There are a number of CVS clients available for Windows and Mac, and they fall in and out of development on a regular basis. Mac OSX does have a CVS command line client available using "Homebrew". See the Homebrew website for more information. There may also be a number of GUI based clients available, searching using your favorite search engine should provide the most up-to-date results.
Yes, but access is limited to within the RCE only. Create or log in to your NX session and navigate to phpmyadmin.hmdc.harvard.edu. Log in to phpMyAdmin using your database credentials. Make sure the proper host is selected in the drop down. If you don't know your host, check the email that was sent to you when you requested the database.
When running an RCE Powered Application -- for example an RCE Shell -- you have the opportunity to reserve a requested amount of system memory. Unfortunately, the Java JRE is not aware of the resource limit you have set, and will try (and fail) to grab as much of the system memory as is free.
To correct this behavior, you can set the shell environment variables JAVA_OPTS and _JAVA_OPTIONS before launching your java application. These values must be set within the shell that launches your java application, so it may be helpful to set these values and run your java app from within a single interactive RCE Powered Shell, or to create a shell script that sets these values and then runs your java app.
For example, to restrict the Java JRE heap memory allocation to 1GB initially and a maximum size of 2GB, set the variables as follows:
Unfortunately, at this time, ArcGIS remains a Windows-only product. As the RCE is based on Linux, we're currently unable to provide this software. Students and faculty can visit the following pages for obtaining and using ArcGIS:
If you were redirected here from the RCE, you may have been trying to install a package using apt-get. This is a package manager for Debian-based systems, and isn't compatible with the RCE. If you need assistance with installing additional software that isn't available on the RCE, please contact us (or by phone: 617-495-4734) for support!
The commands below will help you exit an RCE job from a terminal if the application window has disappeared, or you need to exit it and do not have access to your NX session. This can be accomplished by using an ssh client and connecting to rce.hmdc.harvard.edu, or opening a terminal window in the RCE.
The same commands can be used If you are running into an error starting a new RCE job due to too many CPU's in use, you need to terminate your jobs that were tied to an old nx session. The commands that are highlighted below should enable you to remove these old jobs.
Run this command to see your jobs: condor_q -pool cod6-head.priv your_username ID OWNER SUBMITTED RUN_TIME ST PRI SIZE CMD job_id username date_&_time run_time R 0 0.0 application_name
The RCE is free to use for qualified individuals in the pursuit of social science research, within certain limits.
If your needs exceed the capacities of the shared RCE environment, we can work with you to establish dedicated RCE resources for your exclusive use. If you are planning a large project, please contact us prior to your grant application so that we can assist in budgetary estimation.
