Philippine Weather Service Finds Forecasting Cheaper with Debian Linux Cluster

Posted on in Categories Debian Linux, GNU/Open source, Hardware, High performance computing, Linux, Save money with FOSS last updated March 14, 2008

Yet another Linux success story; From the article:

The Philippine government’s official weather service, PAGASA, has replaced its SGI supercomputer with a clustered Debian Linux system that can process information vital to protection against typhoons, floods, droughts, tsunamis and other wild weather conditions at a fraction of the cost.

The cluster includes eight PCs running as a single node, connected via a gigabit switch, each with dual 64-bit Intel Xeon processors running the Debian Linux OS.

SAP To Roll Out ERP Linux Server Appliance

Posted on in Categories Hardware, Howto, Linux, Linux distribution, Make money with Linux, News, Suse Linux last updated March 5, 2008

SAP and Intel , the world’s biggest makers of business software and microchips, will jointly offer servers pre-packaged with SAP software aimed at medium-sized firms, the two companies said.

SAP aims to provide customers with a 45% savings on implementation and a 25% savings on total cost of ownership over what they’d typically spend for a comparable hardware/software combo, said Jans Peter Klaey, president of global SME at SAP, in an interview.

The server is available in five Northern European countries and should reach 20 countries this year.

Find and Fix Linux Latency Problem with LatencyTOP Software

Posted on in Categories GNU/Open source, Howto, Linux, Linux desktop, Monitoring, Troubleshooting, Tuning last updated January 19, 2008

A TOP-like tool for monitoring system latency and its causes for Linux system.

The Intel Open Source Technology Center is pleased to announce the release of version 0.1 of LatencyTOP, a tool for developers to visualize system latencies. Skipping audio, slower servers, everyone knows the symptoms of latency. But to know what’s going on in the system, what’s causing the latency, how to fix it… that’s a hard question without good answers right now.

LatencyTOP is a Linux tool for software developers (both kernel and userspace), aimed at identifying where in the system latency is happening, and what kind of operation/action is causing the latency to happen so that the code can be changed to avoid the worst latency hiccups.

How to: Upgrade Fedora Linux From 32-bit System to 64-bit Version w/o Reinstalling Server

Posted on in Categories Howto, Links, Linux, RedHat/Fedora Linux, Tips last updated January 13, 2008

This small guide may come handy…

From the article:

One great thing about Linux is that you can transplant a hard disk from a machine that runs a 32-bit AMD XP processor into a new 64-bit Intel Core 2 machine, and the Linux installation will continue to work. However, if you do this, you’ll be running a 32-bit kernel, a C library, and a complete system install on a processor that could happily run 64-bit code. You’ll waste even more resources if your new machine has 4GB or more of system memory, and you’ll be forced to either not use some of it or run a 32-bit Physical Address Extension (PAE) kernel. Cross-grading to the 64-bit variant of your Linux distribution can help you use your resources more wisely. A disclaimer: changing the architecture of your Fedora installation from 32 to 64-bit isn’t recommended or supported in any way. Perform this at your own risk after creating a suitable backup.

Download of the day: PowerTOP ~ Save and Extend Linux Laptop Battery

Posted on in Categories Download of the day, Hardware, Howto, Links, Linux, Linux desktop, Linux distribution, Linux laptop last updated January 10, 2008

Powertop is Linux tool to find out what is using power on a laptop. This program only works on Intel based laptops. It is very good software to extend Laptop battery life time. I’ve tested this software with following Intel based laptops:
=> My Sony VAIO Laptop
=> My Dell 6400 Laptop
=> My office HP / Compaq Laptop

From the project page:

Computer programs can make your computer use more power. PowerTOP is a Linux tool that helps you find those programs that are misbehaving while your computer is idle.

PowerTOP combines various sources of information from the kernel into one convenient screen so that you can see how well your system is doing at saving power, and which components are the biggest problems.

PowerTOP has these four basic goals:

=> Show how well your system is using the various hardware power-saving features
=> Show you the culprit software components that are preventing optimal usage of your hardware power savings
=> Help Linux developers test their application and achieve optimal behavior
=> Provide you with tuning suggestions to achieve low power consumption

Quick PowerTOP installation

Type the following commands:
$ sudo apt-get install powertop
$ sudo powetop

Get Free Interactive Shell Access to Linux / BSD and UNIX Like Operating Systems

Posted on in Categories Links, Linux, Shell scripting, UNIX last updated January 1, 2008

From my mail bag:

Where can I get free interactive access to HP-UX or Linux distro or UNIX shell access?

You can simply grab and try out any Linux / BSD / Solaris Live CD. However, some time you cannot install and use particular UNIX like os. So, if you want to try the latest technologies over the Internet? Try HP TestDrive program:

This program allows you to testdrive some of the hottest hardware and operating systems available today. Have you ever wanted to try out HP’s exciting 64-bit Integrity and PA-RISC technology? Get time on SMP x86 and Opteron ProLiant servers? Try out a Blade server. Try different Open Source operating systems such as FreeBSD, Suse, Redhat, Debian and other Linux distributions.

This program is perfect for students and new users to try out and learn basis of UNIX. You can also try and test your C/C++ programs using latest Intel compilers. It is intended for those users who want to sample the 32- and 64-bit servers running a variety of HP, UNIX, Linux and third-party operating systems and applications.

Linux Fibre Channel over Ethernet implementation code released

Posted on in Categories Linux, Linux Scalability, Linux Virtualization, Networking, Open source coding, Storage last updated December 18, 2007

Intel has just released source code for Fibre Channel over Ethernet (FCoE). It provides some Fibre Channel protocol processing as well as the encapsulation of FC frames within Ethernet packets. FCoE will allow systems with an Ethernet adapter and a Fibre Channel Forwarder to login to a Fibre Channel fabric (the FCF is a “gateway” that bridges the LAN and the SAN). That fabric login was previously reserved exclusively for Fibre Channel HBAs. This technology reduces complexity in the data center by aiding network convergence. It is targeted for 10Gps Ethernet NICs but will work on any Ethernet NIC supporting pause frames. Intel will provide a Fibre Channel protocol processing module as well as an Ethernet based transport module. The Open-FC module acts as a LLD for SCSI and the Open-FCoE transport uses net_device to send and receive packets.

This is good news. I think one can compare bandwidth and throughput for copper and fiber Ethernet. If you are going to use copper you need to stay within 15m of the switch. This solution will try to bring down cost. One can connect to 8-10 server to central database server with 10G and there could be few more applications.
