[yt-users] Problem in running parallel yt on stampede

Dear yt-users, I'm trying to use parallel yt on stampede and got this error -- LiMIC: (limic_open) file open fail [unset]: aborting job: Fatal error in PMPI_Init_thread: Other MPI error, error stack: MPIR_Init_thread(436)....: MPID_Init(371)...........: channel initialization failed MPIDI_CH3_Init(335)......: MPIDI_CH3I_SMP_Init(1723): LiMIC2 device does not exist: No such file or directory In the interactive ipython, import yt and import mpi4py works ok but, yt.enable_parallelism() gives the same error. Serial scripts runs perfectly fine. I've also tried building mpi4py by specifying mpicc path; itdoesn't work. Any help would be highly appreciated. Thanks in advance. rahul
