From 6aaf62584b7da005bf22023fb3269c4f6d69fec7 Mon Sep 17 00:00:00 2001 From: Yu Feng Date: Sun, 26 Nov 2017 11:23:02 -0800 Subject: [PATCH] Mention --oversubscribe The current error message when the number of slots is insufficient (e.g. running mpirun -n 4 on a dual core machine) does not mention the use of `--oversubscribe`. In earlier version of Open MPI, the over-subscription was automatic (albeit buggy?); but the important point was no error message was printed and the application runs. Mentioning the oversubscibe flag in the message will ease up the transition to the current behaviour where explicit request is required. Also make a few other minor tweaks / cleanups to the orte-rmaps-seq:alloc-error help message.
