Overview

The SCEC Broadband server is a computing resource with the Broadband Platform platform pre-installed and configured. Access to this server is by request, and requires a login which is provided once your account has been activated.

If you encounter any problems with the SCEC Broadband Server, or to request access, please contact software@scec.org.

Proposed Virtualized Server Software Stack

To facilitate migrating our broadband server configuration, we will use a virtualized version of the system, with a host OS the runs the hypervisor, and a guest OS which we use to perform software development.

Based on our use of KVM, the resulting system will be considered a type 2 hypervisor system.

Host OS that include KVM

We want a recent version of CentOS as the Host OS

  • CentOS 8.2 (release date 6/2020)

Guest OS for Broadband Server Configuration

We want a recent version of Ubuntu as the Guest OS. This should have a full set of software developer tools.

  • Ubuntu 20.04 LTS (release date August 2020)

Configuration Details

  • SSH access
  • Accounts set up via LDAP server (Edric)

Software Stack

We would like these gnu compilers installed which are required to compile the Broadband Platform components:

  • gcc and gfortran (9.3.0)
  • fftw libraries (3.3.4 or later)


We would like the Python3 software installed using the Anaconda distribution tool. These are needed for running the Broadband Platform:

  • Python3 (3.8.2)
  • NumPy (1.17.4)
  • SciPy (1.3.3)
  • Matplotlib (3.1.2)
  • PyProj (2.5.0)
  • Numba (0.48.0)

Other tools/packages that should be installed on the system are:

  • wget
  • automake/autoconf
  • awk/sed
  • emacs
  • git

Filesystems

These are local filesystems on the Broadband Server and they should be backed up periodically.

  • /home/broadband-01 2.7T (2.5T Used, 0.2T Available)
  • /home/broadband-02 3.6T (3.0T Used, 0.6T Available)

These are remote filesystems available from the Broadband Server, needed for Broadband work:

  • /home/hypocenter-01 7.3T (2.6T Used, 4.8T Available, hypocenter.usc.edu:/hypocenter-01)
  • /home/rcf-104 286T (248T Used, 38T Available, almaak-07.usc.edu:/export/samfs-scec0/rcf-104)
  • /home/scec-00 286T (249T Used, 37T Available, almaak-07.usc.edu:/export/samfs-scec0/scec-00)
  • /home/scec-01 13T (8.1T Used, 3.9T Available, arc.usc.edu:/scec-01)
