| **Note** Having multiple versions of openmpi installed is a common source of errors. During the configuration, mptopcom will display the version of openmpi it found. Please make sure that this version, and the versions of ''%%mpirun%%'', ''%%mpicc%%'', and ''%%mpicxx%%'' all agree, and ideally come from the same installation. | **Note** Having multiple versions of openmpi installed is a common source of errors.

| **Note** that this version of mptopcom contains a new algorithm for traversing the flip graph of regular triangulations, in that it checks flips for regularity rather than triangulations. The new version has been checked extensively, on the 4-cube and the 3-dilated 3-simplex and many others. Nevertheless, please let us know if you encounter any wrong results. | **Note** that this version of mptopcom contains a new algorithm for traversing the flip graph of regular triangulations, in that it checks flips for regularity rather than triangulations.
