摘要： A method for testing computer programs including defining one or more selected force stop points for a target computer program. For each of the selected force stop points the target computer program is executed in a force stop mode and executed again in a non-force stop mode. Input to execution in the force stop mode includes the selected force stop point. The target program is terminated as a result of execution in the force stop mode when the selected force stop point has been reached. Executing in the force stop mode results in a residual environment. The target computer program is executed in a non-force stop mode in the residual environment. Output from executing in a non-force stop mode includes test result data. For each of the selected force stop points it is determined if the test result data is consistent with expected test results.

摘要： Exemplary embodiments include a method, system, and storage medium for managing computer processing functions in a multi-processor computer environment that includes a standard logical processor and an assist logical processor, each of which share the same operating system instance within a logical partition. The method includes invoking a switch-to service by standard code. The standard code is running on a standard logical processor and is executing a task. The switch-to service checks to see if an assist logical processor is online, and it if finds one, the switch-to service updates an integrated assist field of a work element block associated with the task and assigns a queue to the work element block. The task is dispatched, in accordance with business rules identified in a system control block, on either of said assist logical processor or said standard logical processor.

摘要： A method and apparatus for ensuring that a process interacting with a failing process is notified of the failure of that process. Each process has a unique process identifier (PID) associated with it. Each process optionally has an affinity list containing one or more entries, each of which contains the identifier of a process that is to be notified when the process fails. A process updates the affinity list of a target process (either itself or another process) by calling an affinity service of the operating system (OS) kernel, specifying the type of operation (add or delete), the identifier of the target process, the identifier of the process that is to notified, and the type of event that is to be generated for the process that is to be notified. When a process fails, a process termination service of the OS kernel examines the affinity list of the failing process and, for each entry in the list, generates an event of the specified type for the process specified as to be notified.

摘要： In a client/server system, a method and apparatus for a listening daemon to distribute work and client connectivity across multiple processes each supporting multiple threads. Upon receiving a request from a client, a listening daemonaccepts the conversation, thus creating a socket. The listening daemon then does a putwork( ) call which places a work request on a system managed work queue. The work request behaves in a manner very similar to spawn in that it provides for parameters to be passed as well as transfer of ownership of the socket. In the meantime, server processes that are created either manually or by the operating system create multiple threads, which invoke a getwork( ) service to retrieve work requests created by the listening daemon. The getwork( ) service transfers the socket to the calling process and notifies the thread which file descriptors it has inherited. The thread is then able to process the client request and respond directly to the client without requiring an intermediate process to provide the communication link. The present invention allows a server in a client/server system to spread the workload across multiple threads in multiple processes, avoiding the creation of too many processes or too many threads in a single process. The direct transfer of the socket eliminates the unnecessary overhead typically required to rebind a new process to the client application.
摘要翻译：在客户机/服务器系统中，用于监听守护进程的方法和装置在跨多个进程分发工作和客户端连接，每个进程支持多个线程。一旦接收到来自客户端的请求，一个侦听守护进程接听对话，从而创建一个套接字。然后，监听守护程序执行putwork（）调用，将工作请求放在系统管理的工作队列上。工作请求的行为方式非常类似于生成，它提供要传递的参数以及套接字的所有权传输。同时，由手动或由操作系统创建的服务器进程创建多个线程，该线程调用getwork（）服务来检索由监听守护程序创建的工作请求。 getwork（）服务将套接字传输给调用进程，并通知线程其继承的文件描述符。线程然后能够处理客户端请求并直接响应客户端，而不需要中间过程来提供通信链路。本发明允许客户机/服务器系统中的服务器在多个进程中跨多个线程传播工作负载，避免在单个进程中创建太多进程或太多线程。套接字的直接传输消除了将新进程重新绑定到客户端应用程序所需的不必要开销。

摘要： A method and apparatus for controlling the assignment of units of work to workload enclaves in a client/server system in which units of work are organized into enclaves with the units of work in each enclave being managed as a single entity. Incoming work requests are queued for processing by one or more worker threads of one or more server processes. In response to the receipt of an incoming work request, a putwork() service of the operating system kernel defines an workload enclave for the work request and adds the work request to a queue of incoming work requests to enqueue the request. In response to a request from a worker thread for more work, a getwork() service of the operating system kernel removes a work request from the queue to dequeue the request and associates the worker thread with the enclave defined for the request. If a worker thread must create a new unit of work while processing a work request, it calls an appropriate service of the operating system kernel, which creates the new unit of work and associates the new process with the enclave of the worker thread. The worker thread is disassociated from the enclave upon completion of the work request.

摘要： A method and apparatus for fully restoring the context of a user program, including program status word (PSW) and CPU register contents, following an asynchronous interrupt. Upon the occurrence of an asynchronous interrupt event, control is transferred from the normally executing part of the user program to an interrupt handler of the operating system kernel. The kernel interrupt handler saves the contents of the CPU registers and PSW as they existed at the time of the interrupt in a save area associated with the user program before transferring control to a signal catcher routine of the user program. When it has finished handling the interrupt, the signal catcher routine restores the previous state of program execution as it existed before the interrupt by storing the address of the save area in a selected register (which may be a general register/access register pair), restoring the contents of the registers other than the selected register containing the address of the save area, and then restoring the contents of the PSW and selected register by using a new Resume Program (RP) instruction. The RP instruction contains an operand field specifying through the selected register the base address of the save area together with offset fields specifying the offsets of the saved contents of the PSW and selected register relative to the beginning of the save area. Upon decoding an RP instruction, the CPU executing the instruction adds the displacement to the base address contained in the specified register to form the beginning address of the save area, to which it adds the specified offsets to access the saved PSW and selected register contents. The current PSW and selected register contents are then restored with the saved contents to fully restore the previous program context and return control to the instruction being executed at the point of interrupt. To ensure system integrity, only those fields of the PSW are restored that could have otherwise been restored by a program operating in problem state.
