Specifications

During 2009-2012, the setup was the following.

From an end-user perspective:

• each machine hosts an Intel Pentium Dual-Core processor (2 x E2180 @ 2.00GHz);
• memory: 2GB for each machine.

More specifically:

• each of the client machines has the following specs: Intel Desktop DG965SS motherboard (info1, info2); Intel DualCore E2180 CPU @ 2 GHz with cache 1 MB; 2 x RAM 1GB DDR2 677 MHz; rackmount 19" 2U case from Chieftec (UNC-210S-B), with ATX 300W power supply;
• the server machine has similar specs plus Intel PRO 1000GTLP/ENet gigabit ethernet card; 2 x WD2500JS 250GB SATAII 8MB disks for software RAID-1.

Additional setup

Other libraries, installed with Ubuntu packages

These packages were installed with sudo apt-get install:

 libgtk2.0-dev libgtkmm-2.4-dev libglademm-2.4-dev glew-utils libglew1.5-dev libglut-dev git-core

OpenCV:

 libcv-dev libhighgui-dev libcvaux-dev

System-wide libraries and repositories

YARP

Presently (November 2010), the yarp2 SVN repository is installed under user yarp (with sudo make install), last updated on 13-July-2010. <-- change this policy?

iCub

Presently (November 2010), the iCub SVN repository is installed under user icub (with sudo make install), last updated on 13-July-2010. <-- change this policy?

There was a conflict with iKin, which could not find libipopt.so.0, but it is now fixed thanks to setting the environment variable

 LD_LIBRARY_PATH=/opt/Ipopt-3.5.5-linux-x86_32-gcc4.2.4/lib/

into /home/icub/.bash_env.

One module has been disabled in the CMakeList.txt file, because it was not compiling properly: crawling.

User repositories

you should add <iCub>/bin to your PATH by editing your ~/.bashrc like this:

 PATH=$PATH:~/iCub/bin/
 ICUB_DIR=~/iCub/ <-- needs to change
 export ICUB_DIR
 ICUB_ROOT=$ICUB_DIR
 export ICUB_ROOT

You should also edit ~/.bash_env adding these lines:

 export ICUB_DIR=$HOME/iCub <-- needs to change
 export ICUB_ROOT=$ICUB_DIR

this is needed when you connect non-interactively via ssh to a Cortex computer, for instance when execute a "yarp run ..." on a Cortex, from Chico2.

Be aware that Ubuntu 7.10 (the version currently installed on the cluster) has a conflict with iKin, specifically with iCub/conf/FindIPOPT.cmake (used by iKin): for now, in order to compile iKin, change the following line of FindIPOPT.cmake from

  SET(IPOPT_LIB   ${IPOPT_LIB} gfortranbegin gfortran)

to

  SET(IPOPT_LIB   ${IPOPT_LIB} gfortran)

Helper commands

These generic Linux commands should be written somewhere else, as they are not Cortex-specific

• Check the kernel: uname -m
• Check the file versions: file
• Set bash shell in /etc/passwd
• Check disk space: du –sh /home
• Check per-user processes: ps -U <user>
