Connecting to NERSC
NERSC's resources can be accessed using SSH and related tools, grid tools, and via the web. This section explains how to connect to NERSC interactively, how to transfer data, and how to get help when your network connection is slow.
Introduction NERSC users will be required to use Multi-Factor Authentication (MFA) beginning in Allocation Year 2019. MFA provides greater protection than regular passwords against phishing and other modern threats to your digital security. With NERSC's MFA, you authenticate using your NIM password plus a "one-time password" (OTP). As the name implies, you can use an OTP only once. You can find instructions for configuring and using MFA below. Currently MFA logins are supported for ssh to NERSC… Read More »
Introduction X-Windows allows you to display remote applications on your local computer screen. X-Windows follows the client-server architecture. Normally, the X server runs on the users desktop/laptop computer, while the X client (for example a GUI application) runs on the remote server. The X Client displays itself on the X Server. Using NERSC NX Service to Improve X Performance NX is a computer program that handles remote X Window System connections. It can greatly improve the performance of… Read More »
NX is a computer program that handles remote X Window System connections. It can greatly improve the performance of the X Windows, to the point that it can be usable over a slow link such as a dial-up modem. NX also provides sessions, which will allow a user to disconnect from the session and reconnect to it at a later time, while keeping the state of all running applications inside the session. This gives users a virtual desktop that's running at NERSC. Read More »
In this ESnet Network Performance Knowledge Base you will find information on how to make your wide area data transfers go faster. The goal of this site is to help you maximize your wide-area network bulk data transfer performance by tuning the TCP settings for your end hosts and by using file transfer tools that are designed to maximize network throughput.
