Abstract: An information processing system includes: a management apparatus coupled to nodes to execute data transfer, wherein the management apparatus preforms operations to: acquire data transfer information in which a priority level of data transfer and an identifier of a node that executes the data transfer are associated with an identifier of the data transfer; identify, when receiving an execution instruction of first data transfer, one or more first nodes that execute second data transfer having a lower priority level than a priority level included in information of the first data transfer based on the data transfer information; and transmit, to each of the one or more first nodes, a stop request to stop the second data transfer, and a transfer request including the information of the first data transfer and information of a portion to be executed by the first node of the first data transfer by the first node.

Abstract: An ultra high strength fiber-reinforced cement composition includes cement, silica fume, coal gasification fly ash, insoluble anhydrous gypsum, and metal fiber having a length between 5 and 30 mm and a diameter of between 0.1 and 1 mm. The coal gasification fly ash is spherical fine particles having a maximum particle size between 5 and 10 ?m. Mass ratio of the silica fume: the coal gasification fly ash is 95 through 50 portions: 5 through 50 portions.

Abstract: Therefore, the problem to be solved by the present invention is to provide highly general purpose ultra high strength fiber-reinforced mortar or concrete that shows a higher fluidity (workability) at the fresh state, a higher bending strength with a less content of metal fiber by enhancing both the absolute value of the compressive strength of mortar -matrix excluding metal fiber and the ratio of the bending strength relative to the compressive strength simultaneously at the hardened state, and acceptability of fine aggregate being used in ordinary ready-mixed concrete. An ultra high strength fiber-reinforced cement composition is characterized in that it contains cement, silica fume, coal gasification fly ash, gypsum and metal fiber and that the mass ratio of silica fume : coal gasification fly ash is 95 through 50 portions: 5 through 50 portions. Ultra high strength fiber-reinforced mortar or concrete contains such a cement composition and fine aggregate.
