A method, computer program product, and computer system for implementing tasks on managed nodes. A specified task to be performed by an Ansible module on one or more managed nodes of two or more managed nodes is received. The one or more managed nodes are determined based on an attribute value of a hostDecision attribute of the Ansible module. The attribute value may be primaryNode, allNodes, or Dynamic, where: primary Node requires the one or more managed nodes to be a primary node, allNodes requires the one or more managed nodes to be the two or more managed nodes, and Dynamic requires the one or more managed nodes to be determined dynamically based on runtime information. The Ansible module is sent to the one or more managed nodes to perform the task on the one or more managed nodes.

Automatic selection of nodes on which to perform tasks

A computer-implemented method includes preprocessing, by a compiler, a plurality of macros in a computer program. Preprocessing a macro includes identifying a compile time condition associated with the macro. Preprocessing the macro further includes determining a current value of the compile time condition at the time of compiling a computer instruction and a previous value of the compile time condition. Preprocessing the macro further includes determining a set of computer instructions enclosed by the macro. The method further includes storing a macro information record that includes the compile time condition, the current value and the previous value of the compile time condition, and an identification of the set of computer instructions enclosed by the macro.

An embodiment for cancelling echo in online conference systems is provided. According to some embodiments of the present disclosure, the computer-implemented method comprises, in response to an update of devices of participants in an online conference, dividing, by one or more processors, the devices in an online conference into a plurality of groups, wherein the devices located in a same physical location are divided into a same group. The method also comprises, in response to an update of the devices in an online conference, selecting at least one speaker of the devices in each of the plurality of groups as a representative speaker for each of the plurality of groups. The method further comprises forwarding audio data received from microphones of the devices in one of the plurality of groups to the respective representative speaker of other groups of the plurality of groups.

A system, method and computer program product to refine an original complex CFG into a simpler CFG showing interesting paths and reducing interfering paths with dynamic input for the state of program. The method receives/encodes dynamic user input in the form of annotations which encodes user's special interests or knowledge of the program at run time, e.g., some assumptions of any variables appeared, which can be equations of variable and value or relationships between variables. The method then simplifies all the branching points in a generated AST (Abstract Syntax Tree) whenever possible by querying a SMT (Satisfiability Modulo Theories) solver with branching condition and the user annotations and by evaluating immediate values of expressions or eliminate unreachable parts in the CFG. Finally, the method generates a simplified CFG by simplified AST. This can assist a programmer to understand the code and facilitates correlating different basic blocks under a same scenario.

A method for filtering out nodes associated with hierarchical data structures is provided. The method may include generating node controllers on the hierarchical data structures. The method may include determining whether user actions are received on a first node controller, a second node controller, and a third node controller associated with the generated plurality of node controllers. The method may include filtering node levels associated with hierarchical data structures, and presenting the hierarchical data structures without the filtered out node levels. The method may include filtering out sibling nodes associated with the hierarchical data structures, and presenting the hierarchical data structures without the filtered out sibling nodes. The may further include reverse-collapsing first node levels and filtering out second node levels based on the reverse-collapsed first node levels, and presenting the hierarchical data structures without the filtered out second node levels.
