Guys, I've been doing some testing with the some of the standard benchmarks cases. H2O-1024, 2048, 4096, etc. H20-1024 runs with the distributed and replicated. H2O-2048 runs only with the replicated. Can someone else try to run the H20-2048 with the distributed data algorithm to see if they get that same error? It happens right after initial guess, before the OT starts. * *** ERROR in pack_matrix almost there *** * *** Matrix block not found *** <div class="gmail_quote">On Fri, Feb 29, 2008 at 5:31 PM, Matt W <<a href="mailto:MattWa...@gmail.com">MattWa...@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Engaging brain a bit harder (it is Friday night here) a possible cause is an overflow in the routine pair2int (realspace_task_selection, line 72)...but I hope not.
