  "message": "Adds a ParallelFor wrapper for no threads and OpenMP.\n\nWith the addition of C++11 support we can simplify the parallel for code by\nremoving the ifdef branching.  Converts coordinate_descent_minimizer.cc to use\nthe thread_id ParallelFor API.\n\nTested by building with OpenMP, C++11 threads, TBB, and no threads.  All tests\npass.\n\nAlso compared timing via the bundle adjuster.\n\n./bin/bundle_adjuster --input\u003d../problem-744-543562-pre.txt\n\nWith OpenMP num_threads\u003d8\n\nHead:\nTime (in seconds):\n  Residual only evaluation           0.807753 (5)\n  Jacobian \u0026 residual evaluation     4.489404 (6)\n  Linear solver                     41.826481 (5)\nMinimizer                           50.745857\nTotal                               73.294424\n\nCL:\nTime (in seconds):\n  Residual only evaluation           0.970483 (5)\n  Jacobian \u0026 residual evaluation     4.647438 (6)\n  Linear solver                     41.781892 (5)\nMinimizer                           50.848904\nTotal                               73.089983\n\nWith OpenMP num_threads\u003d1\n\nHEAD:\nTime (in seconds):\n  Residual only evaluation           2.990246 (5)\n  Jacobian \u0026 residual evaluation    14.132090 (6)\n  Linear solver                     79.631951 (5)\nMinimizer                          100.281847\nTotal                              122.946267\n\nCL:\nTime (in seconds):\n  Residual only evaluation           3.075178 (5)\n  Jacobian \u0026 residual evaluation    13.966451 (6)\n  Linear solver                     77.005441 (5)\nMinimizer                           97.568712\nTotal                              120.410454\n\nChange-Id: I1857d7943073be7465b6c6476bf46ab11c5475a3\n",
