摘要： A system, method and computer program product are provided for supporting Transactional Memory communications. In one embodiment, the system comprises a transactional memory host with a host transactional memory buffer, an endpoint device, a transactional memory buffer associated with the endpoint device, and a communication path connecting the endpoint device and host. Input/Output transactions associated with the endpoint device executed in transactional memory on the host are stored in both the host transactional memory buffer and the transactional memory buffer associated with the endpoint device. In an embodiment, the Transactional Memory system further comprises an intermediate device located on the communication path between the host and the endpoint device, and an intermediate transactional memory buffer associated with said intermediate devices. In this embodiment, the Input/Output transactions associated with said endpoint device are stored in the intermediate transactional memory buffer associated with the intermediate device.

摘要： A system for predicting an occurrence of a critical even in a computer cluster includes: a control system that includes an event log, a system parameter log, a memory for storing information related to occurrences of critical events, and a processor. The processor implements a hybrid prediction system; loads the information from the event log and the system performance log into a Bayesian network model; uses the Bayesian network model to predict a future critical event; makes future scheduling and current data migration selections; and adapts the Bayesian network model by feeding the scheduling and data migration selections.

摘要： A system and method for managing clustered computer resources, and more particularly very large scale clusters of computer resources by a semi-hierarchical n level, n+1 tier approach. The top level consists of the controller nodes. A first tier is defined at the top level. At a last level, at which the cluster of controlled nodes is found, a last tier is defined. Additional levels of controller or controlled nodes may exist between the top and bottom levels. At least one intermediate tier is introduced between two of the levels and comprises at least one proxy or a plurality of proxies. A proxy is a process or set of processes representing processes of the clustered computer resources. Proxies can run either on controller nodes or on the controlled nodes or controlled node clusters to facilitate administration of the controlled nodes.

摘要： A hybrid method of predicting the occurrence of future critical events in a computer cluster having a series of nodes records system performance parameters and the occurrence of past critical events. A data filter filters the logged to data to eliminate redundancies and decrease the data storage requirements of the system. Time-series models and rule based classification schemes are used to associate various system parameters with the past occurrence of critical events and predict the occurrence of future critical events. Ongoing processing jobs are migrated to nodes for which no critical events are predicted and future jobs are routed to more robust nodes.

摘要： Mechanisms are provided, in a data processing system having a processor and a transactional memory, for executing a transaction in the data processing system. These mechanisms execute a transaction comprising one or more instructions that modify at least a portion of the transactional memory. The transaction is suspended in response to a transaction suspend instruction being executed by the processor. A suspended block of code is executed in a non-transactional manner while the transaction is suspended. A determination is made as to whether an interrupt occurs while the transaction is suspended. In response to an interrupt occurring while the transaction is suspended, a transaction abort operation is delayed until after the transaction suspension is discontinued.

摘要： A pointer is for pointing to a next-to-read location within a stack of information. For pushing information onto the stack: a value is saved of the pointer, which points to a first location within the stack as being the next-to-read location; the pointer is updated so that it points to a second location within the stack as being the next-to-read location; and the information is written for storage at the second location. For popping the information from the stack: in response to the pointer, the information is read from the second location as the next-to-read location; and the pointer is restored to equal the saved value so that it points to the first location as being the next-to-read location.

摘要： A mechanism is provided for reducing a penalty for executing a correct branch of a branch instruction. An execution unit in a processor of a data processing system executes a first branch of the branch instruction from a main thread of a processor and executes a second branch of the branch instruction from an assist thread of the processor. The execution unit determines whether the main thread is a correct branch of the branch instruction or the assist thread is the correct branch of the branch instruction. Responsive to the assist thread being the correct branch of the branch instruction, the execution unit pauses execution of the branch instruction on both the main thread and the assist thread. The execution unit then properly inherits a context of the main thread in order that execution of the second branch may continue.

摘要： A mechanism is provided for redundant execution of a set of instructions. A redundant execution begin (rbegin) instruction to be executed by a first hardware thread on the first processor is identified in the set of instructions. The set of instructions immediately after the rbegin instruction are executed on the first hardware thread and on a second hardware thread. Responsive to both the first processor and the second processor ending execution of the set of instructions, responsive to a first set of cache lines in a first speculative store matching a second set of cache lines in a second speculative store, and responsive to a first set of register states in a first status register matching a second set of register states in a second status register, dirty lines in the first speculative store are committed thereby committing a redundant transaction state to an architectural state.
