GPU ASSISTED GARBAGE COLLECTION |
摘要 |
A system and method for efficient garbage collection. A general-purpose central processing unit (CPU) sends a garbage collection request and a first log to a special processing unit (SPU). The first log includes an address and a data size of each allocated data object stored in a heap in memory corresponding to the CPU. The SPU has a single instruction multiple data (SIMD) parallel architecture and may be a graphics processing unit (GPU). The SPU efficiently performs operations of a garbage collection algorithm due to its architecture on a local representation of the data objects stored in the memory. The SPU records a list of changes it performs to remove dead data objects and compact live data objects. This list is subsequently sent to the CPU, which performs the included operations.
