I have two questions about DSS solver.
1. Why is the first use of dss_reorder( ) VERY SLOW? For a matrix 1300x1300 with only 5000nnz I had to stop my program because it hunged (even for a matrix of size 7 it takes about a second or two to reorder) Is this normal, or I am doing some kind of a mistake....
2. What could possibly be a couse of an error "MKL-DSS-DSS-Error, An unclassifiable error occured"? I get it while using several time the routine for solving which is almost identical to an example program in dss_sym. It always crashes on reordering routine and it occures in unpredictable moments. This happens during solving the same system in each routine call.
Thank you in advance for any answer
