For the purposes of history on wikipedia, is anyone familiar with the origin of the phrase "embarrassingly parallel". I've always thought that it may have been coined by a random Google employee who first worked on map-reduce. Does anyone have any concrete info on the origin?

The first use I could find in an advanced Google book search was from an IEEE Computer Society digest published in 1978. The context and the fact that the author had "embarrassingly" in quotes indicates to me that the phrase was not coined here, but had been used before this.

It's decades old, but I first heard it used in reference to graphics rendering. Imagine you're rendering an animated movie: each frame is 2000x1000 pixels, there are 24 frames per second, 60 seconds in a minute, and 100 minutes in the movie. That's almost 300 billion pixels that can all be computed in parallel. That's so parallel that it's embarassing to compute it serially.
