Reducing minor garbage collection overhead

A non-transitory computer readable storage medium comprising a computer readable program for reducing garbage collection overhead, wherein the computer readable program when executed on a computer causes the computer to perform a method, the steps of the method comprising:

• specifying, by a hardware processor from a set of nodes of a Directed Acyclic Graph representing an application program, wherein each of the nodes represents a respective one of a plurality of computation tasks, any of the nodes which store a respective computation result for at least a threshold period of time as cache nodes;
• and
• allocating, by the hardware processor, the respective computation result of each of the cache nodes into a tenure area of a memory.
