Abstract: A computer-implemented method for collecting diagnostic data within a multiprocessor system that includes capturing diagnostic data via a plurality of collection points disposed at a source location within the multiprocessor system, routing the captured diagnostic data to a data collection station at the source location, providing a plurality of buffers within the data collection station, and temporarily storing the captured diagnostic data on at least one of the plurality of buffers, and transferring the captured diagnostic data to a target storage location on a same chip as the source location or another storage location on a same node.

Abstract: A method of managing a temporary memory includes: receiving a request to transfer data from a source location to a destination location, the data transfer request associated with an operation to be performed, the operation selected from an input into an intermediate temporary memory and an output; checking a two-state indicator associated with the temporary memory, the two-state indicator having a first state indicating that an immediately preceding operation on the temporary memory was an input to the temporary memory and a second state indicating that the immediately preceding operation was an output from the temporary memory; and performing the operation responsive to one of: the operation being an input operation and the two-state indicator being in the second state, indicating that the immediately preceding operation was an output; and the operation being an output operation and the two-state indicator being in the first state, indicating that the immediately preceding operation was an input.
