AI Technical Summary
Existing distributed schedulers face performance-inhibiting imbalances between pickable scheduler queues and execution pipes due to uneven distribution of instruction operations, leading to underutilized execution pipes and reduced execution performance.
A multimodal distributed scheduler with a non-pickable scheduler queue and multiple pickable scheduler queues, employing queue-first, pipe-first, and speculative allocation modes to dynamically balance queue and execution pipe occupancies by interleaving and speculative allocation of instruction operations based on occupancy thresholds and pick rates.
The scheduler effectively mitigates queue and pipe imbalances, enhancing execution performance by optimizing the distribution of instruction operations and utilizing execution resources more efficiently.
