Sequential memory access on a high performance computing system

A shared fabric memory, comprising:

• a plurality of memory devices coupled to a processing circuitry, the plurality of memory devices to:
• transmit, to the processing circuitry, first data comprising data information and parity information, comprising:
• retrieving the data information from a first portion of a first plurality of memory blocks located on a first set of the plurality of memory devices;
• retrieving the parity information from a second portion of the first plurality of memory blocks located on a second set of the plurality of memory devices;
• calculating the first data from the data information and the parity information;
• receive, from the processing circuitry, updated first data, comprising updated data information and updated parity information;
• store the updated first data in a second plurality of memory blocks in a free memory gap of the shared fabric memory;
• advance the free memory gap of the shared fabric memory to a third plurality of memory blocks adjacent to the second plurality of memory blocks.

A high performance computing (HPC) system, comprising:

• a processing circuitry comprising a plurality of processors coupled to a plurality of local storages;
• a shared fabric memory comprising a plurality of memory devices coupled to the processing circuitry to:
• execute a first sweep of a stencil code by:
• sequentially retrieving a plurality of data stripes, wherein each successively retrieved data stripe of the plurality of data stripes is adjacent to an immediately previously retrieved data stripe;
• for each retrieved data stripe, substantially simultaneously updating a set of values of the retrieved data stripe;
• for each retrieved data stripe, storing the updated set of values in a free memory gap adjacent to the retrieved data stripe;
• for each retrieved data stripe, advancing the free memory gap to an adjacent memory location;
• and
• incrementing a sweep status indicator from the first sweep to a second sweep.
