- Purpose
- =======
-
- sp_ienv() is inquired to choose machine-dependent parameters for the
- local environment. See ISPEC for a description of the parameters.
-
- This version provides a set of parameters which should give good,
- but not optimal, performance on many of the currently available
- computers. Users are encouraged to modify this subroutine to set
- the tuning parameters for their particular machine using the option
- and problem size information in the arguments.
-
- Arguments
- =========
-
- ISPEC (input) int
- Specifies the parameter to be returned as the value of SP_IENV.
- = 1: the panel size w; a panel consists of w consecutive
- columns of matrix A in the process of Gaussian elimination.
- The best value depends on machine's cache characters.
- = 2: the relaxation parameter relax; if the number of
- nodes (columns) in a subtree of the elimination tree is less
- than relax, this subtree is considered as one supernode,
- regardless of their row structures.
- = 3: the maximum size for a supernode;
- = 4: the minimum row dimension for 2-D blocking to be used;
- = 5: the minimum column dimension for 2-D blocking to be used;
- = 6: the estimated fills factor for L and U, compared with A;
-
- (SP_IENV) (output) int
- >= 0: the value of the parameter specified by ISPEC
- < 0: if SP_IENV = -k, the k-th argument had an illegal value.
