Garbage collection in constrained local environments

A computing system which is configured to perform memory garbage collection based on different memory pressures, the computing system comprising:

• a digital memory;
• a processor set including at least one processor, the processor set in operable communication with the digital memory;
• a local low threshold, the local low threshold being a nonzero low memory pressure threshold of a local environment, the local environment residing in a machine of the computing system;
• a local high threshold, the local high threshold being a high memory pressure threshold of the local environment, the local high threshold greater than the local low threshold;
• a global low threshold, the global low threshold being a nonzero low memory pressure threshold of the machine;
• a global high threshold, the global high threshold being a high memory pressure threshold, the global high threshold greater than the global low threshold;
• a garbage collector control;
• and
• wherein the local low threshold, the local high threshold, the global low threshold, the global high threshold, and the garbage collector control reside in and configure the memory;
• wherein upon execution by the processor, the garbage collector control prioritizes garbage collection within the local environment as follows:
• making garbage collection within the local environment a low priority when local environment volatile memory usage is below the local high threshold and global volatile memory usage is below the global low threshold, and
• making garbage collection within the local environment a high priority when local environment volatile memory usage is above the local high threshold or global volatile memory usage is above the global high threshold or both.

A computer-readable storage device configured with data and instructions which upon execution by a processor cause a computing system to perform operations, the operations comprising:

• determining a local low threshold, the local low threshold being a nonzero low memory pressure threshold of a local environment, the local environment residing in a machine of a computing system;
• determining a local high threshold, the local high threshold being a high memory pressure threshold of the local environment, the local high threshold greater than or equal to the local low threshold;
• determining a global high threshold, the global high threshold being a high memory pressure threshold, the global high threshold greater than or equal to a global low threshold;
• and
• prioritizing garbage collection within the local environment based on the local low threshold, the local high threshold, the global high threshold, a local environment memory pressure representing volatile memory usage in the local environment, and a global memory pressure representing volatile memory usage in the machine.
