This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "MPICH primary repository". The branch, master has been updated via a51b0f04291f75748f4e929ef364c2157abfb67b (commit) from dd214fe7e3e2ffeaa2a81d605e724bca026dfc61 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://git.mpich.org/mpich.git/commitdiff/a51b0f04291f75748f4e929ef364c2157… commit a51b0f04291f75748f4e929ef364c2157abfb67b Author: Rob Latham <robl(a)mcs.anl.gov> Date: Wed Aug 21 13:55:59 2013 +0000 Improve aggregation selection on Blue Gene The default "aggregators per peset" value of 8 had not been changed since Blue Gene /L. Further, allow one to set the environment variable BGMPIO_NAGG_PSET to have the same effect as setting the "bg_nodes_pset" hint. Since this is all very confusing on /Q, toss in a few more (but no doubt not enough) comments.
