts for presentation based on their appropriateness to the workshop goals, and ensuring that a broad diverse suite of concepts and ideas was presented. -

Scripting the OpenSSH, SFTP, and SCP Utilities on i Presented by Scott Klement http://www.scottklement.com © 2010-2015, Scott Klement Why do programmers get Halloween and Christmas mixed-up? 31 OCT = 25 DEC Objectives Of This Session • Setting up OpenSSH on i • The OpenSSH tools: SSH, SFTP and SCP • How do you use them? • How do you automate them so they can be run from native programs (CL programs) 2 What is SSH SSH is short for "Secure Shell." Created by: • Tatu Ylönen (SSH Communications Corp) • Björn Grönvall (OSSH – short lived) • OpenBSD team (led by Theo de Raadt) The term "SSH" can refer to a secured network protocol. It also can refer to the tools that run over that protocol. • Secure replacement for "telnet" • Secure replacement for "rcp" (copying files over a network) • Secure replacement for "ftp" • Secure replacement for "rexec" (RUNRMTCMD) 3 What is OpenSSH OpenSSH is an open source (free) implementation of SSH. • Developed by the OpenBSD team • but it's available for all major OSes • Included with many operating systems • BSD, Linux, AIX, HP-UX, MacOS X, Novell NetWare, Solaris, Irix… and yes, IBM i. • Integrated into appliances (routers, switches, etc) • HP, Nokia, Cisco, Digi, Dell, Juniper Networks "Puffy" – OpenBSD's Mascot The #1 SSH implementation in the world. • More than 85% of all SSH installations. • Measured by ScanSSH software. • You can be sure your business partners who use SSH will support OpenSSH 4 Included with IBM i These must be installed (all are free and shipped with IBM i **) • 57xx-SS1, option 33 = PASE • 5733-SC1, *BASE = Portable Utilities • 5733-SC1, option 1 = OpenSSH, OpenSSL, zlib • 57xx-SS1, option 30 = QShell (useful, not required) ** in v5r3, had 5733-SC1 had to be ordered separately (no charge.)
