+We recently discovered a new way of parallelizing a program in Java by using Parallel Java( an API and middleware for parallel programming in 100% Java on shared memory multiprocessor (SMP) parallel computers, cluster parallel computers, and hybrid SMP cluster parallel computers). 
+All the files related to this project are at [http://www.cs.rit.edu/~ark/winter2008/531/team/u8/] 
+
+We tried to simulate the test performed by them but we did not obtain the same results. The main issue that we discussed about at our presentation (the time of execution for the parallel implementation on 1 thread vs. the time of execution of the sequential algorithm) was proven to be wrong for them. As our test confirmed, the sequential algorithm runs a little bit faster.
+
+The sequential algorithm on 1 thread:
 {{{

+The parallel algorithm on 1 thread:

-We tried to integrate the parallelized algorithm into the existing framework by calling a c program from a java context.
