The datasheet of Toshiba R830-10P mentions that the maximum memory capacity is 8GB. See it here . But Intel says that the i7-2620M supports up to 16GB of RAM. See it here . I have asked for help on Toshiba Forums. Nothing useful from there. See it here . I was curious as I have a very particular need for 16GB of RAM. Today I decided to give it a try. I bought two Patriot PSD38G13332S (8GB PC3 - 10600 1333MHz CL9 SoDimm) and installed it on the notebook. It just worked. So if you have the need for 16GB of RAM and a similar notebook from Toshiba, you can install 16GB of RAM.
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).

Pre-Notes: - This will work only if your Linux Distro is based on RPM and YUM. I have tested it on Fedora but it may also work on RHEL and Centos... It will NOT work on Ubuntu, Debian, Suse... - The operating system and its version will be the same inside and outside the chroot jail. - On the example, the chroot will be placed at: /chroot/devel - To install different version of Fedora or other RPM based distro, it will be necessary to manage yum package repositories outside the jail. The five steps: # 1 - Create the chroot directory $ sudo mkdir -p /chroot/devel/var/lib/rpm # 2 - Initiate rpm db on chroot $ sudo rpm --root /chroot/devel --initdb # 3 - download Fedora Release package. # If you do not want Fedora, download the correct *-release package and use it # on step 4. There are examples on the references. $ yumdownloader --destdir=/tmp fedora-release # 4 - Install downloaded Fedora release inside chroot $ sudo rpm --root /chroot/devel -ivh /tmp/fedora-release*r...
