Hi, I updated our OpenMPI install from 1.8.3 to 1.8.8 today and I'm getting this error:
XRC error: bad XRC API (require XRC from OFED pre 3.12). This happens even using the exact same node to compile and run an example program. I saw a thread from a few weeks ago discussing this issue as well. I changed the dlsym if statement in btl_openib_xrc.c to this: if (NULL != dlsym(lib, "ibv_create_xrc_recv_qp@@IBVERBS_1.1")) { This seems to make the error message go away, so there must be something about that check that doesn't work right without the version in it. This is on a Scientific Linux 6.6 machine with MLNX_OFED 1.5.3-4.0.42. Andy -- andy wettstein hpc system administrator research computing center university of chicago 773.702.1104
