Abstract: Systems, apparatuses, and methods for intentionally delaying servicing of interrupts in a computing system are disclosed. A computing system includes a processor that services interrupts generated by components of the computing system. An interrupt controller detects a received interrupt and intentionally delays servicing of the interrupt depending on various conditions. If the interrupt is a first type of interrupt and the processor is in a first power state, servicing of the interrupt is delayed by a first period of time. If the interrupt corresponds to the first type of interrupt and the processor is in a second power state, servicing of the interrupt is delayed for a period of time that is longer than the first period of time. If a non-maskable interrupt is received before expiration of either the first or second period of time, then servicing of any previously delayed interrupts is allowed to proceed.

Abstract: Near clones for a set of targeted computing systems are provided by determining a highest common denominator set of components among the computing systems, producing a pseudo-clone configuration definition, and realizing one or more pseudo-clone computing systems as partially configured backups for the targeted computing systems. Upon a planned failover, actual failure, or quarantine action on a targeted computing system, a difference configuration is determined to complete the provisioning of the pseudo-clone system to serve as a replacement system for the failed or quarantined system. Failure predictions can be used to implement the pseudo-clone just prior to an expected first failure of any of the targeted systems. The system can also interface to an on-demand provisioning management system to effect automated workflows to realize pseudo-clones and replacement systems automatically, as needed.

Abstract: Techniques are provided for the detection of malicious software (malware) on a general purpose computing device. A challenge in detecting malicious software is that files are typically scanned for the presence of malicious intent only once (and subsequent rescanning is typically performed in a simplistic manner). Existing methods in the art do not address how to most effectively rescan collections of files in a way that tries to optimize performance and efficacy. These methods may also be useful if additional information is now available regarding a file that might be useful to an end-user or an administrator, even though the file's core disposition might not have changed. More specifically, we describe methods, components, and systems that perform data analytics to intelligently rescan file collections for the purpose of retroactively identifying malware and retroactively identifying clean files.

If no failure, a next interim version is tested that represents the point at which approximately one half the changes were introduced between the previous successfully tested version and the first interim version tested.

Abstract: A data processing apparatus (4) includes processing circuitry (6) for executing program instructions that form part of a transaction which executes to generate speculative updates and to commit the speculative updates if the transaction completes without a conflict. Instruction sampling circuitry (44) captures instruction diagnostic data (IDD) relating to execution of a sampled instruction. Transaction tracking circuitry (46) detects if the sampled instruction is within a transaction and if so, tracks whether the speculative updates associated with the transaction are committed and captures transaction diagnostic data (TDD) indicative of whether or not the speculative updates were committed. Thus, both instruction diagnostic data relating to a sampled instruction and transaction diagnostic data relating to the fate of a transaction containing a sampled instruction are captured.
