Non-idempotent primitives in fault-tolerant memory
Abstract:
According to an example, a retransmission sequence involving non-idempotent primitives in a fault-tolerant memory fabric may be modified. For example, a redundancy controller may request a sequence to access a stripe in the fault-tolerant memory fabric, wherein the sequence involves a non-idempotent primitive. In response to determining an expiration of a time threshold for the non-idempotent primitive, the redundancy controller may read other data in other cachelines in the stripe, calculate a new parity value by performing an idempotent exclusive-or primitive on the new data with the other data in the stripe, and write the new parity to the stripe using an idempotent write primitive.
