几乎所有关于“商品”与“自定义”体系结构的讨论，尤其是对于高度平行的系统，都集中在高层，高复杂的处理器核心上。本文采用了不同的解决方案 - 它通过对经典的“愚蠢”内存接口进行编程，探讨了直接攻击内存墙的潜力。涉及几种相关但可分开的技术：将构成内存请求的数据转换为“行程线程”的机器状态，并开发一个可以通过极短的说明来操纵此状态的ISA，该说明允许将完整的程序存储在访问数据包。结果很有趣：存在广泛的功能应用程序，该方法可为带宽和潜伏期提供显着改善
Virtually all of the discussion on "commodity" vs. "custom" architectures, especially for highly parallel systems, has focused on the high-glamor, high complexity processor core. This paper takes a different tack - it explores the potential for directly attacking the memory wall by programming the classically "dumb" memory interface. Several related but separable techniques are involved: converting the data that makes up a memory request into the machine state of a "traveling thread", and developing an ISA that can manipulate this state via extremely short instructions that allow complete programs to be stored within the access packet. The results are interesting: a wide spectrum of functions applications exist for which this approach provides significant improvement in bandwidth and latency
