A GPGPU compiler for memory optimization and parallelism management

http://portal.acm.org/citation.cfm?id=1806596.1806606

This paper presents a optimizing compiler for GPGPU. The compiler gets naive kernels, and generates the kernels that optimized in memory coalescing, thread & thread-block merging and removing memory partition camping. This paper assumes that all necessary information such as kernel index space, kernel parameters can be known at compile time. However typical CUDA or OpenCL program get the paremeter on runtime not static. Morever the benchmark that used in this paper is so trivial. The longest kernel code is just only 27 line.

TreadMarks: distributed shared memory on standard workstations and operating systems

http://portal.acm.org/citation.cfm?id=1267084

TreadMarks is a DSM system that exploits Lazy Release Consistency Model and Lazy Diff Creation. Lazy Release Consistency postpone the propgation of modifications in distributed system until the time of the acquire (later synchronization point) to reduce communication overhead. Lazy Diff Creation is a technique for false sharing, and postpone making diff to decrease the number of diffs.

In vi, do a :%s/^M//g

To get the ^M hold the control key, press V then M (Both while holding the control key) and the ^M will appear.
