The Cell BE processor is a heterogeneous multicore that contains one PowerPC Processor Element (PPE) and eight Synergistic Processor Elements (SPEs). Each SPE has a small software-managed local store. Applications must explicitly control all DMA transfers of code and data between the SPE local stores and the main memory, and they must perform any coherence actions required for data transferred. The...
Recently, Intel has introduced a research prototype many core processor called the Single-chip Cloud Computer (SCC). The SCC is an experimental processor created by Intel Labs. It contains 48 cores in a single chip and each core has its own L1 and L2 caches without any hardware support for cache coherence. It allows maximum 64GB size of external memory that can be accessed by all cores and each core...
In this paper, we propose a software shared virtual memory (SVM) system for heterogeneous multicore accelerator clusters with explicitly managed memory hierarchies. The target cluster consists of a single manager node and many compute nodes. The manager node contains a generalpurpose processor and larger main memory, and each compute node contains a heterogeneous multicore processor and smaller main...
