Abstract: A communication system includes a destination node containing a message buffer pointer input queue and a message queue memory. Moreover, the message queue memory includes message buffers. A source node of the communication system generates data packets and a message buffer pointer packet. A message network of the communication system routes the data packets and the message buffer pointer packet to the destination node. The destination node writes a data message in a message buffer of the message queue memory based on the data packets and enqueues the message buffer pointer into the message buffer pointer input queue. Further, the destination node dequeues the message buffer pointer from the message buffer pointer input queue and accesses the data message in the message buffer based on a message buffer pointer.

Abstract: An improved technique for processing IO requests has been described that distinguishes bogus IOs from genuine IO request failures by accessing a hardware configuration record that associates available paths with hardware components at different hardware layers traversed by the paths. When an IO request fails down a first path, a second path is selected for retrying the IO request by accessing the hardware configuration record and identifying a path that the record indicates traverses hardware components that are different from those traversed by the first path at multiple hardware layers. The chance that an IO request will fail due to faulty hardware over both the first path and the second path is thus low, such that IO failures down both the first path and the second path provide a clear indication that the IO request is bogus.
