Treat Fortran “real” variables as double precision
The gfortran, ifort, and pgf90 compilers can be instructed that variables declared as “real” should actually be stored and handled as double precision quantities. Details are at https://198.82.212.30/userguide/fortran_realsize/
Parallel COMSOL
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/.
How to install and use MPI4PY
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/ .
Classroom Presentations on High Performance Computing
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 a list of available presentations, refer to the document: Classroom Presentations. You may also be interested in the visualization presentations described in the document: Visualize This!.
For more information, contact Alana Romanella at aromanel@vt.edu.
Visualize This!
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 appopriate for a given class.
For more information, go to Visualize This! webpage, or refer to the Visualize This! brochure, or contact Nicholas Polys at npolys@vt.edu.
“Where’s LAPACK?”
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?”
Fall 2014 NLI Short Courses
In Fall of 2014, the Interdisciplinary Center for Applied Mathematics (ICAM) and ARC will offer a three-session short course on Parallel Computing with MATLAB as a part of the Virginia Tech Network Learning Initiatives (NLI) curriculum. The course will be taught by Dr. Eugene Cliff of ICAM in conjunction with Advanced Research Computing. Users can enroll through NLI here.
