  • Patent number: 10664286
    Abstract: A computer system implementing transactional memory. The computing system includes a plurality of Single Instruction Multiple Thread (SIMT) cores and a conflicting address table (CAT) for each core. The CAT stores word addresses for reads and writes correlated with flags indicating whether a corresponding word is written or read by a committing transaction. The CATs for the different SIMT cores are coupled together by an interconnect. A commit unit (CU) is coupled to the SIMT cores and is configured to validate transactions. The cores access its CAT to access a first address of data affected by a first transaction to be committed at the CU. The first address is compared to a second address affected by a second transaction. When the first address matches the second address, the core delays or prevents committing the first transaction at the CU by pausing the first transaction or aborting the first transaction.

  • Patent number: 10469318
    Abstract: Systems and methods commence upon detecting certain computing system specification change events. Changes are recorded in resource usage intent specification records that characterize desired states associated with respective resources of the computing system. The change event causes generation of a data state snapshot of data stored in the computing system. A state tuple is constructed to associate the desired state with the data state. The state tuple is committed to a version control system. At any time, a user or process can select a selected system state tuple from committed tuples stored in the version control system. The tuple is analyzed to determine its associated desired state and its data state. Actions are taken to restore the data state of the tuple to the computing system, and then bringing the computing system to the state of the tuple so as to reproduce the desired system state in the computing system.

  • Patent number: 10423609
    Abstract: Methods and apparatus for identifying consistent snapshot points for file systems in a distributed storage service in which a client may access a file system in backend storage via two or more access nodes. A snapshot coordinator initiates a two-phase commit to perform a snapshot epoch transition. The coordinator sends prepare messages to the nodes. In response, a node sends a response to the coordinator, stops issuing writes to the file system, sets a timer, and waits for a commit message. Upon receiving a response from all nodes, the coordinator sends a commit message. Upon receiving the commit or the timer expiring, the nodes increment an epoch counter and begin issuing writes to the file system tagged with the new epoch and indicating that a copy-on-write operation be performed. The transition is successful if all nodes respond to the request message; otherwise, the two-phase commit is retried.

  • Patent number: 10353759
    Abstract: Processing of transactions within a computing environment is facilitated by taking actions to increase the chances of successfully executing a transaction. A counter is maintained that provides a count of how often a transaction has aborted. The counter increments the count each time the transaction is aborted, and it is reset to zero upon successful completion of the transaction or an interruption leading to no more re-executions of the transaction. If the count reaches a threshold value, then an interrupt is presented and transaction execution is unsuccessful. However, before the count reaches the threshold, a number of actions may be taken to increase the chances of successfully executing the transaction. These actions include actions to be performed within the processor executing the transaction, and/or actions to be performed against conflicting processors.

  • Patent number: 10275347
    Abstract: Methods, systems and computer program products are provided for managing at least one cache for a database. In one method, an operation record is inserted in an operations log for each write operation to the database. The operation record includes a Log Sequence Number (LSN). At least one cache is updated using operation records in the operations log. To update a cache, unapplied operations in the operations log for the cache are identified using an applied LSN associated with the cache. The applied LSN denotes an LSN of a last operation applied to the cache. The unapplied operations are then applied to the cache and the applied LSN is updated with an LSN corresponding to the last unapplied operation of the unapplied operations that were applied to the cache during updating the cache.

  • Patent number: 10223268
    Abstract: A computer system includes transactional memory to implement a nested transaction. The computer system generates a plurality of speculative identification numbers (IDs), identifies at least one of a software thread executed by a hardware processor and a memory operation performed in accordance with an application code. The computer system assigns at least one speculative cache version to a requested transaction based on a corresponding software thread. The speculative ID of the corresponding software thread identifies the speculative cache version. The computer system also identifies a nested transaction in the memory unit, assigns a cache version to the nested transaction, detects a conflict with the nested transaction, determines a conflicted nesting level of the nested transaction, and determines a cache version corresponding to the conflicted nesting level. The computer system also invalidates the cache version corresponding to the conflicted nesting level.

  • Patent number: 10110625
    Abstract: A network security assessment apparatus includes a memory and a processor. The memory stores first, second, and third values of a metric. The metric indicates one or more of a number of network security breaches and a number of fraudulent transactions. The processor chronologically orders the first, second, and third values for the metric over a period of time and compares the first, second, and third values against a threshold to produce first, second, and third results. If the first result is different from the second result or if the second result is different from the third result, the processor increments a volatility count. The processor determines, based on the volatility count, that a control should be implemented to mitigate one or more of the number of network security breaches and the number of fraudulent transactions and in response to that determination, the processor implements the control.
