Since Python is widely used as a high-productivity language for scientific computing, Intel has created a page showing how to build NumPy with Intel compilers and the Math Kernel Library (MKL). I would like to clarify a few items regarding building NumPy on a 64-bit Red Hat Enterprise Linux 5.4 system. Since this is a […]

This post will take you through the installation and configuration of an Infiniband card on a server running Red Hat Enterprise Linux 5.4. These steps are applicable to any version of Red Hat 5, and will probably work with version 6 as well. It has been surprisingly hard to find all of these steps in

Glossary of Infiniband Terminology: GID: Global Identifier GUID: Global Unique Identifiers (also known as Direct Address) HCA: Host Channel Adapter LID: Local Identifier TCA: Target Channel Adapter SM: Subnet Manager Infiniband: The Host Perspective Every host on an Infiniband fabric has three identifiers: GUID, GID, and LID. A GUID is similar in concept to a

xCAT is the eXtreme Cloud Administration Toolkit from IBM. It’s a suite of tools that IBM has developed to manage large groups of servers, such as a cloud infrastructure or a high-performance computing cluster (HPCC). I have only used xCAT to administer a mid-sized compute cluster (about 140 compute nodes totaling about 1400 cores running

Updated 2017-08-01 to fix typo and use new demo URL. Also note that the Homebrew package manager has matured since this post was first published in 2012. Once you’ve configured Homebrew, installing a tool like wget is as simple as running brew install wget wget is an incredibly useful GNU tool on Linux. Unfortunately, it

OpenFOAM is a notoriously difficult piece of software to compile, install and run. OpenCFD (the authors of OpenFOAM) have chosen to require the use of recent versions of gcc that are not available on most stable enterprise-class systems (ie Red Hat Enterprise Linux). To make things worse, until recently, OpenCFD also bundled a large number

The Problem I ran into what was probably the strangest error I have ever encountered as a Linux admin. I created a fresh CentoOS 6 virtual machine (VM) using VirtualBox on my OS X Mountain Lion system. To my great surprise, I was only able to access Google and a handful of other web sites

CFD-ACE+ is a multiphysics and computational fluid dynamics (CFD) simulation tool that was originally developed by CFD Research Corp. and is now distributed by ESI Software. The only platforms officially supported by CFD-ACE+ are Red Hat Enterprise Linux, SUSE Linux and Windows. Fortunately, it seems that ACE+ runs on other Linux distributions with only a

This is a follow-up to my earlier post about building NumPy with Intel compilers and the Intel MKL on CentOS 5. I will now explain how to build SciPy (which requires NumPy). First, download and unpack the SciPy source tarball. The following command can be used to build SciPy: LDFLAGS=”” FFLAGS=”-fPIC -openmp” python2.7 setup.py build
