Abstract: A high performance computing system that includes a shared fabric memory and a plurality of processors is disclosed. A first processor is coupled to a local storage and executes a first process that, in combination with other processes, causes the plurality of processors to perform certain actions including transferring, from the shared fabric memory to the local storage, a first value corresponding to a first cell of a first set of cells and a first sweep of a stencil code. The actions further include transferring, from a first logical partition in the shared fabric memory associated with the first cell to the local storage, a second value corresponding to a second cell related to the first cell and not in the first set of cells. Further, these actions include updating, by the first process, the first value based on at least the first value and the second value.

Abstract: Systems and methods associated with page modification are disclosed. One example method may be embodied on a non-transitory computer-readable medium storing computer-executable instructions. The instructions, when executed by a computer, may cause the computer to fetch a page to a buffer pool in a memory. The page may be fetched from at least one of a log and a backup using single page recovery. The instructions may also cause the computer to store a modification of the page to the log. The modification may be stored to the log as a log entry. The instructions may also cause the computer to evict the page from memory when the page is replaced in the buffer pool. Page writes associated with the eviction may be elided.

Abstract: A memory region has logical partitions. Each logical partition has data packages. The memory region discontiguously stores the data packages of the logical partitions. A writing process can discontiguously generate the data packages of the logical partitions. A reading process can contiguously retrieve the data packages of a selected logical partition.
