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.
