摘要： 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.

摘要： Systems and methods for computing with multiple nodes. In some embodiments, a method includes: reading, by a first node of a plurality of nodes, from a shared memory shared by the nodes, a first data value; modifying, by the first node, the first data value; storing, by the first node, the modified first data value in a cache of the first node; initiating, by the first node, a global synchronization command; and in response to the initiating, by the first node, of the global synchronization command: indicating, by the first node, that the first node has completed a time step synchronization.
