How did mpi4py get installed? 

You may need to troubleshoot this with the Stampede sysadmins, since the error is being raised by the MPI library you're using.

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.
