Many user programs reference the BLAS (Basic Linear Algebra Subprograms) library. The ARC software library does not include a standalone compiled version of this library. However, the BLAS are available in the Intel MKL library, which contains automatically tuned versions of every BLAS function, offering better performance than a user could get from a source code library of BLAS.

Many user programs reference the BLAS (Basic Linear Algebra Subprograms) library. The ARC software library does not include a standalone compiled version of this library. However, the BLAS are available in the ATLAS library, which contains automatically tuned versions of every BLAS function, offering better performance than a user could get from a source code library of BLAS.

All users need two factor authorization (2FA) to access VT ARC systems.
Details about setting up and using 2FA are in:
If you are using the DUO app on a cell phone for your 2FA, then you
can click on the key next to "VT", and a code will pop up. Then, when
you log into any 2FA system, you can follow your password by a comma and
then the code:
This alternative is useful for situations where cell phone service is
an issue, or for dealing with systems with a fast timeout, such as ETX.
The MPI4PY package allows Python programs to run in parallel under MPI. ARC has not installed this package, but interested users can do so. Installation and usage instructions are posted at https://secure.hosting.vt.edu/www.arc.vt.edu/userguide/mpi4py/ .
Any user interested in the TensorFlow machine learning system can
find instructions for installing and using the package at
External users of Virginia Tech ARC systems must switch to sponsored
accounts and shift their data files!
After 30 July 2017, a two factor authorization (2FA) scheme will be
necessary in order to access VT ARC systems. In turn, the
two factor authorization requires having a Virginia Tech PID.

Instructors of classes with a computational component can request a presentation on selected topics by an ARC computational scientist.
Topics include overviews of various parallel programming methods, machine learning and data science, visualization, and certain software packages. The level and scope of a presentation can be adjusted in advance, in consultation between the instructor and the ARC presenter.
Because our staff are small in number, and busy supporting the ARC systems, we can only respond to a limited number of presentation requests at any one time.
For more information, contact Alana Romanella at firstname.lastname@example.org.
Visualize This! is a classroom outreach program that shows students how to enrich their work with visualization.
Staff members from the Visualization Group at Advanced Research Computing (ARC) have prepared visualization presentations that last one class period. They are also eager to work with the instructor in advance, creating a customized presentation that focuses on topics and data appopriate for a given class.
Users of Virginia Tech's ARC computing clusters know that, if they want to find information about installed software, they only have to go to the main ARC webpage https://secure.hosting.vt.edu/www.arc.vt.edu/ , and then on the menu bar choose RESOURCES and from that menu select SOFTWARE. This produces an alphabetical list of the more than 250 installed software packages, including the locations and version numbers. But the package listed immediately after lame is LBPMWIA, and as more than one perplexed user has remarked, "Where's LAPACK?"
