While trying to send a message of size 1610612736 B (1.5 GB), I get the following error:
[[52363,1],1][../../../../../../ompi/mca/btl/openib/btl_openib_component.c:2951:handle_wc] from grsacc20 to: grsacc19 error polling LP CQ with status LOCAL LENGTH ERROR status number 1 for wr_id 18729360 opcode 128 vendor error 105 qp_idx 3
Reducing the size to 1 GB works fine. I assume that this is rather related to Infiniband itself than to Open MPI.
I'm using Open MPI 1.4.1.
Any ideas on that?
Thank you very much.
