....to study the methodology of the design of installation routines and the behaviour of these routines in systems with di erent characteristics. The matrix is considered as divided in blocks of adjacent rows, and the blocks are assigned to the processors using a rowwise block cyclic striped mapping [5]. If the system is homogeneous the blocks can be all the same size (b) When the block size increases the imbalance increases, but the number of communications decreases. Thus, for a given matrix size (n) the installation routine must obtain the number of processors (p) and the block size, with ....

....to contention, which can be measured in the simulation. The message passing experiments implement five communication patterns, in which n processors allocated to a job communicate with each other: all to all broadcast, one to all broadcast, the n body computation, fast fourier transform (FFT) [16], and multigrid (MG) from the NAS parallel benchmarks [2] These cover many communications patterns used very frequently by highly parallel applications and provide a spectrum of message passing complexity ranging from O(n) to O(n 2 ) All to all broadcast, in which every processor in a job ....

....to solve the problem versus the size of the RRT built to solve it. For fairness of comparison, we compare the results obtained in 5000 trials run over the same motion planning problem. A way to have a numerical measure of the performance gain is to evaluate the speed up of the parallel algorithm ([13]) We compare the trend of the time spent versus the size of the tree for one, two and four processors. Such comparison however is not straightforward since the functions are not smooth. To eliminate the influence of spikes, when comparing the performances we interpolated each function with ....
