Cray XE6

The Cray XE6 (codenamed Baker during development) is an enhanced version of the Cray XT6 supercomputer, officially announced on 25 May 2010. The XE6 uses the same computer blade found in the XT6, with eight- or 12-core Opteron 6100 processors giving up to 3,072 cores per cabinet, but replaces the SeaStar2+ interconnect router used in the Cray XT5 and XT6 with the faster and more scalable Gemini router ASIC. This is used to provide a 3-dimensional torus network topology between nodes. Each XE6 node has two processor sockets and either 32 or 64 GB of DDR3 SDRAM memory. Two nodes share one Gemini router ASIC.

The XE6 runs the Cray Linux Environment version 3. This incorporates SUSE Linux Enterprise Server and Cray's Compute Node Linux.

XE-class submarine

Six XE-class midget submarines (HMS XE1 to XE6) were built for the Royal Navy during 1944. They were an improved version of the X Class midgets used in the attack on the German battleship Tirpitz.

They carried a crew of four, typically a lieutenant in command, with a sub-lieutenant as deputy, an engine room artificer in charge of the mechanical side and a seaman or leading-seaman. At least one of them was qualified as a diver.

In addition to the two side charges (each of which contained two tons of amatol explosive), they carried around six 20-pound limpet mines which were attached to the target by the diver.

They and their depot ship HMS Bonaventure arrived at Labuan in July 1945. Four of them managed to see action before the war ended.

Operations Sabre and Foil

These operations, carried out in July 1945, were intended to cut the undersea telephone cables connecting Singapore, Saigon, Hong Kong and Tokyo. The intention was to oblige the Japanese to use radio and render themselves open to message interception.

Cray

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

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.

The Bas-Lag novels

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.

Geography

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.

Rohagi

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.
