RTDC Computers


We provide and maintain 6 Linux 64 bit workstations for use by R&G staff and visitors, and support the software packages AIPS, MIR, MIRIAD and CASA. Ask holly.thomas@cfa.harvard.edu or your R&G contact for an account.

These machines can be found in room M-342 on the 3rd floor of 160 Concord Ave.

See the current status of these machines here (updated every 15 minutes).

RGLINUX11 repurposed for AWS
Following disk failures, and given its sub-optimal performance specs, RGLINX11 has been repurposed as a gateway machine for an AWS (Amazon Web Services) storage area. Over the next few months we will be testing the use of AWS as a repository for archival SMA data and long term storage for user data.

Virtual machines
Our VMs, rtdc8vm and rglinux12vm, pull their software from Hilo, whilst the home directories are RTDC. This gives users the option to use Hilo installations while being able to process data locally. RGLINUX12 is still available for use although it shares memory with rglinux12vm. Note that as these VMs have no physical disks, reduction areas must be mounted from other computers, and it is possible to mount the reduction area from your home directory in Hilo (SMA users only).


Printers

There are four communal printers on the 3rd floor of 160 Concord Ave which are available from the RTDC computers.
