Abstract: A system and method for address translation in a multi-node computing system. In some embodiments, the system includes a first node. The first node may include: a core; and a global address translation circuit, the core including: a core processing circuit; and a memory management unit configured to map local virtual addresses to global virtual addresses, the global address translation circuit being configured to map global virtual addresses to global physical addresses.

Abstract: Provided is a method for data processing, the method including generating, by a host, a work request in a queue in a shared memory, reading, by an accelerator circuit, the work request from the queue in the shared memory, the shared memory being a physical memory that is common to the host and the accelerator circuit, and performing, by the accelerator circuit, an operation on data in the shared memory based on the work request.

Abstract: A method to address memory in nodes of a distributed memory system includes partitioning the memory in each node into one or more memory blocks available for a global memory pool. The method also includes combining, in response to a request to address memory in the global memory pool, a global bit from a global page table with a physical address to generate a global virtual address. The global bit indicates whether the memory is local or remote. The method also includes translating, using global access tuple (GAT) tables, the global virtual address to a global physical address, and addressing a memory block in the global memory pool based on the global physical address.
