This doesn’t look like an error with multiple initializations. If you do that MPICH will throw an error saying "Cannot call MPI_INIT or MPI_INIT_THREAD more than once”. It looks like you might not be using SLEPc correctly. Perhaps ask for help on their mailing list? — Pavan On May 16, 2014, at 6:56 PM, 张国熙 <[email protected]> wrote:

Hi, all

I'm using SLEPc as an eigensolver, which implemented MPICH for multiprocess usage.

I compile SLEPc code into a .so library B.

My executable program A calls .so library B, and .so libraryB calls SLEPclibrary. I used to put MPI_Init() only in A. But it will got stuck. Then I try to put it in A,B( and C,SLEPc init will call this function).

I think it is because I called MPI_Init for more than one times. Because if I only call it in A, and C(SLEPc call), code in A,B will be executed, but stuck at C. If I call it in A,B,C. Code in A will be executed, and stop at B.

I think even if I call MPI_Init for more than one times, it should return to me something like "MPI_Init has been called". Do anyone know how to fix it?Thanks.
