==Welcome==

Welcome to the Open Accelerator Infrastructure subgroup under OCP Server Work Group.
The scope of this OAI subgroup is to define below 9 schedules for physical modules include logical aspects such as electrical, mechanical, thermal, management, hardware security, physical serviceability, etc. to produce solutions compatible with existing/traditional operation systems and frameworks to run heterogeneous accelerator applications.
 ○ Open Accelerator Infrastructure (OAI)
 ○ OCP Accelerator Module (OAI-OAM)
 ○ OAI Universal Baseboard (OAI-UBB) 
 ○ OAI Host Interface (OAI-HIB)
 ○ OAI Power Distribution (OAI-PDB)
 ○ OAI Expansion Beyond UBB (OAI-EXP)
 ○ OAI Security, Control, and Management (OAI-SCM) 
 ○ OAI-Tray
 ○ OAI Chassis (This chapter will address air-cooled and liquid-cooled aspects as well.)

There are 5 workstreams under this group working on above schedules:

 ○ OAI System workstream
 ○ Highspeed workstream
 ○ Power workstream
 ○ Thermal and Cooling workstream
 ○ OAMTool workstream
