多态并行处理器中的线程管理器设计

基于多态并行处理器提出了一种硬件线程管理器,支持MIMD模式8个线程管理操作和SIMD模式SC控制器统一管理两种工作模式,实现了线程级并行计算;可以监测各个线程的工作情况以及近邻通信寄存器和路由器的状态;能够在通信时停止、切换、启动线程,记录每个线程的工作状态,同时避免了因数据阻塞带来的等待问题,能够最大程度地提高单个处理器的执行效率....

Summary:基于多态并行处理器提出了一种硬件线程管理器,支持MIMD模式8个线程管理操作和SIMD模式SC控制器统一管理两种工作模式,实现了线程级并行计算;可以监测各个线程的工作情况以及近邻通信寄存器和路由器的状态;能够在通信时停止、切换、启动线程,记录每个线程的工作状态,同时避免了因数据阻塞带来的等待问题,能够最大程度地提高单个处理器的执行效率.
Bibliography:This paper proposes a hardware thread manager for the polymorphic parallel processor. The thread manager supports the MIMD mode with 8 threads and SIMD mode with multiple threads using the SC controllers in an unified approach to manage two operating modes to achieve a thread-level parallelism. Thread manager can monitor each thread＇s work, neighboring communication register and router status. It can stop, switch and start threads. Thread manager can also record the working status of each thread, while avoiding the waiting problem caused by data congestion. This manager is able to maximize the efficiency of a single processor.
