3D geometric reconstruction from digital images captured from consumer cameras is an inexpensive, but computationally demanding application. In this experimental study, the authors have explored parallelism in the best known public domain software (Bundler and PMVS2) and found that massive parallelism exists at various levels that can be exploited on various computer architectures (Such as multi-cores, distributed memory and GPU machines). Although in this report, they present results for multi-core and distributed memory machines, but they believe that similar results could be obtained on vector machines and GPU architectures as well. They have tested the MPI codes on a large clusters of 500 Linux nodes.
