摘要:
A multi-dimensional processor cell and processor array with massively parallel input/output includes a processor array having a plurality of processor cells interconnected to form an N-dimensional array. The system includes a first group of processor cells having 2N dimensionally adjacent processor cells. At least one input/output device is connected to a surplus data signal port of a second group of processor cells each having fewer than 2N dimensionally adjacent processor cells, for providing massively parallel input/output between the multi-dimensional processor array and the input/output device. The processor system also includes a front end processor for providing processor array instructions in response to application programs running on the front end processor. A processor cell controller, responsive to the processor array commands, broadcasts a sequence of processor cell instructions to all of the processor cells of the multi-dimensional processor array.
摘要:
A reconfigurable multi-dimensional processor array for processing multi-dimensionally structured data includes a plurality of processor cells arranged in N dimensions and having a plurality of N-1 dimensional processor subarrays. Each of the processor cells has 2N data signal ports operative for forming data signal paths for transmitting and receiving data to and from 2N adjacent processor cells or data communication devices. Each of the N-1 dimensional processor subarrays includes a selected group of processor cells coupled to fewer than 2N other processor cells or data communications devices. Each of the selected group of processor cells includes at least one uncoupled data signal port. An intermediary connection couples selected uncoupled data signal ports from at least a first N-1 dimensional processor subarray to selected uncoupled data signal ports from at least a second N-1 dimensional processor subarray, to form selected data signal paths between selected processor cells within the at least first and second N-1 dimensional processor subarrays.
摘要:
In a first aspect, a method of synchronizing at least two computing elements 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, monitoring the computing elements to detect the production of a selected signal by one of the computing elements, waiting for the other computing elements to produce a selected signal, transmitting equally valued time updates to each of the computing elements, and updating the clocks of the computing elements based on the time updates.In a second aspect, fault resilient or fault tolerant computers are produced by designating a first processor as a computing element, designating a second processor as a controller, connecting the computing element and the controller to produce a modular pair, and connecting at least two modular pairs to produce a fault resilient or fault tolerant computer. Each computing element of the computer performs all instructions in the same number of cycles as the other computing elements.Computer systems include one or more controllers and at least two computing elements. Means are provided for intercepting I/O operations by the computing elements and transmitting them to the one or more controllers.

摘要:
Fault resilient or fault tolerant computers are produced by designating a first processor as a computing element, designating a second processor as a controller, connecting the computing element and the controller to produce a modular pair, and connecting at least two module pairs to produce a fault resilient or fault tolerant computer. Each computing element of the computer performs all instructions in the same number of cycles as the other computing element. The controllers provide input/output processings for the computing elements, as well as monitor their operations to detect errors, and control operation of the computing elements in response to the detected errors.
摘要:
The effects of I/O race conditions caused by asynchrony between processors concurrently executing the same software and I/O devices are eliminated by executing an application program and a first associated operating system with firs processors, and executing an I/O processing program and a second associated operating system with an I/O processor. Memory requests from the application program or the first associated operating system are processed with the first processors, and memory requests from the application program to memory addresses associated with I/O devices are trapped and transmitted to the I/O processor. The I/O processor then performs the trapped memory requests with the I/O processing program after waiting for the identical request to be received from each of the first processors to eliminate the effects of race conditions caused by asynchrony between processors concurrently executing the application program or the first associated operating system and I/O devices. I/O requests may be trapped and performed by the I/O processor for the same purpose.
