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 with a PID can obtain a central authentication account for all CVL machines using the [https://computing.ece.vt.edu/accounts/ automated account creation tool].
== Physical Resources in the CVL ==
The lab in 432 Whittemore Hall contains:
* <strike>9 workstations (formerly <code>cvlwsXX.ece.vt.edu</code>), most of which have CentOS, Core 2 Duo, 4 GB memory, and dual monitors</strike>
* 9 8 new workstations (cvlwsXX), with CentOS 6, dual quad-core Xeons, 16 GB memory, dual monitors, and dual NVIDIA graphics cards* 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. It's currently broken.
* 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 ==
* <strike>15</strike> 14-node old cluster(also known as "the CVL cluster" or "ghetto-cluster")
** Each has Intel(R) Pentium(R) D CPU 3.00GHz CPUs, 8 GBytes RAM, 1 Gbit/sec ethernet
** 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.
* <strike>32</strike> 31-node blade cluster(the new cluster, or the Beast 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>)
** 16 nodes with 2x Quad-Core (8 threads) Intel(R) Xeon Processor E5620 2.40 GHz, 24 GBytes RAM, 1Gbit/sec ethernet (<code>cluster[17-32]</code>)
* <code>prometheus.ece.vt.edu</code>, an off-the-shelf parallel computing cluster
* VTLUUG servers, including <code>wood</code> (a VM host) and <code>sunway</code> (a 19-node Pentium 4 cluster)
* <code>godel</code>, a research machine with a massive amount of cores
* A LAMP server
