The systems aboard the Crew Dragon do not use multicore capabilities of a processor. Instead, they perform each computation separately on the two cores, comparing results. The three flight computers with dual-core processors installed act as six independent computers, constantly verifying each other's calculations and computations[3]. The GUI for astronauts is Chromium-based JavaScript[3]. While specific information about GPU usage on SpaceX spacecraft is not readily available, it is worth noting that SpaceX uses GPGPU clusters for computing through its most challenging tasks[14]. GPGPU computing has played a pivotal role in powering the world's fastest supercomputers and has been crucial for the development of modern, data-rich systems[14].
