Sun’s Ruud van der Pas debunks some of the myths about OpenMP parallel programming:

"As suggested by the name, memory consistency defines what memory state the various threads of execution observe. They need not have the same view at a specific point in time. The problem with this is that at certain points in a shared memory parallel program, the developer may want to enforce a consistent view to ensure that modifications made to shared data are visible to all threads, not only the thread(s) that modified this data. This has however nothing to do with OpenMP.

About Rich
FlexRex began his life as a cartoon character I created a Sun Microsystems. As the world's first "fictional blogger," he appeared in numerous parody films that made fun of the whole work-from-home thing. Somewhere along the line, the Sun IT department adopted FlexRex as their spokesman in a half-dozen security awareness films for employees. So when I left Sun recently, I started FlexRex Communications, a Marketing company in Portland, Oregon.
