In various embodiments, an ordered atomic operation enables a parallel processing subsystem to executes an atomic operation associated with a memory location in a specified order relative to other ordered atomic operations associated with the memory location. A level 2 (L2) cache slice includes an atomic processing circuit and a content-addressable memory (CAM). The CAM stores an ordered atomic operation specifying at least a memory address, an atomic operation, and an ordering number. In operation, the atomic processing circuit performs a look-up operation on the CAM, where the look-up operation specifies the memory address. After the atomic processing circuit determines that the ordering number is equal to a current ordering number associated with the memory address, the atomic processing circuit executes the atomic operation and returns the result to a processor executing an algorithm. Advantageously, the ordered atomic operation enables the algorithm to achieve a deterministic result while optimizing latency.

Versions of a service not reachable by a set of service requestors that use the service are removed. Multiple, different versions of a service are stored, along with metadata associated with the multiple, different versions of the service. The metadata is examined to determine one or more of the multiple, different versions of the service that are not reachable by the set of service requestors that use the service. Those versions are deleted.

Systems and methods are disclosed for automatically generating and publishing API information for web services, and for informing a requestor for the web services of a correct format of the request. One embodiment comprises an API gateway that identifies a plurality of software code objects for deployment, where the code objects include executable code for performing functions. The API gateway receives a request for a web service from an application, queries a code object for usage information regarding a function to perform the web service, and determines that a format of the request for the web service is incorrect based on the query for the usage information. The API gateway transmits a response to the application that specifies a correct format of the web service request based on the query, and receives a subsequent request from the application that specifies the correct format for the web service request.
