Cloud Native Architecture on the SKA SDP

The nature of the workloads on the Science Data Processor of the SKA has provided an opportunity to re-imagine what scheduling and resource management could look like for HPC.  Some of the associated research has focused on Containerisation and Container Orchestration including Kubernetes where the principles of abstraction, encapsulation and efficient task packing stand to provide benefits throughout the hardware and software ecosystem.  An overview of the discoveries are discussed in the SDP Memo_ 051 – Cloud Native Applications on the SDP Architecture  .

AXI over Ethernet (AXIoE) Base Specification

AXIoE is a packet format and network protocol for executing ARM AMBA 4 AXI standard bus style memory transactions on a remote device connected through an Ethernet network. AXIoE was designed with the goals of: Resource efficient server implementations in embedded devices. Reliable and in-order access to the register/memory bus of the remote device to simplify the access patternsand error handling requirements of application software. Efficient use of the network for bulk data transport. Decode and Encode transactions in a serial data streaming manner. Mirror the functionality of the AMBA AXI-4 memory bus. The name AXIoE is an acronym for Read more …
