I am happy to announce that our NoMachine NX4 infrastructure has matured into a production-ready product. Administrators and support staff from the HMDC Operations team will begin migrating users individually from NX3 to a modern NX4 based desktop.
While troubleshooting an issue with an independent RCE node, a configuration change caused NX sessions to be interrupted. If you are reconnecting to your lost NX session, you should now be able to resume the previous session. Please contact email@example.com if you had cluster jobs running and are unable to resume your NX session. SSH logins should not have been affected.
There was an unplanned outage today (Wed May 21) at 5pm lasting approximately until 5:15pm. This was caused by a misconfiguration of DNS. This issue has now been resolved. We apologize for any confusion or inconvenience this caused. If you have any questions or concerns, please contact us at firstname.lastname@example.org. Thank you.
HMDC announces the BETA release of NoMachine NX4 powered virtual desktops for the Research Computing Environment (RCE). The NoMachine NX4 BETA infrastructure provides both a web interface as well as a full featured desktop client featuring printer and storage sharing. NoMachine NX4 allows you to run interactive and batch jobs on the RCE cluster from anywhere -- your tablet, desktop or web browser -- while also providing the ability to copy files directly from your desktop or USB storage into the RCE with ease.
At 12:30 today we updated to version 12 of StatTransfer. You can use StatTransfer locally by going to the Mathematics menu, or you can run it on an RCE Powered node. There is also a command line version, to use the CLI version simply type `st` at a command prompt.
We also made some minor fixes to a few applications that spawned terminals when they started, the fix keeps the unnecessary terminal from starting. The batch watch utlility was also fixed. If you choose, email is now sent upon batch job completion.
Due to an exploit in the openssl package installed in the RCE we pushed out a workaround this morning at 09:45. No users should have been affected by this change. If you are interested in the openssl exploit you can read more about it here: CVE-2014-0160
The Harvard-MIT Data Center at IQSS is proud to announce the next major version of the Research Computing Environment.
The RCE offers a centralized place in which to store data, and collaborate on social science research analysis. The newest version is a major overhaul of the environment, making new software and tools available to our users. Known as RCE6, it is based on Enterprise Linux 6, and built on a new Puppet infrastructure to allow for flexible configuration and rapid feature updates. Read more about Introducing the New RCE
