Abstract
A deterministic hardware indictment process is used to indict one Compute Node (CN) of a pair of CNs in response to occurrence of a fatal error on a Peripheral Component Interconnect Express (PCIe) Non-Transparent Bridge (NTB) interconnecting the two CN. Status information is exchanged between the CNs on a communication medium that is separate from the NTB. The indictment process is run locally on each CN based on whatever information is available to the CN. When the CN does not receive status information from the other CN, the CN runs a self-indictment check. When status information is received, and only one CN reports an error, the indictment process indicts the compute node that reported the error. If both CNs report errors, an error severity comparison process is used to select a CN to be indicted. If the reported errors are equally severe, a default CN is indicted.
