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.
