The MPS-datafiles are in plato.asu.edu/ftp/miqp/ and the AMPL files in plato.asu.edu/ftp/ampl_files/miqp_ampl/

The following codes were run in default mode on a 2.66GHz Intel Core2 Quad, For accuracy reached, see logfiles. In the last columns are results for the QCQPs obtained by rewriting the QPs as: min t, subject to quadratic obj <= t plus constraints. SCIP and MOSEK do transformations. SCIP uses relgap=0;
