Dynamic control of prefetching based on prefetching accuracy in a computing system, and related methods and computer readable media. The computing system comprises a processor that includes one or more Central Processing Unit (CPU) cores each having an associated cache memory. The CPU core(s) is configured to generate a value indicative of a prefetching accuracy of the CPU core for prefetching of data, instructions, or both data and instructions from system memory external to the processor for storage in the cache memory for the CPU core and control the prefetching performed by the CPU core based on the value indicative of the prefetching accuracy. In this manner, the number of memory access requests for prefetching is reduced when prefetching accuracy is below a certain threshold, which in turn mitigates memory bandwidth contention, particularly in a multi-CPU core processor.

The subsea fluid transfer system can include first and second end termination assemblies, a plurality of fluid transfer conduits, and a plurality of separator assemblies. The first and second end termination assemblies can each include a mechanical connector first part, a fluid coupler first part, and a fluid header conduit in fluid communication with the fluid coupler first part. The plurality of fluid transfer conduits can be in fluid communication with the fluid header conduit of the first and second end termination assemblies. Each separator assembly can define a plurality of conduit bores therethrough and each fluid transfer conduit can be disposed within a corresponding conduit bore defined each separator assembly. The plurality of separator assemblies can be distributed along a length of the plurality of fluid transfer conduits and configured to maintain a separation distance between adjacent fluid transfer conduits.

A conduit separator assembly and process for using same. The conduit separator assembly can include a centralizer, a first outer part, a second outer part, and a central axle. The centralizer can define a plurality of radial conduit slots. The first outer part can define a plurality of tangential conduit slots. The second outer part can define a plurality of tangential conduit slots. The central axle can be positioned within a central bore defined by the centralizer, a central bore defined by the first outer part, and a central bore defined by the second outer part. The centralizer can be positioned between the first outer part and the second outer part.

For distributing a shared secret (302) among clients, in response to a first request (101, 202, 402) from a first client, a first ephemeral key (309) and one or more further ephemeral keys (310, 311) are generated (305). The shared secret (302) is digitally encapsulated (103) in a first version (313) and one or more further versions (314, 315). Each version (313, 314, 315) is the shared secret (302) encapsulated with the respective ephemeral key (309) and subject to decapsulation with a respective private key, a paired public key of which is known to belong to the respective client. The first (313) and one or more further versions (314, 315) are stored in association with a common identifier (304). When a second request (106, 407, 503, 702) comes from a client identifiable as a holder of one of the private keys and refers to said common identifier (304), that version (313, 314, 315) is transmitted that is subject to decapsulation with the private key of the identified client.
