Wetin na fizik-bɛs GPU ray traysa ɛn wetin mek i impɔtant?

Wan GPU ray traysa we de bays pan fizik de simul aw layt de biev na di rial wɔl — de tray rayt frɔm wan vayrɔyal kamɛra, bounce dɛn ɔf sɔfays, ɛn kɔmpyutayt kɔrɛkt kɔlɔ ɛn shed.

Wetin mek fɔ impruv wan rayt traysa na Julia instead ɔf C++ ɔ CUDA?

Julia de gi ay-pafɔmɛnshɔn numɛrik kɔmpiutishɔn wit sɛntaks fa fawe we pɔsin kin rid pas C++, we mek i bi wan kɔmplit chuk fɔ grafik risach.
