spec: Each processor owns a range of subboxes in each of the three dimensions , i.e ., the processors are logically arranged into a three-dimensional grid . Initially , each processor generates this list for subbox pairs in which local subboxes and nonlocal subboxes in half of the directions are involved , i.e ., north , but not south , etc. Pairs of subboxes on the same processor are always handled by that processor . Note that in this figure each processor owns four subboxes , and that the cutoff radius extends two subboxes . That is , for optimum efficiency you are forced to depart from the traditional von Neumann uniprocessor architecture , and instead use a parallel , multiprocessing architecture , where each processor is associated with some local memory . It 's not just because envelopes have defined edges just begging to be pushed . The subbox pair list on each processor is ordered such that atomic coordinates from a remote subbox are retrieved only once per molecular dynamics step . Jonathan will welcome fellow guest speakers Simon Parker , Professor of Entrepreneurship with the Barclays Centre for Entrepreneurship based at Durham Business School , the University of Durham , and Ted Fuller , Professor of Entrepreneurship and Strategic Foresight at Teesside Business School , the University of Teesside . The deepest level cells are assigned to processors such that each processor has contiguous cells and static load balancing is achieved by redistributing the cells so that each processor has approximately same number of atoms . Each processor is small enough where adding multiple chips does n't increase the size of the phone 's motherboard dramatically , he said . In this way , each processor owns a subgrid of subboxes . SWITZERLAND : Switzerland is a federal country with powerful cantons . At every step in the calculation , each processor needs to know what the results are in the neighboring volumes before calculating the next step . He was then under the hopeful impressions of the '' Wittenberg Concordia , `` which Bucer had brought about by his elastic diplomacy , May , 1536 , but which proved , after all , a hollow peace , and could not be honestly signed by the Swiss . What they share , consistently and persistently , is the fantasy of cutting the Gordean Knot . The lamp flickers and goes out for a minute ; when it again flashes on , the Angel and the Professor 's Son are seen standing in the room , as though they had come there directly from the close of the preceding act ; the Angel , however , has completely removed all Y.M.C.A . One method of doing so is to have a partitioned secondary storage in which each processor owns a logical disk . If Tony Blair wants another fight with the green lobby , this is the way to do it `` . The number of graduate students provided with assistantships rose again in 1996 with a total of 21 being supported . He did so because he believed that , unless partnerships were to be created , the largely black school children would be forgotten by the largely white regional institutions . These excerpts support the above explanation by the Ambassador regarding the purpose of his visit to Niger and do not contain any references to discussions about uranium supply from Niger . Second , mental health services were utilized by 81,437 clients in 609,314 visits . There are many texts available on explosive devices so I will leave it to you to seek out and learn from these sources . In the second class of parallelization approaches , the physical space in the molecular system is distributed instead of the atom list.8-13 In this scheme , each processor is responsible for the calculation of forces of the atoms that occupy the region or domain assigned to the processor . Based on the cutoff radius and the size of the subboxes , each processor generates a pair list of subboxes for which interactions need to be evaluated .
