RHEL 6.2 – Ganglia’s gmond Python module for monitoring NVIDIA GPU

Disclaimer

The instructions/steps given below worked for me (and Michigan Technological University) running site licensed Red Hat Enterprise Linux 6.2 – as has been a common practice for several years now, a full version of Operating System was installed and all necessary patches/upgrades have been applied. These instructions may very well work for you (or your institution), on Red Hat-like or other linux distributions. Please note that if you decide to use these instructions on your machine, you are doing so entirely at your very own discretion and that neither this site, sgowtham.com, nor its author (or Michigan Technological University) is responsible for any/all damage – intellectual and/or otherwise.

BASH – Extracting Subversion Log

Subversion

Subversion Subversion (SVN) is a version control system initiated in 2000 by CollabNet Inc. It is used to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly-compatible successor to the widely used Concurrent Versions System (CVS). Subversion is well-known in the open source community and is used on many open source projects.

Subversion was started in 2000 as an effort to write a free version control system which operated much like CVS but with fixed bugs and misfeatures in CVS. By 2001, Subversion was sufficiently developed to be capable of hosting its own source code. More information, including this above paragraphs, is here.

BASH – Wrappers For qstat In NPACI ROCKS 5.2.2

What is ROCKS?

Rocks Cluster Distribution (originally called NPACI Rocks) is a Linux distribution intended for high-performance computing clusters. It was started by NPACI and the SDSC in 2000, and was initially funded in part by an NSF grant (2000-2007) but is currently funded by the followup NSF grant. Rocks was initially based on the Red Hat Linux distribution, however modern versions of Rocks are now based on CentOS, with a modified Anaconda installer that simplifies mass installation onto many computers. Rocks includes many tools (such as MPI) which are not part of CentOS but are integral components that make a group of computers into a cluster. Installations can be customized with additional software packages at install-time by using special user-supplied CDs (called Roll CDs). The Rolls extend the system by integrating seamlessly and automatically into the management and packaging mechanisms used by base software, greatly simplifying installation and configuration of large numbers of computers. Over a dozen Rolls have been created, including the SGE roll, the Condor roll, the Lustre roll, the Java roll, and the ganglia roll.

PHP – Displaying Gravatars In A Non-WordPress Application

Citing their website, an Automattic.com joint:,

A gravatar, or globally recognized avatar, is quite simply an avatar image that follows you from weblog to weblog appearing beside your name when you comment on gravatar enabled sites. Avatars help identify your posts on web forums, so why not on weblogs?

It’s free and with one account, one can register and assign multiple email address the same (or different) avatar(s).

BASH – GZIP or BZIP2?

BASH is a free software Unix shell written for the GNU Project. Its name is an acronym which stands for Bourne-again shell. The name is a pun on the name of the Bourne shell (sh), an early and important UNIX shell written by Stephen Bourne and distributed with Version 7 Unix circa 1978, and the concept of being born again. BASH was created in 1987 by Brian Fox. In 1990 Chet Ramey became the primary maintainer. BASH is the default shell on most GNU/Linux systems as well as on Mac OS X and it can be run on most UNIX-like operating systems. It has also been ported to Microsoft Windows using the POSIX emulation provided by Cygwin, to MS-DOS by the DJGPP project and to Novell NetWare.

Expect – Remote SSH Login

Expect is a UNIX automation and testing tool, written by Don Libes as an extension to the Tcl scripting language, for interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip, ssh, and others. It uses UNIX pseudo terminals to wrap up sub-processes transparently, allowing the automation of arbitrary applications that are accessed over a terminal. With Tk, interactive applications can be wrapped in X11 GUIs. Expect has regular expression pattern matching and general program capabilities, allowing simple scripts to intelligently control programs such as telnet, ftp, and ssh, all of which lack a programming language, macros, or any other program mechanism. The result is that Expect scripts provide old tools with significant new power and flexibility.
