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 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: A computing node in a multi-node computing system includes a local memory, at least one processor, and an access library. The at least one processor runs an operating system that runs a distributed application in a virtual address space. The application includes a process that generates a first memory access request that includes a first virtual address. The access library is responsive to the first memory access request by: converting the first virtual address into a first physical address, accessing the local memory based on the first physical address including a first indication that the first memory access request is for the local memory, and accessing a global access tuple table based on the first physical address including a second indication that the first memory access request is for memory located on a second computing node of the multi-node computing system that is remotely located from the computing node.

Abstract: Systems and methods for computing with multiple nodes. In some embodiments, the method includes: determining that a first data value in a cache is a global data value; setting a first flag to indicate that the first data value is a global data value; and selectively invalidating one or more portions of the cache, wherein the selective invalidating of the cache includes: determining, based on the first flag, that the first data value is a global data value; and based on the determining, invalidating the first data value.

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.
