The CubeSat form-factor limits what can be packed into the device and how much power is available. Without higher-risk deployable solar arrays, a cubesat relies on surface-mounted solar panels to harvest energy. This results in peak available power of about 7.1W.

As we saw with the SOAP paper last time out, even with a fixed model variant and hardware there are a lot of different ways to map a training workload over the available hardware. The following figure highlights how just one of these variables, batch size, impacts throughput and latency on ResNet50. The paper is silent on this issue.

Key Takeaways Distributed storage systems benefit organizations by enhancing data availability, fault tolerance, and system scalability, leading to cost savings from reduced hardware needs, energy consumption, and personnel. Variations within these storage systems are called distributed file systems.

Boosted race trees for low energy classification Tzimpragos et al., We don’t talk about energy as often as we probably should on this blog, but it’s certainly true that our data centres and various IT systems consume an awful lot of it.

This makes the whole system latency sensitive. So we need low latency, but we also need very high throughput: A recurring theme in IDS/IPS literature is the gap between the workloads they need to handle and the capabilities of existing hardware/software implementations. The target FPGA for Pigasus has 16MB of BRAM.
