My apologies for the tardy response - been stuck in meetings. I'm glad to hear that you are making progress tracking this down. FWIW: the error message you received indicates that the socket from that node unexpectedly reset during execution of the application. So it sounds like there is something flaky in the Ethernet.
One thing I've found that can cause that problem is two nodes having the same IP address. This causes periodic random resets of the connections. So you might want to just do an IP scan to ensure that all the addresses are unique. Let us know if we can be of help Ralph On Tue, Apr 12, 2016 at 7:22 AM, Stefan Friedel < stefan.frie...@iwr.uni-heidelberg.de> wrote: > On Tue, Apr 12, 2016 at 01:30:37PM +0200, Stefan Friedel wrote: > >> -thanks for you support!- nope, no core, just the "orte has lost"... >> > Dear list - the problem is _not_ related to openmpi.
