Sam Houston the Lab’s Site Access Office puts a personal and friendly face on the process of getting an LDAP password for new Lab employees. In the past, new employees called the Help Desk to get their password, but the Help Desk had no way of verifying callers’ identities. Today passwords are distributed face to face at the same time that employees receive their badge, making distribution more secure and giving employees immediate access to email. Read more.
Increasing cyber security threats and regulatory requirements have led the LBLnet team to add new defenses to the Lab's wireless networking facilities. They've stepped up protection, particularly against worms and viruses aimed at Windows systems on the wireless network. Read more.
One useful feature of Mozilla that makes web browsing more convenient is tabbed browsing, which allows multiple web sessions to run in the same window. You can simply switch to another session by clicking on its tab. To learn more about tabbed browsing and how to located missing email attachments, read more.
Don't Fall for the Latest Internet Hoax
The latest Internet hoax is in the form of what looks like a message from the National Personnel Records Center (NPRC) in St. Louis announcing that NPRC is planning to destroy all paper military records. Several web sites also have postings with this alleged destruction of military records. A NPRC spokesperson denied that they plan to destroy any of their records. Beware of this hoax!
ESnet will hold a workshop in Auditorium 66 from Oct. 27 - 29 to help plan the future directions for ESnet Collaboration Services. ESnet Collaboration Services provides a number of online services aimed at improving collaboration among researchers at the national laboratories and universities served by ESnet. Read more.
New Scientific Clusters
Where it all begins
These newly-arrived boxes are clusters waiting to be assembled by the Scientific Cluster Support (SCS) team. On the left are components for a planned 256-processor Infiniband cluster belonging to Earth Sciences. It will be used to develop solutions to large scale forward and inverse modeling problems based on electromagnetic and seismic wave fields to better characterize complex geological systems. On the right are boxes that will soon be a 72-processor Myrinet Linux cluster for Marvin Cohen and Steven Louie in Material Sciences. This cluster will be running first-principles quantum-mechanical simulations that will predict and understand the fundamental properties of exotic materials with potential technological applications.
Up and running
These are twin clusters for Chemical Sciences. On the left is a 46-processor Linux cluster, which belongs to the William Lester Group, went into production this month. It’s used to develop the Quantum Monte Carlo (QMC) method or application to the electronic structure of atoms and molecules. On the right is a 42-processor Opteron cluster is being installed for Martin Head-Gordon. His group will use this cluster to perform electronic structure calculations on molecular systems ranging from combustion-related radicals to nanomaterials, and for the development of new algorithms for such calculations.
