Allocating Heaps in NUMA Systems
First Claim
Patent Images
1. A method comprising:
- operating a computer system comprising a plurality of processor groups and a plurality of memory banks, each of said processor groups having a corresponding one of said memory banks;
while operating said computer system, receiving a first process comprising instructions that operate on a first memory object;
selecting a first processor being contained in a first processor group, said first processor group corresponding to a first memory bank;
allocating first heap memory to said first process from said first memory bank; and
executing said first process on said first processor using said first heap memory.

Abstract
Processes may be assigned heap memory within locally accessible memory banks in a multiple processor NUMA architecture system. A process scheduler may deploy a process on a specific processor and may assign the process heap memory from a memory bank associated with the selected processor. The process may be a functional process that may not change state of other memory objects, other than the input or output memory objects defined in the functional process.
