Translating Between CXL.mem and UALink Facilitating CPU Access to Remote Accelerators and GPU Fabrics

A system comprising:

• a resource provisioning unit (RPU) comprising a Compute Express Link (CXL) port configured to communicate with a first entity according to CXL.mem, and an Ultra Accelerator Link (UALink) port configured to communicate with a second entity according to a UALink-based protocol;
• wherein the RPU is configured to:
• receive, from the first entity via the CXL port, a CXL.mem Master-to-Subordinate (M2S) request;
• translate the CXL.mem M2S request to a UPLI request;
• and
• send the UPLI request to the second entity via the UALink port.

A system comprising:

• a host;
• a UALink pod comprising a UALink switch and accelerators coupled to the UALink switch,
• wherein the accelerators communicate according to a UALink-based protocol;
• a resource provisioning unit (RPU) coupled to the host via CXL.mem and coupled to the UALink switch;
• and
• wherein the RPU is configured to receive a CXL.mem Master-to-Subordinate (M2S) request from the host, translate the CXL.mem M2S request to a UPLI request, and send the UPLI request to an accelerator of the accelerators via the UALink switch.
