You can find presentations on slideshare and videos on vimeo. We will also embedded both in the agenda. The slides are also available for download as zip file.

Evaluation of X32 ABI for Virtualization and Cloud

As the Linux 3.4 has x32 ABI support, we think it's the right time for us to evaluate x32 ABI for virtualization and the cloud. The x32 ABI provides a model in x86-64 psABI with 32-bit address space, with 16 64-bit integer registers (8 additional integer registers), 8 additional SSE registers, etc., compared to the conventional x86 32-bit ABI. We look at performance improvements and memory saving gained by x32 applications, and discuss how x32 can be helpful for Xen and the clouds.
