Hi experts,

I have installed alps. Some test were failed. After installation I am getting following error.

[soumen@Rahman ALPS_INSTALL_PACKAGES]$ alpspython
Python 2.7 (r27:82500, May 26 2014, 22:54:42)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyalps.cthyb
>>> import pyalps.mpi
PMGR_COLLECTIVE ERROR: unitialized MPI task: Missing required environment variable: MPIRUN_RANK

Can anyone suggest where things are going wrong? Any help will be strongly appreciated.

Thanks,
