However, the resampling and estimation step become the bottleneck that significantly affects the speedup and scalability achieved by the parallel implementation of particle PHD filter for the requirement of joint processing of all particles.
The prolonged execution time resulting from increasing of ant population could be mitigated by the parallel implementation of the ACO.
Each tool of the toolbox provides a stylized sequential interface, and programs that use these tools may be parallelized by using the parallel implementation of the toolbox.
Besides, the overhead of the MP framework can be easily compensated by parallel implementation.
The first two cost sources can be mitigated by an efficient parallel implementation of the PSO method but the last one need the development of a robust convergence criterion for the algorithm.
The performance obtained by the proposed parallel implementation of the neXtSIM code is shown being sufficient to perform simulations for state-of-the-art sea ice forecasting and geophysical process studies over geographical domain of several millions squared kilometers like the Arctic region.
Some of these problems have been overcome by a recent parallel implementation of the MCMC method [ 6].
Due to the rapid advance of general-purpose graphics processing unit (GPU), it is an active research topic to study performance improvement of non-linear optimization with parallel implementation on GPU, as attested by the much research on parallel implementation of relatively simple optimization methods, such as the conjugate gradient method.
For this reason, in this section, we choose to present a step by step description of the parallel implementation of the 1D maximum subsequence sum and the related problems using CUDA/GPGPU.
They are based on the principle of reciprocity, another concept stressed by Prime Minister Netanyahu and embraced by us, because of our belief that parallel implementation of each side's obligation is the only way to restore the partnership between Israelis and Palestinians.
