To access the Shared Computing Cluster<\/a> (SCC), you must have an SCC account as a result of being a member of a Research Computing project<\/a> active on the SCC; more limited access is also available through a Linux Virtual Lab<\/a>\/scc-lite account. These accounts are separate from a general Boston University (BU) computing account. Having a BU Kerberos username and password<\/a> does not automatically give you access to the SCC.<\/p>\n Once you do have<\/b> your SCC account, you can log in to the machines listed below using your BU login name and Kerberos password. There are two ways to access the SCC. The newer and generally recommended way is using SCC OnDemand, using just your web browser. To do this go to scc-ondemand.bu.edu<\/b><\/a> – there is documentation on SCC Open OnDemand available<\/a>. The second, older way to access the SCC is using a separate program called an ssh<\/a> client to login to one of the machines listed below. Instructions on connecting to the SCC using SSH for various operating systems are here<\/a>. Duo Two-Factor Authentication<\/a> is also required for both of these ways of accessing the SCC.<\/p>\n Your usage of the SCC must abide by the BU Acceptable Use of Computing Services Policy<\/a> and the BU Information Security Policy<\/a>.<\/p>\n Researchers using the SCC must also abide by the guidelines of the Office of Reseach Compliance<\/a> at Boston University.<\/p>\n When you first receive an SCC account<\/a>, you should receive email with instructions on how to access your account using your BU login ID and Kerberos password; external users only will get an email letting them know their new BU login ID and letting them set up their BU Kerberos password. Only your BU Kerberos password can be used to access our password-restricted web materials, including SCC OnDemand<\/a>.<\/p>\n If you forget your BU Kerberos password, you can change it here<\/a>. <\/p>\n With your Kerberos password, you can also change your shell<\/a>.<\/p>\n There are two ways to access the SCC, both of them require using Duo Two-Factor Authentication<\/a>:<\/p>\n If you follow the above steps properly, you should also be able to display graphics on your machine, such as running MATLAB’s GUI. You can test this by running the command As a rule, the graphics performance offered by the OnDemand web interface to the SCC will be drastically superior to that achieved by X Windows. OnDemand is also generally significantly easier to use.<\/p>\n Use of a VPN (Virtual Private Network)<\/a> is generally not necessary for using the SCC although it may make things more convenient for those using \n
