Abstract
Embodiments of the present disclosure relate to a method, a device, and a computer program product for data access. The method includes acquiring a priority of a workload associated with an input/output (I/O) instruction of a user, and determining, based on the priority, whether to perform data access to a persistent memory indicated by the I/O instruction by using a central processing unit (CPU). If it is determined not to perform the data access by using the CPU, the data access is performed by using a programmable data moving apparatus. The method according to the embodiments of the present disclosure can avoid that important workloads compete for CPU resources equally with secondary workloads, and alleviate blocking of workloads due to insufficient CPU resources, thereby improving the overall performance of persistent memory access.
