Abstract: Methods, non-transitory machine readable media, and computing devices that provide more efficient hierarchical propagation in tree structures are disclosed. With this technology, a first delta record for a first interior node is created optionally in an atomic transaction along with updating a first tally record for a leaf node based on a first value. The transaction is in response to an action associated with the leaf node and the first interior node is a parent of the leaf node in a hierarchical tree. A timer associated with the first delta record is then set. A second value is updated in a second tally record for the first interior node based on the first value, when the timer has expired. Accordingly, this technology advantageously maintains recursive properties or values throughout a hierarchical tree continually, with reduced cost, even in a distributed network and in hierarchical trees with large numbers of nodes.

Abstract: Techniques for harmonic-resistant file striping are described. In one embodiment, for example, an apparatus may comprise a processor circuit and a storage medium comprising instructions for execution by the processor circuit to receive a request to write data to a file at a specified offset, determine a stripe identifier (ID) based on the specified offset according to a harmonic-resistant striping order, and initiate a write procedure to cause the data to be written to a stripe of the file, the stripe corresponding to the stripe ID. Other embodiments are described and claimed.
