Multidimensional Scaling performance. Performance results for the three runs presented in this paper. Full MDS for the entire sample of 100,000 gene sequences required about seven hours to complete on 90 nodes (720 cores) of Polar Grid Quarry at Indiana University. Interpolation with equal in-sample and out-of-sample sizes (50,000 sequences each) required about three and half hours to complete. Interpolation with 10,000 in-sample sequences and 90,000 out-of-sample sequences required less than an hour to complete.
