Title:
故障から立直りが速い/故障に対する耐性がある計算処理
Document Type and Number:
Japanese Patent JP3679412
Kind Code:
B2
Abstract:
A method of synchronizing at least two computing elements (CE1, CE2) that each have clocks that operate asynchronously of the clocks of the other computing elements includes selecting one or more signals, designated as meta time signals, from a set of signals produced by the computing elements (CE1, CE2), monitoring the computing elements (CE1, CE2) to detect the production of a selected signal by one of the computing elements (CE1), waiting for the other computing elements (CE2) to produce a selected signal, transmitting equally valued time updates to each of the computing elements, and updating the clocks of the computing elements (CE1, CE2) based on the time updates. In a second aspect of the invention, fault resilient, or tolerant, computers (200) are produced by designating a first processor as a computing element (204), designating a second processor (202) as a controller, connecting the computing element (204) and the controller (202) to produce a modular pair, and connecting at least two modular pairs to produce a fault resilient or fault tolerant computer (200). Each computing element (202, 204) of the computer (200) performs all instructions in the same number of cycles as the other computing elements (202, 204). The computer systems include one or more controllers (202) and at least two computing elements (204).
