The Cray XT5 is an updated version of the Cray XT4 supercomputer, launched on November 6, 2007. It includes a faster version of the XT4's SeaStar2 interconnect router called SeaStar2+, and can be configured either with XT4 compute blades, which have four dual-core AMD Opteron processor sockets, or XT5 blades, with eight sockets supporting dual or quad-core Opterons. The XT5 uses a 3-dimensional torus network topology.
The XT5 family run the Cray Linux Environment, formerly known as UNICOS/lc. This incorporates SUSE Linux Enterprise Server and Cray's Compute Node Linux.
The XT5h (hybrid) variant also includes support for Cray X2 vector processor blades, and Cray XR1 blades which combine Opterons with FPGA-based Reconfigurable Processor Units (RPUs) provided by DRC Computer Corporation.
The XT5m variant is a mid-ranged supercomputer with most of the features of the XT5, but having a 2-dimensional torus network topology and scalable to 6 cabinets.
In the fall of 2008, Cray delivered a 1.3 petaflops XT5 system to National Center for Computational Sciences at Oak Ridge National Laboratories. This system, with over 150,000 processing cores, was dubbed "Jaguar" and was the second fastest system in the world for the LINPACK benchmark, the fastest system available for open science and the first system to exceed a petaflops sustained performance on a 64-bit scientific application.
Cray Inc. is an American supercomputer manufacturer headquartered in Seattle, Washington. It also manufactures systems for data storage and analytics.
Cray manufactures its products in Chippewa Falls, Wisconsin, where its founder, Seymour Cray, was born and raised. The company also has offices in St. Paul, Minnesota (the site of its original headquarters under Seymour Cray), and numerous other sales, service, engineering, and R&D locations around the world.
Several Cray supercomputer systems are listed in the TOP500, which ranks the most powerful supercomputers in the world. The number of Cray systems on the list varies from year to year.
The company's predecessor, Cray Research, Inc. (CRI), was founded in 1972 by computer designer Seymour Cray. Seymour Cray went on to form the spin-off Cray Computer Corporation (CCC), in 1989, which went bankrupt in 1995, while Cray Research was bought by SGI the next year. Cray Inc. was formed in 2000 when Tera Computer Company purchased the Cray Research Inc. business from SGI and adopted the name of its acquisition.
Bas-Lag is the fictional world in which several of China Miéville's novels are set. Bas-Lag is a world where both magic (referred to as "thaumaturgy") and steampunk technology exist, and is home to many intelligent races. It is influenced by the themes and tropes of multiple genres of science fiction, fantasy, and horror.
So far there have been three novels set in Bas-Lag. They are:
Additionally, the short story "Jack", featured in the 2005 collection Looking for Jake, is a Bas-Lag story.
Bas-Lag possesses a number of continents. Two landmasses, Rohagi and Bered Kai Nev, are named in the three novels, though numerous other landmasses and unique structures play important roles in the novels.
The exact proportions and geography of Rohagi are unknown. New Crobuzon lies about ten miles (16 km) inland from its eastern coast, which borders the Swollen Ocean. Immediately south of New Crobuzon is the Rudewood, beyond which lies the Mendican Hills. North of New Crobuzon, along the coast but separated by the Bezhek Mountains, are the ruins of Suroch. To the west, about a thousand miles from New Crobuzon and far beyond the Dancing Shoe Mountains, lies the four-hundred mile wide freshwater lake called Cold Claw Loch. The Loch connects with the vast, inland Cold Claw Sea, eight hundred miles to the north, via a natural channel called Cold Claw Sound. The Cold Claw Sea is talon-shaped, stretching eastward a great distance, almost connecting with the Swollen Ocean before curving southward for about two hundred miles, finally ending about seven hundred miles north of New Crobuzon. This southward curve is the Gengris, and is populated by the dangerous and unpredictable grindylow.
