unconditionally, which can result in a flood of messages to the user if all MPI processes invoke abort. Additionally, some users were confused because they saw the MPI_ABORT opal_output() messages from ''some'' MPI processes, but not ''all'' of them (despite the fact that every MPI process supposedly invoked MPI_ABORT). The reason is that calling MPI_ABORT triggers ORTE to kill all MPI processes, so it's a race condition as to whether a) all MPI processes actually invoke MPI_ABORT, and/or b) whether every process is able to opal_output() before they are killed. This commit does two simple things: * Now use orte_show_help() for the MPI_ABORT message, so they are aggregated. * Add a note in the message that calling MPI_ABORT kills all processes, so you might not see all output, yadda yadda yadda. This commit was SVN r19735.
