Parallel watershed algorithm on 2D images from cranial CT-scans using PVM and MPI on a distributed machine
نویسندگان
چکیده
A parallel implementation of an image segmentation transform the watershed algorithm-is presented. The algorithm was implemented using the message passing paradigm, both with PVM and MPI and is adapted to a speciic application of determining the volume of liquor from CT-scans. The algorithm is applied on 2D images from cra-nial CT scans to extract the liquor parts from them. The evaluation on a distributed machine is included.

Benchmarking of PVM and LAM/MPI Using OSCAR, Rocks and Knoppix Clustering Tools
Parallel and distributed computing plays an important role by dividing a big process into many small processes running parallel with the help of number of processors. The communication in distributed and parallel processors takes place with the help of different API’s. In this paper the performance of two API’s i.e. PVM and LAM/MPI and three Clustering Tools OSCAR, Rocks and Knoppix is analyzed...

Algorithms for learning and optimization of Neural Networks and Genetic Algorithms often have a very high demand on computational power. Connecting distributed computers to a powerful metacomputer via a network, suucient power can be achieved. To create distributed systems, middleware tools are needed for the modelling of distributed programs, transfer of information, and control of the paralle...
متن کاملExperience with Mpi: 'converting Pvmmake to Mpimake under Lam' and 'mpi and Parallel Genetic Programming'
This looks at the issues which arose in porting the pvmmake utility from PVM to MPI. Pvmmake is a PVM application which allows a user to send les, execute commands, and receive results from a single machine on any machine in the virtual machine. Its actions are controlled by the contents of a connguration le. Its most common use is to enable management of the development of a parallel program i...
