Similar to previous versions of the standard, the MPI-3.1 standard is now available in hardcover.

Even though I have a copy of the MPI-3.1 PDF for quick/easy reference on my laptop, I find something intangibly inherently useful (and comforting?) in having a paper copy of the standard to thumb through.

The books have been (literally) spanning the color spectrum:

• MPI 2.1: hardcover was yellow
• MPI 2.2: hardcover was orange
• MPI 3.0: hardcover was green
• MPI 3.1: hardcover is blue

The books are available at cost - yes, that's right: this is not a profit-generating endeavor - by the good people at HLRS (specifically, through the efforts of Dr. Rolf Rabenseifner and his team).

The MPI-3.1 blue book is 38oz of parallel computing goodness.
