I have partially resolve my problem with the environnement variable:MPICH2_CHANNEL

but now, I have a new error message, I use the model discrete ordinate and I change the DO by scheme to accelerate the calcul.
After 3 ou 4 changing of DO --> BOOM ERROR

ex: do 1 1 1 1--->ok
do 2 2 2 2--->ok
do 3 3 3 3--->ok
do 4 4 4 4 --->ok
do 5 5 5 5 ---> error

or other example:
do 2 2 2 2 --->ok
do 4 4 4 4--->ok
do 6 6 6 6--->ok
do 8 8 8 8 --->ok
do 10 10 10 10 ---> error

example for the error message:
170 2.0357e-03 6.7638e-05 6.3893e-05 1.2912e-04 2.6070e-07 2.5162e-05 0:38:56 10
