    摘要: A method to exchange data in a shared memory system includes the use of a buffer in communication with a producer processor and a consumer processor. The cache data is temporarily stored in the buffer. The method includes for the consumer and the producer to indicate intent to acquire ownership of the buffer. In response to the indication of intent, the producer, consumer, buffer are prepared for the access. If the consumer intends to acquire the buffer, the producer places the cache data into the buffer. If the producer intends to acquire the buffer, the consumer removes the cache data from the buffer. The access to the buffer, however, is delayed until the producer, consumer, and the buffer are prepared.

    摘要: A data center includes a plurality of computing units that communicate with each other using wireless communication, such as high frequency RF wireless communication. The data center may organize the computing units into groups (e.g., racks). In one implementation, each group may form a three-dimensional structure, such as a column having a free-space region for accommodating intra-group communication among computing units. The data center can include a number of features to facilitate communication, including dual-use memory for handling computing and buffering tasks, failsafe routing mechanisms, provisions to address permanent interface and hidden terminal scenarios, etc.

    摘要: Conflict-free vector access of any constant stride is made by preselecting a storage scheme for each vector based on the accessing patterns to be used with that vector. A respective storage scheme for each vector, for example, is selected to provide conflict-free access for a predetermined stride S. The respective storage scheme involves a rotation or permutation of an addressed row of corresponding memory locations in N parallel modules in main memory. The amount of rotation or permutation is a predetermined function of the predetermined stride S and the row address. The rotation is performed by modulo-N addition, or the permutation is performed by a set of exclusive-OR gates. For a system in which N is a power of 2 such that n=log.sub.2 N, the predetermined stride S is factored into an odd component and an even component that is a power of 2. The factorization is easily performed by a shift and count procedure, a shifter and counter, or a priority encoder. The amount of rotation or permutation is a predetermined function of the even component and the row address, and is preferably obtained by selecting a field of the row address in accordance with the maximum of s and n, and masking the selected field with a mask generated from the minimum of s and n.
