solving symmetric but not hermitian matrix system

Itry to solvea linear equation system ,Ax=b,

A is complex, symmetric not hermitian, and very large matrix.

It's sizeis nearly 100000x100000.I have to distribute matrix A.

I can solve the systemwhose size is 15000x 15000 bypzgesv_ routine, so I fill the full matrix.

Is there a way to solve symmetric but not hermitian matrix sytem by one of mkl routineswithout filling the full matrix . I couldn't find any routines for my problem.the mkl's routines are generally for Hermitian positive definite system.

I would appreciate your help,

Thanks

If your matrix is sparse you could use PARDISO functionality. But could you describe what you mean when wrote about distribution of matrix A?

With best regards,
