    Abstract: Approaches presented herein provide for the reduction of workload bottlenecks during processing by offloading workload data to available data processing unit (DPU) memory, such as from graphics processing unit (GPU) memory or central processing unit (CPU) memory. Interfaces may be used to store the workload data to the pool of DPU memory, such as double data rate (DDR) memory, on-board non-volatile memory express (NVMe) devices, or NVMe devices over fabric. Interfaces may also be used to retrieve identified workload data required to complete a workload. The retrieved workload data may be provided to the GPU where the workload is completed. The pool of DPU memory may orchestrate transfers of the workload data. The workload data may be offloaded to the pool of DPU memory for training of a machine learning model. The workload data offloaded to the pool of DPU memory for training of a machine learning model may include model states, activation functions, or model checkpoints.
