New requirement: must use Harvard VPN to access the RCE

April 18, 2019

We're changing the way RCE users connect to the RCE. Following the changeover in late May, you'll need to connect to Harvard's VPN in order to use the RCE, whether you are connecting via NoMachine (NX), or SFTP or SSH. In order to connect to VPN, you'll need to claim your HarvardKey and set up two-factor authentication (the DUO app is recommended, but you can also use SMS or a phone call for authentication).

Stata-MP 14 CPU increase

We've recently updated our Stata licenses so that Stata-MP 14 can accomodate more than 4 CPUs at a time. Although the theoretical maximum is now 64, cluster availability will usually allow much less.

Please note, Stata 13 is still limited to 4 CPUs, and Stata-SE is still limited to 1 CPU.

Default Path Change

August 12, 2016

The default PATH for command-line RCE Shell will no longer include the current directory by default. This change ensures that only applications in known, trusted locations are executed.
