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.

Data update of shared fabric memory in a high performance computing system

A high performance computing system including processing circuitry and a shared fabric memory is disclosed. The processing circuitry includes processors coupled to local storages. The shared fabric memory includes memory devices and is coupled to the processing circuitry. The shared fabric memory executes a first sweep of a stencil code by sequentially retrieving data stripes. Further, for each retrieved data stripe, a set of values of the retrieved data stripe are updated substantially simultaneously. For each retrieved data stripe, the updated set of values are stored in a free memory gap adjacent to the retrieved data stripe. For each retrieved data stripe, the free memory gap is advanced to an adjacent memory location. A sweep status indicator is incremented from the first sweep to a second sweep.
