GPU Method and Apparatus forhierarchical RAID with erasure coding accelerating based onvirtual GPU

摘要

Disclosed are a method and an apparatus for a hierarchical RAID applied with erasure code acceleration in a virtualization GPU environment. The method for a hierarchical RAID applied with erasure code acceleration in a virtualization GPU environment of the present invention comprises the steps of: allowing a master virtual machine to divide input data into data chunks; generating an external parity disk in a host from the input data; allowing a GPU kernel to calculate external parity data to transfer the same to a CPU memory; allowing the master virtual machine to store the external parity disk and the external parity data in an external parity node; generating an internal parity disk in an internal data node; allowing a slave virtual machine to calculate internal parity data to transfer the same to a GPU memory from the CPU memory; allowing the GPU kernel to call a multi-GPU thread in order to generate internal parity data in parallel; and allowing the slave virtual machine to store the internal parity data and the internal parity disk in the internal data node.
