Parallel computer system, controlling method for parallel computer system, and storage medium storing controlling program for management apparatus

摘要

A node state storage unit stores therein information about a free state of each of the computation nodes. A search data storage unit has a data structure in which a state where the X-axis is crossed is developed into a virtual X-axis provided on the right end of the X-axis. By referring to the node state storage unit, a searching unit searches for the number of successive free nodes in the increasing directions of the X-axis including the virtual X-axis and the Y-axis, while using the computation node at each of the X-Y coordinate positions as a starting point, and writes a search result into the search data storage unit.

主权项

1. A parallel computer system comprising: a parallel computer including a predetermined number of information processing apparatuses that are connected together in a toric form via connection ends in a direction of a predetermined axis; and a management apparatus that manages the parallel computer, wherein
the management apparatus includes:
a search data storage unit that stores therein, for each of the information processing apparatuses used as a starting point, search data about a successive-free-apparatus number indicating how many information processing apparatuses are found in a search to be successively in a free state with respect to each of directions of all axes from the starting-point information processing apparatus, the search being conducted in twice as many information processing apparatuses as the predetermined number by crossing the connection ends positioned in the direction of the predetermined axis;a searching unit that, by using the search data stored in the search data storage unit, searches for the successive-free-apparatus number while including situations where the connection ends are crossed in the direction of the predetermined axis; andan allocating unit that allocates two or more of the information processing apparatuses to an allocation target job, on a basis of the successive-free-apparatus number found in the search by the searching unit.
