Focused crawls are collections of frequently-updated webcrawl data from narrow (as opposed to broad or wide) web crawls, often focused on a single domain or subdomain.
Game of life: An implementation of the famous simulation game with parallel programming technologies. An MPI, a hybrid MPI and OpenMp and a CUDA implementation of the game. Also I wrote a report in greek on the speedup, efficiency and scalability of each implementation.
In this task, we had to write a multi-threaded MPICH program, that will solve the consensus problem. If all the slave (child) processes agree on a single decision, then the processes will terminate displaying consensus reached.
In this task, I wrote the code using both OpenMP and MPI inorder to parallelize it. What it does is that the master process distributes a chunk of number equally among the slave processes. Each slave process then searches for the number to find. When one slave process finds the number, it sends a message to the master process who then sends a "terminating message" to the slave processes who then abort their search.
