The Globe and Mail reports in its Saturday edition that in the artificial intelligence field, the computing needs are particularly acute. The Globe's Joe Castaldo writes that the physical infrastructure powering AI -- what people in the industry call "compute" -- is often invisible to the rest of us. Training or building an AI model, especially the large language models (LLMs) that underlie chatbots such as ChatGPT, requires immense computing power. Running an AI application, such as asking ChatGPT a question, has different requirements, but these needs escalate with use. There is huge global demand for computing equipment, especially GPUs, and researchers and entrepreneurs want access to powerful systems to make scientific discoveries and build businesses. That is becoming harder to do in Canada. Canada is ranked fifth in the world for its AI capacity. People from across the AI ecosystem are calling on Ottawa to spend big and they hope the coming federal budget will contain such measures. The solution for Canada is obvious to Denvr Dataworks co-founder Dave King, "We need to build supercomputers." Denvr, based in Calgary, builds and manages infrastructure and software for clients to run AI workloads.
