Dear Nathan and all, Thank you for your information. I tried it in this morning, it seems to get the same result. I will try another option. Thank you for the key to go in. And I found a statement in the FAQ ragarding PETSc which says you should use OpenMPI wrapper compiler. I use wxWidgets library and try to compile with the wrapper. 2015/10/27 23:56、Nathan Hjelm <hje...@lanl.gov> のメール：
