Past MPI Mechanic Columns

However, MPI Mechanic has been replaced by MPI Monkey on the Cluster Monkey web site. All these old columns will be appearing there, along with new content. Woo hoo!

If you can't wait for the content to appear on Cluster Monkey, you can download PDFs of the old MPI Mechanic columns here. I ask that you do not redistribute the PDFs found on this site; they are (and will continue to be) free to download from here. Please direct anyone that wants copies of these columns to this web site: http://cw.squyres.com/. Thanks!

Columns available:

2005

• Jun 2005: Doing More With Less
Note that there are two typos in the MPI Quiz in this article (I can't edit the PDF):
1. The "MPI_ANY_SOURCE" on line 3 of "the following may be more appropriate" solution code should be "i+1".
2. The "&status" argument should be eliminated on line 4 of the "Will the following code deadlock?" section.
