Nvidia patents method to fix failed data transfers in chips
Nvidia describes a system where processing units prepare data tasks and send them to hardware. If a task fails during transmission, the system performs extra steps to ensure the operation finishes correctly.
In the filing’s own words
A system is described having one or more processing devices that prepare a work queue entry (WQE), transmit the WQE or provide a doorbell indication indicating the WQE is available, and, in response to determining an execution failure has occurred, perform at least one additional step to facilitate completion of an operation associated with the WQE.
What exactly they claim (claim 1)
1. A system comprising one or more circuits to: prepare a work queue entry (WQE); synchronize a plurality of threads of a warp; and write, by the plurality of threads of the warp, the WQE to a register.
