The evolution of computers has led to the current generation of powerful, RISC-based workstations. These systems are often rich of interesting architectural features and peripheral devices. Very often, they also run multitasking, multiuser operating systems which make almost complete use of the available hardware. This makes it very hard to use these systems for the lab classes of a computer ar...

Andrew Witkowski, Felipe Carifio, and Pekka Kostamaa NCR/Teradata Advanced Concepts Laboratory (TACL) 100 N. Sepulveda Blvd. El Segundo, CA 90245 Abstract The iVCR 3700 is our next-generation general purpose computer. Its design benefited from 10 years of Teradata DBC/1012 industrial experience, with which we hold a 70% market share in commercial VLDB applications. The NCR 3700 will be sold as ...

Today's high-performance RISC microprocessors have been highly tuned for integer and oating point application performance. These architectures have paid less attention to operating system requirements. At the same time, new operating system designs often have overlooked modern architectural trends which may unavoidably change the relative cost of certain primitive operations. The result is that...
