Parameter options for ILUT, ParaSails and polynomial preconditioners are defined
Parameter options for ILUT, ParaSails and polynomial preconditioners are defined.
- euclidNlevels xxx
- where xxx is an non-negative integer specifying the desired sparsity of the incomplete factors. The default value is 0.
- euclidThreshold xxx
- where xxx is a floating point number specifying the threshold used to sparsify the incomplete factors. The default value is 0.0.
- parasailsThreshold xxx
- where xxx is a floating point number between 0 and 1 specifying the threshold used to prune small entries in setting up the sparse approximate inverse. The default value is 0.0.
- parasailsNlevels xxx
- where xxx is an integer larger than 0 specifying the desired sparsity of the approximate inverse. The default value is 1.
- parasailsFilter xxx
- where xxx is a floating point number between 0 and 1 specifying the threshold used to prune small entries in
. The default value is 0.0.
- parasailsLoadbal xxx
- where xxx is a floating point number between 0 and 1 specifying how load balancing has to be done (Edmond, explain please). The default value is 0.0.
- parasailsSymmetric
- sets Parasails to take
as symmetric.
- parasailsUnSymmetric
- sets Parasails to take
as nonsymmetric (default).
- parasailsReuse
- sets Parasails to reuse the sparsity pattern of
.
- polyorder xxx
- where xxx is the order of the least-squares polynomial preconditioner.
