Abstract: A method, system and computer program product are presented for providing pseudo-random input test data to a test program. A seed value is generated and stored in a seed register. Using the seed value as an input, a pseudo-random input test value is generated by a Linear Feedback Shift Register (LFSR), and stored in a GPR within a processor core. Using the pseudo-random input test value from the GPR, a test program is executed within the processor core.

Abstract: A breakpoint packet is dispatched to a Network On A Chip (NOC). The breakpoint packet instructs one or more specified nodes on the NOC to place the specified nodes, or a core or hardware thread within a specified node, to execute in “single step” mode, in order to enable a debugging of a work packet that is dispatched to the specific node.

Abstract: A data processing system and method in a computer network are disclosed for improving performance of a link aggregation system included in the network. Parameters are established which are utilized to determine performance criteria of the link aggregation system. A performance of the link aggregation system is determined by determining the performance criteria. The performance of the link aggregation system changes in response to a flow traffic burden on the link aggregation system changing. The link aggregation system dynamically modifies the parameters in response to the changing performance of the link aggregation system. The link aggregation system is self-tuning and capable of automatically adjusting to a changing flow traffic burden on the link aggregation system.
