WebInstalling cyclictest (and other required packages) on the device We intend to run test cases via t he cyclictest app against both the standard and the newly minted RTL kernel. This implies, of course, that we must first obtain the cyclictest sou rces and build it on the device (note that the work here is being carried out on the Raspberry Pi). WebSep 7, 2024 · Cyclictest, which uses a hardware-based timer to measure platform latency and jitter, demonstrated that the latency on both vSphere 7.0U3 RC and on bare metal was less than 10 microseconds. A 10-microsecond latency is well within the latency requirements of RAN workloads. hdfc bhongir ifsc code https://milton-around-the-world.com
