[PATCH 0/5] Live Migration Acceleration with IAA Compression

[Yuan Liu <yuan1.liu@intel.com>]

Hi,

I am writing to submit a code change aimed at enhancing live migration
acceleration by leveraging the compression capability of the Intel
In-Memory Analytics Accelerator (IAA).

Enabling compression functionality during the live migration process can
enhance performance, thereby reducing downtime and network bandwidth
requirements. However, this improvement comes at the cost of additional
CPU resources, posing a challenge for cloud service providers in terms of
resource allocation. To address this challenge, I have focused on offloading
the compression overhead to the IAA hardware, resulting in performance gains.

The implementation of the IAA (de)compression code is based on Intel Query
Processing Library (QPL), an open-source software project designed for
IAA high-level software programming.

Best regards,
Yuan Liu
