Techsolo TN-100 Gigabit Express Card Performance on Linux

This devices are detected on Linux and work out of the box, but are slow and get very hot. Maximum performance is just a little bit more than 500 Mbps which is very poor. My guess is that the poor performance is caused by the PCI and not PCIe chipset: VIA Velocity VT6122

So if you have a choice, keep away from these devices.

Creating 32 bits chroot on 64 bits system

I use Fedora 64 bits on my workstation but I need 32 bits chroot of Debian. It is easy to do. Create the chroot following the instructions from:  http://blog.parahard.com/2013/03/creating-debian-chroot-inside-fedora.html The first difference is that you need to add --arch=i386 to the debootstrap command. Then for entering the chroot add linux32 as the first argument after sudo. Something like: $ sudo linux32 chroot debian-wheezy After that even uname -a will show 32 bits instead of 64. The linux32 tool is on the util-linux Fedora package.

Fedora: Creating Debian chroot with ssh server

I use Fedora on the Desktop but I need to do some development on Debian. chroots gives you no performance overhead, while virtual machines gives you CPU and memory insulation. Also the chroot is only a directory on my development tree. I'm using Fedora 17 on my workstation and Debian 7 inside the chroot. The debootstrap command will save the files on the directory debian7-chroot/ under the current directory. 1 - Install debootstrap and dpkg on Fedora: Fedora # yum install debootstrap dpkg 2 - Create the basic Debian: Fedora # debootstrap wheezy debian7-chroot/ http://ftp.fr.debian.org/debian 3 - Enter your new Debian: Fedora # chroot /path/to/destdir 4 - Install additional useful packages: debian-chroot: # apt-get install locales less vim openssh-server sudo aptitude 5 - Configure openssh server to start server on port 2222: debian-chroot: # vi /etc/ssh/sshd_config Chage: Port 22 To: Port 2222 6 - Change root password debian-chroot: # p...

Rumo ao TOP500

Finalmente obtive o resultado da potência do cluster. O melhor número obtido foi 10,27 Gflops. O computador que esta na posição número 500 do TOP500 de 11/2004 marcou 850.6Gflops. O resultado é bom se o preço do cluster for levado em conta. O investimento foi inferior a R$ 20.000,00 ($ 8000,00). Veja a saida do HPLinpack aqui
