Summer 2003 System Updates

• Account Information Page - The web-based account information page has been expanded and improved to give even more useful information about your CS accounts. Please see the Account Information FAQ Page for more information.

• Sun Server Upgrades - A number of the departmental Sun Servers were upgraded to new Sun Fire 280Rs, including whale (the sharkestra server), moose (the faculty/staff server), school (the sharkestra compute server), and rainier (the extreme server). These are dual processor systems with 8GB (moose and school) or 2GB (whale and rainier) of main memory. The old school (a 4 processor Sun E450 with 4GB of memory) replaced burrowww, giving that server double the processors and memory.

• Linux Server Upgrades - A new dual-processor 3.06GHz Intel Xeon system running Linux was added for general purpose computing needs. This system is named hagar and is available to anyone with with a sharkestra account. The Linux server running the Virus/Spam email scanner was also upgraded to a dual-processor 2.8GHz Dell 2650.

• Linux Cluster - An 8-node Linux cluster and Storage Area Network (SAN) were purchased with NSF grant funds. See the system notice for more details.

• Programming Tools Installed - The suite of C, C++, and Java programming tools from Parasoft Corporation are now available on the CS Sun and Linux systems. The Omnicore CodeGuide Java Integrated Development Environment (IDE) is also available on the CS Sun, Linux, and Mac OS X systems. These are highly sophisticated programming tools and environments and you are encouraged to take advantage of them. The Omnicore tool is made available through a site license purchased by the CS Department and the Parasoft tools through an IU-wide site license.

• LH115 Upgrades - The PCs in the LH115 classroom have all been upgraded to new Dell Optiplex GX 260s and are running in a multi-boot configuration of Windows, Linux, and DOS. The projector was also replaced with a new higher-resolution Hitachi CP-SX5600W LCD projector.

• Course Schedules - The web-based database of CS Course Schedules has been rewritten and improved to include a search feature. This allows you to search on the Course, Location, and Instructor fields for a given semester. This provides an easy way, for example, to generate a listing of the courses you are teaching which you could link to from your web homepage.

• New Laptop Interfaces - There are now wired network drops available in the Burrow (LH004), the Grad Lab (LH125), and LH035. See the Wired Network portion of the FAQ for more information. The wireless network is also still available just about anywhere in Lindley Hall.
