Newer enterprise-class hardware is starting to use UEFI instead of BIOS. UEFI is a big improvement, but there isn’t much documentation on the subject. Today I had to configure the UEFI for a new node in our cluster. I wanted to configure it exactly like an existing node that works. It was challenging just to […]

I recently installed ATLAS on my new workstation and I’ve been wondering what kind of performance gain I would get compared to the reference BLAS. After some searching, I finally found a BLAS benchmarking tool called BLASbench, which is part of the LLCbench suite. This tool has a rather strange build process, so follow the

In a previous post I described how to build an optimized version of NumPy using the Intel compilers and Math Kernel Library (MKL). This post will update those instructions, since it has been a few years and I am now using NumPy 1.6.1, MKL 10.0.1.014 and Red Hat 4.1.1 (kernel 2.6.18-8.el5). First, copy the file

Prerequisites: boost-devel, openmpi-devel, valgrind-devel I installed PETSc and libMesh in my user directory, since I have a single-user workstation. Installing PETSc for use with libMesh First, ensure that OpenMPI is installed and the system paths have been configured correctly. You will need to add the directory containing OpenMPI binaries to your $PATH, and the directory

I finally got around to installing Paraview on my CentOS 5 box. There are no official RPMS for CentOS 5, so I was expecting a painful build process. To my great surprise, I was able to download the Paraview binary for Linux (64-bit) from Kitware, unpack the archive, and run it! As root, I placed

I recently upgraded my desktop workstation from an old 32-bit version of Gentoo to 64-bit CentOS 5. I downloaded and installed the latest version of Sage, and the process went smoothly. If you find this post helpful, please check out the Sage Beginner’s Guide at Packt Publishing. Since I don’t use Sage every day, I

The following kernel configuration was posted by Alessandro Di Marco as a comment on a previous post in which I provided a Linux kernel config for an earlier version of the kernel. In the interest of sharing his contribution, I’m placing it in its own post. I don’t know the author personally and I have

EDIT: added –enable-shared to configure script for building Python, and added /home/yourname/lib to shared library path. This is necessary for building some packages such as pycairo (which you may need to build pygtk and matplotlib). EDIT 2: you should use the –prefix=/home/yourusername instead of –user. The prefix option places packages in the standard location: /home/yourusername/lib/python2.7/site-packages.

sed is a stream editor, which means that it accepts a stream of text, processes it, and spits out another stream of text. sed can process files that are too large to load into memory, and it is a completely command-line tool that can easily be integrated into shell scripts. This excellent sed tutorial was

I’m using GNU Fortran (gfortran) to build several shared libraries, and then dynamically linking to them from a Fortran program. The process is a little different than what I’m used to for C libraries, so I thought I’d explain it. Unlike C, there is no need to #include header files when compiling code that relies
