Server/OAI

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-Expansion)
○ 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
