Reading Sections 5.1-5.5, in K&R GDB Reference Card (linked to class page under “resources.”) Optional: Complete GDB documentation (http://www.gnu.org/manual/gdb-5.1.1/gdb.html) Note: GDB currently only works on the following machines: • torus.cs.berkeley.edu • rhombus.cs.berkeley.edu • pentagon.cs.berkeley.edu Please ssh into one of these machines before starting the lab. Basic tasks in GDB There are two ways to start the debugger: 1. In EMACS, type M-x gdb, then type gdb <filename> 2. Run gdb <filename> from the command line The following are fundamental operations in gdb. Please make sure you know the gdb commands for the following operations before you proceed. 1. How do you run a program in gdb? 2. How do you pass arguments to a program when using gdb? 3. How do you set a breakpoint in a program? 4. How do you set a breakpoint which which only occurs when a set of conditions is true (eg when certain variables are a certain value)? 5. How do you execute the next line of C code in the program after a break? 1 6. If the next line is a function call, you'll execute the call in one step. How do you execute the C code, line by line, inside the function call? 7.

  • 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].

  • The GNOME Desktop Environment
    The GNOME desktop environment Miguel de Icaza ([email protected]) Instituto de Ciencias Nucleares, UNAM Elliot Lee ([email protected]) Federico Mena ([email protected]) Instituto de Ciencias Nucleares, UNAM Tom Tromey ([email protected]) April 27, 1998 Abstract We present an overview of the free GNU Network Object Model Environment (GNOME). GNOME is a suite of X11 GUI applications that provides joy to users and hackers alike. It has been designed for extensibility and automation by using CORBA and scripting languages throughout the code. GNOME is licensed under the terms of the GNU GPL and the GNU LGPL and has been developed on the Internet by a loosely-coupled team of programmers. 1 Motivation Free operating systems1 are excellent at providing server-class services, and so are often the ideal choice for a server machine. However, the lack of a consistent user interface and of consumer-targeted applications has prevented free operating systems from reaching the vast majority of users — the desktop users. As such, the benefits of free software have only been enjoyed by the technically savvy computer user community. Most users are still locked into proprietary solutions for their desktop environments. By using GNOME, free operating systems will have a complete, user-friendly desktop which will provide users with powerful and easy-to-use graphical applications. Many people have suggested that the cause for the lack of free user-oriented appli- cations is that these do not provide enough excitement to hackers, as opposed to system- level programming. Since most of the GNOME code had to be written by hackers, we kept them happy: the magic recipe here is to design GNOME around an adrenaline response by trying to use exciting models and ideas in the applications.
