Thanks. Openmp works. I am using linux kernel 4.3.5-300.fc23.x86_64 and Gcc 5.3.1.

One workaround for now may be to use OpenMP instead. Try configuring libMesh with "--enable-openmp". Can you tell us more about your OS/compiler?

When I do make check, the test fails at the example 'introduction_ex2', throwing out a segmentation fault error. It seems that the function EquationSystems.init() is broken, perhaps due to pthread. Unfortunately I have to use this function in my own application code. Is there anyway to fix/work around this? Thanks.
