Welcome to OpenCAPI Consortium

OpenCAPI Workshop – Transitioning Local Memory from DDR to the OMI Interface

Flash Memory Summit 2022 – August 1, 2022

Come visit the OpenCAPI Consortium Booth #651 at FMS 2022!

The Flash Memory Summit is live, back, and in-person and the OpenCAPI Consortium will be
there. Come early and join us Monday, August 1, 2022, for Pre-Conference Seminar D:
Transitioning Local Memory from DDR to OMI. After that, you can visit us at booth 651 where
you can learn about a new OMI development kit being prepared by OCC members TORmem,
SMART Modular, SmartDV, IBM, and AMD. During the conference don’t forget to attend the
Tuesday, August 2, 2022 panel session SARC-102-2: Open Memory Interface (OMI). We all hope
to see you there.

In this webinar, you heard about the latest on memory disaggregation research trends and applications from researchers in industry and academia.  The concept of memory disaggregation has been around for a while now. However, it only recently took-off generating wide interest.  A combination between more integrated support in CPUs (e.g., OpenCAPI coherent attachment and IBM’s POWER10 with Memory Inception) and new applications requiring unprecedented amounts of memory have made this technology an appealing solution. Applications of memory disaggregation are spanning from big-data and in memory-databases, to a tool for optimizing utilization and minimizing costs in a data-center.
