A COMSOL batch job can run in parallel, using multiple nodes or processors. Information on how to automatically set the appropriate COMSOL command line parameters for parallel execution is available, including an example script, athttps://secure.hosting.vt.edu/www.arc.vt.edu/userguide/comsol/.
ARC will offer many free classes on scientific computing, sponsored by Network Learning Initiatives (NLI) and held in room 1100 Torgersen. NLI encourages you to register for these classes through their web site https://nli.tlos.vt.edu, but unregistered auditors are welcome to sit in.
For a list of dates, times, and titles for the classes, refer to

A short discussion of licensed software installed on ARC clusters has been posted at :
Many user programs reference the LAPACK (Linear Algebra PACKage) library. The ARC software library does not include a standalone compiled version of this library. However, a highly tuned version of the LAPACK library is included in the ATLAS library (along with the BLAS, FFT functions, and many others). The optimized versions of LAPACK functions available through the MKL library typically offer better performance than a user could get from a source code library of LAPACK.
