TECHNOLOGIES FOR SCALABLE REMOTELY ACCESSIBLE MEMORY SEGMENTS

Technologies for one-side remote memory access communication include multiple computing nodes in communication over a network. A receiver computing node receives a message from a sender node and extracts a segment identifier from the message. The receiver computing node determines, based on the segment identifier, a segment start address associated with a partitioned global address space (PGAS) segment of its local memory. The receiver computing node may index a segment table stored in the local memory or in a host fabric interface. The receiver computing node determines a local destination address within the PGAS segment based on the segment start address and an offset included in the message. The receiver computing node performs a remote memory access operation at the local destination address. The receiver computing node may perform those operations in hardware by the host fabric interface of the receiver computing node. Other embodiments are described and claimed.
