Abstract

The present invention provides a method, computer program product and system for associating one or more memory buffers with a plurality of memory channels in a computing system. The method may include associating a first memory buffer with a first plurality of memory banks, wherein the first plurality of memory banks spans a first set of one or more memory channels. Similarly, the method may include associating a second memory buffer with a second plurality of memory banks, wherein the second plurality of memory banks spans a second set of one or more memory channels. The method may also include associating a first sequence identifier and a second sequence identifier with the first memory buffer and the second memory buffer, respectively. Additionally, the method may include accessing the first memory buffer and the second memory buffer based on the first sequence identifier and the second sequence identifier.

Description

[0001] background technical field [0002] Embodiments of the invention generally relate to allocating multiple memory channels to one or more memory buffers in a computing system. Background of the invention [0003] Due to the need for increased processing speed and volume, many computer systems employ multiple client devices (eg, computing devices). In a typical computer system with multiple client devices, each client device can communicate with multiple storage devices via a system bus. The reason for the system bus inefficiency is related to the restore period of the storage device when a client device requests consecutive data transfers from the same bank of the storage device (also referred to herein as "bank contention"). A restore period refers to the delay time exhibited by a storage device between a first access to the storage device and an immediately following second access. Although the storage device accesses the data, the data is not transferred on the sys...
