    Abstract: A system, processor and method to increase computational reliability by using underutilized portions of a data path with a SuperFMA ALU. The method allows the reuse of underutilized hardware to implement spatial redundancy by using detection during the dispatch stage to determine if the operation may be executed by redundant hardware in the ALU. During execution, if determination is made that the correct conditions exists as determined by the redundant execution modes, the SuperFMA ALU performs the operation with redundant execution and compares the results for a match in order to generate a computational result. The method to increase computational reliability by using redundant execution is advantageous because the hardware cost of adding support for redundant execution is low and the complexity of implementation of the disclosed method is minimal due to the reuse of existing hardware.

    Abstract translation: 一种通过使用SuperFMA ALU通过使用数据路径的不充分部分来增加计算可靠性的系统，处理器和方法。 该方法允许利用未充分利用的硬件来重新利用在调度阶段使用检测来实现空间冗余，以确定该操作是否可以由ALU中的冗余硬件执行。 在执行期间，如果确定冗余执行模式所确定的正确条件，SuperFMA ALU将执行冗余执行操作，并比较匹配结果以生成计算结果。 通过使用冗余执行来增加计算可靠性的方法是有利的，因为对冗余执行的添加支持的硬件成本低，并且由于现有硬件的重用而使所公开的方法的实施的复杂度最小。

    Abstract: Avoiding encryption in a deduplication vault. In one example embodiment, a method may include analyzing an allocated plain text block stored in the source storage to determine if the block is already stored in the deduplication storage, in response to the block not being stored, encrypting the allocated plain text block and analyzing the encrypted block to determine if the encrypted block is already stored in the deduplication storage, analyzing a second allocated plain text block stored in the source storage to determine if the block is already stored in the deduplication storage, in response to the block already being stored, avoiding encryption of the second allocated plain text block by not encrypting the second allocated plain text block and instead associating the location of the second allocated plain text block in the source storage with the location of the duplicate block already stored.

    Abstract: Avoiding encryption of certain blocks in a deduplication vault. In one example embodiment, a method of avoiding encryption of certain blocks during a backup of a source storage into a deduplication vault storage may include analyzing each allocated plain text block stored in a source storage at a point in time to determine if the allocated plain text block is already stored in the deduplication vault storage. If the allocated plain text block is not stored in the deduplication vault storage, the block may be encrypted and the encrypted block may be analyzed to determine if the encrypted block is already stored in the deduplication vault storage. If neither the allocated plain text block nor the encrypted block is already stored in the deduplication vault storage, the encrypted block may be stored in the deduplication vault storage.
