Method and system for using a distributable virtual address space

A method for using a distributable virtual address space comprising:

• receiving a message including a request for mapping a virtual address to a first physical memory location of a first network node of a plurality of network nodes, wherein the first physical memory location is accessible by a first processor of the first network node when processing a first machine code instruction including the virtual address as an operand of the machine code instruction;
• determining node identification information indicating a second network node of the plurality of network nodes hosting a second physical memory location mapped to the virtual address;
• and
• transmitting a message including mapping information to at least one of the first network node and the second network node, allowing remapping of the virtual address from the second physical memory location of the second network node to the first physical memory location of the first network node.

A system for using a distributable virtual address space comprising:

• a first network node of a plurality of network nodes using a distributable virtual address space, the first network node including:
• a first physical memory location mapped to a virtual address in the distributable virtual address space;
• a first processor of the first network node having access to the first physical memory location using the virtual address when processing a first machine code instruction including the virtual address as an operand of the first machine code instruction on the first network node;
• and
• a second network node of the plurality of network nodes sharing the distributable virtual address space, the second network node comprising:
• a second physical memory location capable of being mapped to the virtual address in the distributable virtual address space;
• a second processor of the second network node having access to the second physical memory location;
• a distributable memory manager (DMM) configured to remap the virtual address to the second physical memory location, wherein the second processor can access the second physical memory location using the virtual address when processing a second machine code instruction including the virtual address as an operand of the second machine code instruction on the second network node.

A computer program product embodied in a computer-readable storage medium for using a distributable virtual address space, the computer program product comprising instruction for, when executed by a processor:

• receiving a message including a request for mapping a virtual address to a first physical memory location of a first network node of a plurality of network nodes, wherein the first physical memory location is accessible by a first processor of the first network node when processing a first machine code instruction including the virtual address as an operand of the machine code instruction;
• determining node identification information indicating a second network node of the plurality of network nodes hosting a second physical memory location mapped to the virtual address;
• and
• transmitting a message including mapping information to at least one of the first network node and the second network node, allowing remapping of the virtual address from the second physical memory location of the second network node to the first physical memory location of the first network node.
