			== Mounting network folders ==

			The folder "database" on BlackHole is mounted automatically to /media/blackhole.
			For details, here is the content of /etc/fstab:

			#MATTEO: removed because it wouldn't work at startup: file systems are mounted before the network connection is available.

			The Cortex computation rack actually contains 7 machines:
			* 1 server that manages startup, shutdown and the file system of the clients;
			* 6 clients (named <code>cortex1</code>...<code>cortex6</code>) that run user processes.
			All clients numbered 1 to 5 mount the same file system. Therefore, performing changes in the file system of cortex[1-5] will reflect to all other four clients. Beware, though, that because of the way the file systems are mounted, there is some '''caching''' going on. This improves disk access performance, but strange phenomena might happen, i.e., after a file is modified and saved on one client, other clients can continue to see the old version of it for some time (probably less than one minute).
			The client <code>cortex6</code> is separate for now, because it runs a 64 bit Linux.

			For further details, see the [[Cortex setup]] article.

			From an end-user perspective:
			* each machine hosts an Intel Pentium Dual-Core processor (2 x [http://ark.intel.com/products/31733/Intel-Pentium-Processor-E2180-(1M-Cache-2_00-GHz-800-MHz-FSB) E2180] @ 2.00GHz);

			Presently (November 2010), the [[RobotCub software \| iCub SVN repository]] is installed under user <code>icub</code> (with <code>sudo make install</code>), last updated on 13-July-2010. <-- change this policy?

			There was a conflict with iKin, which could not find <code>libipopt.so.0</code>, 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 <code>/home/icub/.bash_env</code>.

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

			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)
