  • ROOT I/O Compression Improvements for HEP Analysis
    EPJ Web of Conferences 245, 02017 (2020) https://doi.org/10.1051/epjconf/202024502017 CHEP 2019 ROOT I/O compression improvements for HEP analysis Oksana Shadura1;∗ Brian Paul Bockelman2;∗∗ Philippe Canal3;∗∗∗ Danilo Piparo4;∗∗∗∗ and Zhe Zhang1;y 1University of Nebraska-Lincoln, 1400 R St, Lincoln, NE 68588, United States 2Morgridge Institute for Research, 330 N Orchard St, Madison, WI 53715, United States 3Fermilab, Kirk Road and Pine St, Batavia, IL 60510, United States 4CERN, Meyrin 1211, Geneve, Switzerland Abstract. We overview recent changes in the ROOT I/O system, enhancing it by improving its performance and interaction with other data analysis ecosys- tems. Both the newly introduced compression algorithms, the much faster bulk I/O data path, and a few additional techniques have the potential to significantly improve experiment’s software performance. The need for efficient lossless data compression has grown significantly as the amount of HEP data collected, transmitted, and stored has dramatically in- creased over the last couple of years. While compression reduces storage space and, potentially, I/O bandwidth usage, it should not be applied blindly, because there are significant trade-offs between the increased CPU cost for reading and writing files and the reduces storage space. 1 Introduction In the past years, Large Hadron Collider (LHC) experiments are managing about an exabyte of storage for analysis purposes, approximately half of which is stored on tape storages for archival purposes, and half is used for traditional disk storage. Meanwhile for High Lumi- nosity Large Hadron Collider (HL-LHC) storage requirements per year are expected to be increased by a factor of 10 [1].

  • Unix Command Line; Editors
    Unix command line; editors Karl Broman Biostatistics & Medical Informatics, UW–Madison kbroman.org github.com/kbroman @kwbroman Course web: kbroman.org/AdvData My goal in this lecture is to convince you that (a) command-line-based tools are the things to focus on, (b) you need to choose a powerful, universal text editor (you’ll use it a lot), (c) you want to be comfortable and skilled with each. For your work to be reproducible, it needs to be code-based; don’t touch that mouse! Windows vs. Mac OSX vs. Linux Remote vs. Not 2 The Windows operating system is not very programmer-friendly. Mac OSX isn’t either, but under the hood, it’s just unix. Don’t touch the mouse! Open a terminal window and start typing. I do most of my work directly on my desktop or laptop. You might prefer to work remotely on a server, instead. But I can’t stand having any lag in looking at graphics. If you use Windows... Consider Git Bash (or Cygwin) or turn on the Windows subsystem for linux 3 Cygwin is an effort to get Unix command-line tools in Windows. Git Bash combines git (for version control) and bash (the unix shell); it’s simpler to deal with than Cygwin. Linux is now accessible in Windows 10, but you have to enable it. If you use a Mac... Consider Homebrew and iTerm2 Also the XCode command line tools 4 Homebrew is a packaging system; iTerm2 is a Terminal replacement. The XCode command line tools are a must for most unixy things on a Mac.
