US 2019/0294520 A1 · PACKET FLOW TRACING IN A PARALLEL PROCESSOR COMPLEX

Abstract

In one example implementation, a computer-implemented method includes receiving, at a parallel processor complex, a task to be executed by the parallel processor complex. The parallel processor complex includes a trace processor and a plurality of task execution processors, each of the plurality of task execution processors having a plurality of trace buffers associated exclusively therewith. The method further includes creating, by the trace processor, a trace entry by allocating an element from a shared queue. The method further includes loading, by the trace processor, the trace entry into a common trace buffer. The method further includes loading, by the trace processor, the trace entry into one of the plurality of trace buffers based at least in part on an interface identifier and a queue pair index record. The interface identifier identifies the one of the plurality of task execution processors with which the trace entry is associated.
