Hi there,
Can I get some help to solve this issue?

[hzh225 at dlxlogin2-2 petsc-3.1-p4]$ make
PETSC_DIR=/home/hzh225/LIB_CFD/PETSC test
Running test examples to verify correct installation
Possible error running C/C++ src/snes/examples/tutorials/ex19 with 1 MPI
See http://www.mcs.anl.gov/petsc/petsc-as/documentation/troubleshooting.html
WARNING: It appears that your OpenFabrics subsystem is configured to only
allow registering part of your physical memory.  This can cause MPI jobs to
run with erratic performance, hang, and/or crash.

This may be caused by your OpenFabrics vendor limiting the amount of
physical memory that can be registered.  You should investigate the
relevant Linux kernel module parameters that control how much physical
memory can be registered, and increase them to allow registering all
physical memory on your machine.
