A device, system, and method are directed towards managing threads in a computer system with one or more processing units, each processing unit having a corresponding hardware resource. Threads are characterized based on their use or requirements for access to the hardware resource. The threads are distributed among the processing units in a configuration that leaves at least one processing unit with threads that have an aggregate zero or low usage of the hardware resource. Power may be reduced or turned off to the instances of the hardware resource that have zero or low usage. Distribution may be based on one or more of a number of specifications or factors, such as user power management specifications, power usage, performance, and other factors.

A system for discussion thread management using tag-based categorization, in which three types of tags are provided together to enable effective categorization of discussion threads, based on both automated and manual tagging. The three tag types are 1) user-defined tags, 2) moderator-promoted tags, and 3) system-generated tags. User-defined tags are arbitrarily defined by individual users and associated by users with posts to meet specific user needs. System-generated tags are automatically generated for each sub-thread to summarize a post and all the replies beneath it. System-generated tags can be promoted to a moderator-promoted tags when a moderator user verifies the correctness of a system-generated tag. The disclosed system detects topic changes in discussion threads based on the tags associated with each post in the thread. A moderator can manually examine sub-threads that have been determined to be off topic, and take appropriate actions. For example, a moderator may delete an off topic post or sub-thread, or fork a new thread of discussion for an off-topic sub-thread. Such processing of off-topic sub-threads can alternatively be made by the disclosed system automatically, without moderator intervention. Moderators can also define policies to control discussion moderation based on the disclosed tags and off-topic determinations.

Described is an application program interface (API) that enables dynamic modification to applications executing in a heterogeneous distributed computing environment. The application program interface includes a navigation function, a query function, a thread management function, and a modifier function. The navigation function returns program information for a local or remote computer (i.e., specified computing device). The query function returns information about a program on the specified computing device. The thread management function controls execution of other programs on the specified computing device. The modifier function modifies a system memory on the specified computing device that stores the heterogeneous program. The API works in conjunction with a hierarchical intermediate representation of the heterogeneous program such that pre-defined program tools can modify the intermediate representation and write these modifications to the specified computing device while the heterogeneous program remains operational.

The present invention provides various simple and easy ways for each end user to manage the thread in a way that suits them. In some cases, the user experience requires only a single click. Additional embodiments allow user to manage inbox space, recover suppressed threads, be alerted on contextual changes of such threads, and so forth. The system allows the user to specifically configure his / her own email thread management scheme by selecting an email and choosing “Suppress Thread” on his / her user interface. The system then performs a number of steps such as examining the <message-id> and <references> headers of the selected email to configure the suppress filter. Once configured, the system will examine each email as it is received and examine its <message-id> and <references> headers per RFC 822. If the headers match the configured <messageid> and <responses> headers, the emails will be suppressed in the manner chosen by the user such as deletion or move to folder.

A CPM user can simply start a message-based conversation with another CPM or Short Message Service (SMS) user without explicitly establishing a session beforehand. All messages that belong to a given conversation are displayed in the corresponding conversational view (i.e. window) in the CPM user device, even if the conversation is stopped and restarted at a later time, and even if there are multiple message threads available (currently active or stored) in the CPM device. Message structures and behavior of the CPM system elements to enable the functionalities above as well as a mechanism makes the message threads management possible even between a CPM user and an SMS user are also provided.

In one embodiment of the present invention, a streaming multiprocessor (SM) uses a tree of nodes to manage threads. Each node specifies a set of active threads and a program counter. Upon encountering a conditional instruction that causes an execution path to diverge, the SM creates child nodes corresponding to each of the divergent execution paths. Based on the conditional instruction, the SM assigns each active thread included in the parent node to at most one child node, and the SM temporarily discontinues executing instructions specified by the parent node. Instead, the SM concurrently executes instructions specified by the child nodes. After all the divergent paths reconverge to the parent path, the SM resumes executing instructions specified by the parent node. Advantageously, the disclosed techniques enable the SM to execute divergent paths in parallel, thereby reducing undesirable program behavior associated with conventional techniques that serialize divergent paths across thread groups.

Thread switching prevents pipeline stalls when executing multiple threads. An analysis of a first thread identifies instructions capable of causing pipeline stalls. If pipeline stalls from the identified instructions are likely, thread switching instructions are added to the first thread in place of the identified instructions. Thread switching instructions direct a microprocessor to suspend executing the thread and begin executing a second thread. Thread switching instructions can be added to the second thread to enable the resumption of the first thread at the location specified by the identified instruction. The thread switching instructions are configured to avoid pipeline stalls when switching threads. Thread switching instructions can store and retrieve thread-specific information upon the suspension and resumption of threads. Thread switching instructions can schedule the execution of two or more threads in accordance with load balancing schemes. Threads can be modified using static or dynamic code analysis and modification techniques.
