Embodiments of an interconnect apparatus enable improved signal integrity, even at high clock rates, increased bandwidth, and lower latency. In an interconnect apparatus for core arrays a sending processing core can send data to a receiving core by forming a packet whose header indicates the location of the receiving core and whose pay load is the data to be sent. The packet is sent to a Data Vortex switch described herein and in the patents incorporated herein. The Data Vortex switch is on the same chip as an array of processing cores and routes the packet to the receiving core first by routing the packet to the processing core array containing the receiving processing core. The Data Vortex switch then routes the packet to the receiving processor core in a processor core array. Since the Data Vortex switches are not crossbar switches, there is no need to globally set and reset the Data Vortex switches as different groups of packets enter the switches. Mounting the Data Vortex switch on the same chip as the array of processing cores reduces the power required and reduces latency.

Method and apparatus for improved data transfer between processor cores

Techniques are disclosed relating to parallel computing. In some embodiments, fine-grained data communication facilitates operations on large data sets such as multiplication of a sparse matrix by a vector. In this example, a first data set (the matrix) and a second data set (the vector) are distributed across multiple processing nodes. Performance of the overall multiplication operation may require communication of data among the processing nodes. In various embodiments, fine-grained communication of this data may reduce processing times and/or power consumption by avoiding congestion.
