  • Memory switching protocol when switching optically-connected memory
    Patent number: 9390047
    Abstract: Data is collected by an active node from passive nodes. A source node extracts the data format, and a remote memory blade identification (ID), a remote memory blade address, and ranges of the RMMA space, and composes and sends metadata to receiving nodes and receiving racks.
    Type: Grant
    Filed: February 3, 2016
    Date of Patent: July 12, 2016
    Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
    Inventors: Eugen Schenfeld, Abhirup Chakraborty

  • Memory switching protocol when switching optically-connected memory
    Patent number: 9110818
    Abstract: Data is collected by an active node from passive nodes and arranges and stores the collected data on receiving nodes. A source node extracts the data format, and a remote memory blade identification (ID), a remote memory blade address, and ranges of the RMMA space, and composes and sends metadata to the receiving nodes and receiving racks. The RMMA space is unmapped by the source node thereby removing all entries in page tables that map a linear address to a remote RMMA space. The system memory address (SMA) space that is associated with alternative RMMA space is free.

  • Address space management while switching optically-connected memory
    Patent number: 9104586
    Abstract: A remote processor is signaled for receiving a remote machine memory address (RMMA) space that contains data to be transferred. The RMMA space is mapped to a free portion of a system memory address (SMA) space of the remote processor. The entries of a page table corresponding to the address space are created.

  • Remote memory management when switching optically-connected memory
    Patent number: 9104587
    Abstract: A remote memory superpage is retained in a remote memory of the memory blade when reading the remote memory super page of the remote memory into a local memory.

  • Address space management while switching optically-connected memory
    Patent number: 8954701
    Abstract: Memory is dynamically switched through the optical-switching fabric using at least one communication pattern to transfer memory space in the memory blades from one processor to an alternative processor in the processor blades without physically copying data in the memory to the processors. Various communication patterns for the dynamically switching are supported.
