Abstract: Systems and methods are provided to enable parallelized multiply-accumulate operations in a systolic array. Each row of the systolic array can include multiple busses enabling independent transmission of inputs along the respective bus. Each processing element of a given row-oriented bus can receive an input from a prior element of the given row-oriented bus, and perform arithmetic operations on the input. Each processing element can generate an output partial sum based on the arithmetic operations, provide the input to a next processing element of the given row-oriented bus, without the input being processed by a processing element of the row located between the two processing elements that uses a different row-oriented bus. Use of row-oriented busses can enable parallelization to increase speed or enable increased latency at individual processing elements.

Abstract: Described herein are systems and techniques for an event handling system capable of distinguishing between application or user-specific events and system-wide events. The described system may be further capable of suppressing event notifications associated with application or user specific events and escalating system-wide events. In some embodiments, the system may identify an origination source for a number of event trigger. The system may determine whether a number of trigger events associated with any particular origination source are over a threshold number of trigger events. Upon determining that the event is an application or user specific event, then the system may suppress a potential escalation of the event.
