CSAR staff have access to three ASCI supercomputers:
In addition, CSAR staff may use:
The DOE now allows access to US Citizens and permanent residents only.
For an account on any of the ASCI machines, get in touch with our local Point-of-Contact, William Dick, (w-dick@uiuc.edu). Fill out an Intersite Unclassified Guest Account Request Form.
Print out the blank form on this Web page, and fill in section I. The "Guest Site Name" is University of Illinois; The "Guest Organization" must be one of: Structures and Materials, Fluid Dynamics, Combustion, Computer Science, or Administration. We have no assigned "Guest Site DCE Name". The Host Access Information depends on which Lab's facilities (SNL, LANL, or LLNL) you are applying to use. The ASCI Alliance contacts are given on the Request Form Web page (not the blank form).
Graduate students and Postdocs should have their faculty advisor fill out Section II (Approvals); CSAR investigators and professional staff can leave it blank.
Give the form to our local Point-of-Contact. You'll be given an account at the "host site" of your choice (SNL. LANL, or LLNL).
In addition, LANL requires you to have an account on their Integrated Computing Network (ICN). Our Point-of-Contact will interact with their Point-of-Contact to pass your user information to process the application. Our point-of-contact receives the passwords and forwards them to you.
The DOE Lab firewalls will refuse unencrypted telnet sessions. It is especially important that you never send your password unencrypted over any network where it might be "sniffed" by some hacker. There are two ways to use encrypted sessions:
The form of the ssh command is:
ssh [-l DOE_LAB_USERNAME] HOSTNAMEFor example, to open a session on ASCI Blue Mountain using ssh, I type:
bernoulli % ssh bluemountain.acl.lanl.gov Host key not found from the list of known hosts. Are you sure you want to continue connecting (yes/no)? yes Host 'bluemountain.acl.lanl.gov' added to the list of known hosts. Creating random seed file ~/.ssh/random_seed. This may take a while. rfiedler's password: ####### Last login: Thu Jan 22 11:17:14 1998 from sgiclass12.lanl.gov bluemountain %
The "Host Key" stuff appears only the first time you log in from a particular workstation. It simply adds your workstation's name to its database.
If you use the Kerberos 5 "k5init" command to get credentials, you will not have to type in your password each time you open a session.
There are commercial versions of ssh for Macs and PCs. If you wish to dial-up from home to work, you can connect to the internet (local call) and use ssh running on your Mac or PC to encrypt your sessions. Be sure that you do not telnet to a local workstation to use ssh runnning on that workstation! If you do, your password will be sent unencrypted over the phone line and over the network from the terminal server to the workstation; it will therefore be subject to "sniffing".
Please send your questions about ASCI Red and ASCI Blue Mountain to Robert Fiedler (rfiedler@uiuc.edu). The DOE labs wish to limit the number of questions they get from the ASCI Centers by providing training on each platform to a few people from each center, who will serve as a local knowledge base. These local contacts need to see the questions & answers so that DOE lab staff will not have to respond to the same inquires over and over.
