==Welcome==

Welcome to the Open Accelerator Infrastructure(OAI) subgroup.
OAI group is mainly working on define the common infrastructure specification for various accelerator solutions, such as common form factor, universal baseboard etc. 
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
