摘要： Identifying computer system markers to understand computer system performance, in one aspect, may comprise identifying a set of executions of applications indicative of computer performance based on first values associated with a first set of artifacts in the set of executions. Two subsets of executions from said identified set of executions are selected based on second values associated with a second set of artifacts in the set of executions. One or more markers are identified by determining one or more third set of artifacts from the two subsets of executions that have an associated third value that is different in a first of the two subsets from a second of the two subsets of executions according to a criterion.

摘要： There is provided a method for implementing virtual bases with fixed offsets in a class hierarchy graph corresponding to an object oriented program. The graph has nodes representing object classes and edges representing immediate inheritance therebetween. The method includes the step of determining whether a set N is empty, the set N including all nodes in the graph. A node x is removed from the set N, when the set N is not empty. It is determined whether a set Y is empty, the set Y including nodes that directly and virtually inherit from the node x. A return is made to the step of determining whether the set N is empty, when the set Y is empty. A node y is removed from the set Y, when the set Y is not empty. It is determined whether the node y is duplicated in the graph. A return is made to the step of determining whether the set Y is empty, when the node y is duplicated. An edge e is replaced with an edge e′, when the node y is not duplicated. The edge e represents that the node y virtually inherits from the node x. The edge e′ represents that the node x has a fixed offset with respect to the node y. A return is made to the step of determining whether the set N is empty, upon replacing the edge e.
