Video: Cryptocurrency mining raises GPU prices, causes shortage
GPUs are that obscure object of desire right now. Originally created to provide better performance for gamers, now everyone from crypto miners to deep-learning experts wants a piece of them.
Increased demand for cryptocurrency mining and competition for memory modules has created a perfect storm driving GPU prices to skyrocket. That's bad news for users, but great for GPU manufacturers like Nvidia.
We have elaborated on ZDNet on how Nvidia has gone from gamer's delight to AI powerhouse. Just looking at the agenda at GTC, Nvidia's GPU Technology Conference taking place this week in Silicon Valley, confirms this transition.
But why should you care about GPUs if you're not into AI, gaming, or crypto? Because GPUs can also accelerate your databases, and there's not a single organization today not using one.
Massive parallelism through GPUs
GPUs greatly accelerate operations that can be parallelized. This approach has been in use in masively parallel architectures such as Hadoop or Spark for a while now. The idea is to combine an array of database instances, each on a separate server, and then to use a master node that delegates subqueries to each one.
The individual servers execute their subqueries in parallel, get the result sets back to the master node, which combines them and sends a single one back to the client. GPUs make the same divide-and-conquer approach possible within individual servers, with CPUs taking the role of the master node.
