[12] Directory-based coherence scheme overview diagram showing various actors and messages. As shown in the data flow diagram, the actors involved in a distributed shared memory system implementing directory based coherence protocol are: Requestor Node: This node is the processor who is requesting for a read/write of a memory block.
Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors). [ 1 ]
In all cases the computer monitors the depth and elapsed time of the dive, and many allow user input specifying the gas mixture. [32] Most computers require the diver to specify the mixture before the dive, but some allow the choice of mixture to be changed during the dive, which allows for the use of gas switching for accelerated decompression.
General arrangement, showing the key features. Trieste was designed by the Swiss scientist Auguste Piccard, based on his previous experience with the bathyscaphe FNRS-2.The term bathyscaphe refers to its capacity to dive and manoeuvre untethered to a ship in contrast to a bathysphere, bathys being ancient Greek meaning "deep" and scaphe being a light, bowl-shaped boat.

Most saturation diving is done offshore, in the vicinity of drilling and production platforms, or for salvage work, and requires precise positioning of the bell during the dive. In deep water this is usually done from a specialised diving support vessel, or a suitable vessel of opportunity on which a saturation system has been temporarily ...
A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp, as well as additional ...
Diver Ralph Wilbanks located the wreck in April 1995 while leading a NUMA dive team originally organized by archaeologist Mark Newell and funded by novelist Clive Cussler, [36] who announced the find as a new discovery [37] and first claimed that the location was in about 18 ft (5.5 m) of water over one mile (1.6 km) inshore of Housatonic, but ...
