Figure 8.

Running time of layout-mst as a function of the number of processors. The running time for six different data sets from NCBI GEO are shown after averaging across 5 trials. The system used is a 2.4 GHz Intel Core 2 Quad CPU (Q6600) with 8 GB RAM and the number of virtual processors range from 1 to 8. The files generated were Portable Network Graphics files (PNG) at a resolution of 300 dots per inch (DPI). (Higher resolutions require more time.)
