I am Mehdi and this is my first time using this forum.
I need to used cluster_sparse_solver in my FORTRAN Finite Element program. Because the degree of freedom of my system is very high (1^6), the number of nonzero members in the stiffness matrix (A in Ax=B) will be also very high in a way that I can not store the number of non-zero in an integer number with type 4 and I must use integer(8). Therefore, the parameter ia (row indexing of sparse matrix) must be integer(8).
In this situation, how I should compile my program. I have tried to use 4 bit and 8 bit libraries, during compiling of my program and none of them are working. Shall I use all of the integers in my program with type integer(8)? When ia in integer(8) and ja is integer(4), is it possible to compile the program?
Please help me. I can provide any more information you may need.
