Added details about giant printer
The '''CAD and Visualization Laboratory''' or '''CVL''' is a computer lab running mainly [[w:CentOS|CentOS]] machines maintained by the [[Bradley Department of Electrical and Computer Engineering]]. It is located in 432 [[Whittemore Hall]]. Access is through a keypad, the number to which can be obtained through official channels from ECE systems administrator [http://search.vt.edu/search/person.html?person=1181337 Branden McKagen]. Disk quotas are enforced when home folders become unreasonably large, unless you have a good reason to need the space. The CVL cluster is available via ssh to account holders on <code>cvl.ece.vt.edu</code> and has MPI, MATLAB, Cadence, and [https://computing.ece.vt.edu/wiki/Software_Packages_and_Programs other software ] installed. Virginia Tech users can obtain a central authentication account for all CVL machines using the [https://computing.ece.vt.edu/~jkh/Session/ automated account creation tool].
== Physical Resources in the CVL ==
* A printer available at <code>socket://172.16.12.1</code> (only accessible from machines behind the CVL router). This uses the Dell M5210 Foomatic/Postscript driver, which is available in <code>/software/Dell_5210n.ppd</code> on CVL machines.
* A microscope
* A large-format Epson 9800 printer for research groups to print posters and CAD drawings (located offsite, follow [https://computing.ece.vt.edu/wiki/Document_Printing_(Posters,_CAD_drawings,_photographs) the posted instructions] for usage).
== Compute Clusters ==
** Remote access available through ssh to <code>cvl.ece.vt.edu</code>. Individual nodes are <code>cvlXX.ece.vt.edu</code>
** MPI is installed, qsub can be used to parallelize things
** X11 is also installed, so <code>ssh -X cvl.ece.vt.edu</code> can be used to remotely run GUI applications.
* 32-node blade cluster
** 16 nodes with 2x Quad-Core AMD Opteron(tm) Processor 2350 2GHz, 20 GBytes RAM, 1 Gbit/sec ethernet (<code>cluster[01-16]</code>)
** This cluster does not have global IPv4 addresses, so you must ssh into other machines first to access this.
* Both clusters use a shared file storage system and central authentication, so home directories will persist between nodes.
* [https://computing.ece.vt.edu/wiki/Software_Packages_and_Programs Lots of software] is installed on the CVL machines.
For larger jobs, the [http://www.arc.vt.edu Advanced Research Computing] machines may be more appropriate.
