The reproduction of two species of Cichla (Cichla cf. ocellaris and C. monoculus, commonly known in Brazil as tucunaré) introduced in the Volta Grande Reservoir, southeastern Brazil, was analyzed. The period for spawning began at the end of the dry season (September) and extended until the end of the rainy season (January). The length of the first gonad maturation (L50) and the length at which ...

We explore the floating-point arithmetic implemented in NVIDIA tensor cores, which are hardware accelerators for mixed-precision matrix multiplication available on Volta, Turing, and Ampere microarchitectures. Using Volta V100, Turing T4, A100 graphics cards, we determine what precision is used intermediate results, whether subnormal numbers supported, rounding mode used, order operations under...
