Monitoring systems with predictive failure analysis technology (e.g., Self Monitoring Analysis and Reporting Technology (S.M.A.R.T)) operate on the basis of correlations between the hard disk's mechanical and electronic characteristics. Using wavelet transforms to analyze electrical signals from the hard disks can help better determine changes in values and trends in various hard disk characteristics. Using wavelet transforms allows for thorough and deeper analysis of the electrical signals from the hard disks. Wavelet analysis can be performed on the electrical signal to extract time and frequency information associated with the low and high frequency components. Analyzing the extracted components of the electrical signal can indicate a presence and position of one or more mechanical defects on the hard disk.

The method of the present invention provides an automatic and optimised selection of the network topology for distributing scheduling of jobs on the computers of the modified network topology. The automatic and optimised selection of the network topology starts from the current topology and a desired number of additional connections. In this way the method of the present invention provides a higher convergence speed for the modified consensus algorithm in comparison, e.g., to a simple ring network. The method exploits the so called small-world networks. Small-world networks are more robust to perturbations than other network architectures. The preferred embodiment provides a workload scheduling system which is highly scalable to accommodate increasing workloads within a heterogeneous distributed computing environment. A modified average consensus algorithm is used to distribute network traffic and jobs amongst a plurality of computers.

Computer-implemented methods, computer program products and systems for a scalable workload scheduling system to accommodate increasing workloads within a heterogeneous distributed computing environment. In one embodiment, a modified average consensus method is used to evenly distribute network traffic and jobs among a plurality of computers. The user establishes a virtual network comprising a logical topology of the computers. State information from each computer is propagated to the rest of the computers by the modified average consensus method, thereby enabling the embodiment to dispense with the need for a master server, by allowing the individual computers to themselves select jobs which optimally match a desired usage of their own resources to the resources required by the jobs.

An optimizer mechanism to increase battery length for mobile devices is provided. An operational state of a data processing system, e.g., a mobile device, is adjusted so as to achieve a target time period of operation when the data processing system is using a depleting power supply. A predicted power consumption of individual processes executing on the data processing system is determined and a remaining amount of power that the depleting power supply can provide is also determined. A subset of processes whose execution can be suspended is determined so that the data processing system can operate for the target period of time based on the predicted power consumption of the individual processes and the amount of power that the depleting power supply can provide. The identified subset of processes are placed in a suspended execution state.

A method for local archiving of e-mail messages in an e-mail client application according to various exemplary embodiments can include generating a mail thread including at least two e-mail messages transmitted and received between a message originator and at least one recipient; appending e-mail identification data into a header of the at least two e-mail messages when transmitted. The method may also include archiving related e-mail messages within the mail thread in an e-mail client application, comprising: searching for the related e-mail messages by identifying each e-mail message having a same message originator field; and merging non-redundant segments of each e-mail message into a single message document hierarchically by response level and timestamp. The method may further include displaying, on a display screen, the single message document according to a conversational view based upon a perspective of the response level of a user within the mail thread.

A mechanism is provided for performing secure system access by a requesting user without sharing a password of a credential owner. A database stores system information for resources. The owner of super user authority for a resource provides system information to the database including a credential for accessing the resource. When a user wishes to access the system, client software of the requestor sends an access request to client software of the owner. The client software of the owner prompts the owner to authorize or deny access. Responsive to the owner authorizing the access, the client software of the owner returns authorization to the client software of the requestor, which then uses the credential in the system information database to access the resource. The client software of the requestor does not cache or store the credential or present the credential to the user.
