Space-Time Processing—Linux Style
Linux Tools for VHDL
Simulation tools let you write VHDL, simulate and debug it, but you need a synthesis tool if you want to run your VHDL in hardware. Many simulation tools have graphical waveform displays. Most professional VHDL tools will run on Linux. Free tools include FreeHDL and GHDL, a GCC front end for VHDL.
Synthesis takes working VHDL and maps it to a hardware device, such as an FPGA or MPGA (mask programmed gate array). This is device-specific, so free tools are rare. Big manufacturers support Linux with proprietary tools. Altera Quartus is available for Linux but not in the Web edition. Xilinx ISE also is available for Linux but not in the Web pack edition. Pages on-line can tell you how to get Quartus and ISE running on Linux (see Resources).

Ian McLoughlin has used Linux for about 12 years and has a signal processing background. Before emigrating to New Zealand, he was a university lecturer in Singapore and still travels there frequently as a Visiting Scientist to the XSat Satellite Programme (due for launch in 2006). He is married with two young Linux-using kids.
Tom Scott is a director of Mission Technologies Ltd., (www.missiontech.co.nz) known for his terse, straightforward, no-nonsense, hands-on approach. Father of two, husband of one and a wanna-be missionary.
Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
