Abstract: Embodiments for dynamic bandwidth allocation in cloud network switches in a cloud computing environment are provided. Quality of service (QoS) policies may be dynamically changed in one or more cloud network switches based on dynamically estimating expected traffic demands for each of a plurality of traffic classes, wherein bandwidth is dynamically allocated among queues based on changing the QoS policies.

Abstract: A computer readable storage medium for performing a transform of a multidimensional matrix in a distributed memory network by: storing a multidimensional matrix of side N in a distributed memory network with a plurality of nodes and distributing work associated with a calculation of a transform of the matrix among N2 of the plurality of nodes. The medium further receives results of the calculation of the transform of the matrix by the nodes.

Abstract: A method and system for evaluating a call to a library function at compile time. A first call included in a program being compiled by a compiler is identified. The first call is a call to a library function included in a pre-defined list of library functions external to the program. The first call includes one or more arguments associated with one or more formal arguments of a library function in the pre-defined list. The identification of the first call includes searching the pre-defined list of library functions for the library function. The arguments are determined to be constants. A second call to the library function is constructed in an optimizer of the compiler. A result of the second call is statically computed in the optimizer by issuing the second call with the constants as arguments. During compile time, the first call is replaced with the result.
