Abstract: Systems and methods for managing locks in a data acquisition system with a distributed data storage are disclosed. In embodiments, a storage node of a data acquisition system with a plurality of storage nodes receives a request for an unprocessed event, where portions of the event data are stored across the plurality of storage nodes. One node of the plurality of nodes holds the lock value for the event. The node receiving the request searches for an event where it stores the lock value that is unlocked. If none is found, the node receiving the request forwards the request to a second node, which repeats the search.

Abstract: Examples may include techniques to manage data in a data acquisition system including allocating memory in a first stage buffer; storing data received by a data provider into the allocated memory in the first stage buffer; and storing a key identifying the stored data and an address in the first stage buffer for the stored data in an entry in a first keys data structure. Further steps include receiving a request from a filtering unit to get the stored data from the first stage buffer, the request including the key; retrieving the address in the first stage buffer from the entry in the first keys data structure associated with the key; and returning the address in the first stage buffer to the filtering unit.

Abstract: Examples may include a non-volatile memory having a memory including a first table of device physical addresses and a second table of physical device addresses; a control register to receive a clone command to clone a second memory region of the memory as a copy of a first memory region of the memory, the first and second memory regions being referenced by different device physical addresses; and address translation logic, upon receipt of the clone command, create a first entry in the first table for each page of the first memory region and create a second entry in the first table for each page of the second memory region, each first table entry for the first memory region and each first table entry for the second memory region pointing to a same entry in the second table.
