GPUs are not allowed in F1 computational fluid dynamics because the FIA, Formula 1's governing body, imposes strict regulations on the use of technology in the sport. These regulations limit the number of teraflops a team can use for simulating car aerodynamics and stipulate that only CPUs can be utilized, not GPUs1. This is to ensure a level playing field and prevent wealthier teams from gaining an unfair advantage through the use of more powerful computing resources.
Track-side conditions in F1 racing pose several challenges to technology, including high temperatures and humidity, which impact both drivers and the performance of electronic devices. These harsh conditions necessitate regular replacement of hardware every three years due to increased failure rates. Additionally, the demanding environment requires efficient cooling systems for the cars and equipment, while teams must also manage the effects of varying weather conditions on race strategies and vehicle performance.
Formula 1 teams generally replace their technology every three years to deal with the physical demands on track-side hardware. These demands include traveling around the world and dealing with high humidity and temperatures at certain tracks.
