Abstract: A wake-and-go mechanism is provided for a data processing system. When a thread is waiting for an event, rather than performing a series of get-and-compare sequences, the thread updates a wake-and-go array with a target address associated with the event. Software may save the state of the thread. The thread is then put to sleep. When the wake-and-go array snoops a kill at a given target address, logic associated with wake-and-go array may generate an exception, which may result in a switch to kernel mode, wherein the operating system performs some action before returning control to the originating process. In this case, the trap results in other software, such as the operating system or background sleeper thread, for example, to reload thread from thread state storage and to continue processing of the active threads on the processor.

Abstract: Embodiments of the present invention provide an architecture for securely and efficiently executing byte code generated from a general programming language. In particular, a computer system is divided into a hierarchy comprising multiple types of virtual machines. A thin layer of software, known as a virtual machine monitor, virtualizes the hardware of the computer system and emulates the hardware of the computer system to form a first type of virtual machine. This first type of virtual machine implements a virtual operating domain that allows running its own operating system. Within a virtual operating domain, a byte code interpreter may further implement a second type of virtual machine that executes byte code generated from a program written in a general purpose programming language. The byte code interpreter is incorporated into the operating system running in the virtual operating domain.

Abstract: A web service management process includes receiving, by a job server, a request for a web service, sending a request to register a job corresponding to the web service to an administrative service application, and creating, via the administrative service application, a job proxy resource for the job. The job proxy resource is configured to monitor execution of the job. A uniform resource identifier of the job proxy resource is sent to the job server. The process also includes sending, by the job server, information about job lifecycle events, progress, and a request for a current state of administrator actions on a job proxy of the job to the administrative service application. The administrative service application modifies the current state of the job proxy via commands received from an administrative client. The process further includes transmitting the current state of the job proxy to the job server.

Abstract: Disclosed is an improved approach to implement I/O and storage device management in a virtualization environment. According to some approaches, a Service VM is employed to control and manage any type of storage device, including directly attached storage in addition to networked and cloud storage. The Service VM implements the Storage Controller logic in the user space, and can be migrated as needed from one node to another. IP-based requests are used to send I/O request to the Service VMs. The Service VM can directly implement storage and I/O optimizations within the direct data access path, without the need for add-on products.

Abstract: Information about a job is left correctly on a user-by-user basis while minimizing a work load on a user. In a method for controlling a job processing system, a user logs in to a job processing apparatus having an operation unit and a job processing unit and causes the job processing unit to execute a job using the operation unit. The method includes, permitting, in a state in which a first user has been logged in to the job processing apparatus, a second user to log into the job processing apparatus, storing information about a job as information about the second user in a storage unit, in the case where the second user logs in to the job processing apparatus in the state in which a first user has been logged in to the job processing apparatus, and the second user issues an instruction to the job processing unit to execute the job using the operation unit.

Abstract: Various technologies and techniques are disclosed for switching threads within routines. A controller routine receives a request from an originating routine to execute a coroutine, and executes the coroutine on an initial thread. The controller routine receives a response back from the coroutine when the coroutine exits based upon a return statement. Upon return, the coroutine indicates a subsequent thread that the coroutine should be executed on when the coroutine is executed a subsequent time. The controller routine executes the coroutine the subsequent time on the subsequent thread. The coroutine picks up execution at a line of code following the return statement. Multiple return statements can be included in the coroutine, and the threads can be switched multiple times using this same approach. Graphical user interface logic and worker thread logic can be co-mingled into a single routine.

Abstract: A capability is provided for reallocating, to a first borrower that is requesting resources, resources presently allocated to a second borrower. A method for allocating a resource of a system includes receiving a request for a system resource allocation from a first borrower, determining a request priority of the first borrower based on a present resource allocation associated with the first borrower, determining a hold priority of a second borrower based on a present resource allocation associated with the second borrower, and determining, using the first borrower request priority and the second borrower hold priority, whether to reallocate any of the second borrower resource allocation to the first borrower.

Abstract: A computer system provides a way to automatically generate compound commands that perform tasks made up of multiple simple commands. A compound command generation mechanism monitors consecutive user commands and compares the consecutive commands a user has taken to a command sequence identification policy. If the user's consecutive commands satisfy the command sequence identification policy the user's consecutive commands become a command sequence. If the command sequence satisfies the compound command policy, the compound generation mechanism can generate a compound command for the command sequence automatically or prompt an administrator to allow the compound command to be generated. Generating a compound command can be done on a user by user basis or on a system wide basis. The compound command can then be displayed to the user to execute so that the command sequence is performed by the user selecting the compound command for execution.

The template is translated into configuration data adapted to configure each of the system to collectively perform the at least one executable task. The configuration data is applied to the systems through a coupler layer adapted to interface with each of the diverse platforms.

Abstract: Dynamic relocation of virtual machines among hypervisors in a domain is provided. A domain management module is executed on a computer processor and is configured to receive a request to add a new hypervisor to a domain. Each hypervisor and each domain comprises an architecture description (ARD). A new canonical ARD is generated for all hypervisors in the domain. A virtual machine executing on a first system is relocated to any other hypervisor in the domain. Virtual machines may also be moved to out-of-domain hypervisors through the use of override masks. In addition, under certain conditions, new hypervisors additions, as well as hypervisor and system updates may be performed without disrupting the virtual machines that are controlled by the hypervisors.
