Initialization of a Binary:

• Calculate dt_{b_{i}} according to Eq. 22

• Calculate the \eta_b using the condition: (Page 8, right column, second paragaph)

• ETA_B = D_TIME_MIN / (2.0 * min(dt_{b_{i}});

• Initialization of dt = D_TIME_MIN / 2 (Question1: This for everyone? or we just use the minimum?)

La GPU

Vamos a considerar las GPUs nuevas (Tesla K20m), por lo cual es bueno entender un par de detalles acerca del Hardware:

La RAM de la GPU (Memoria Global) es 4800 MB, a esta memoria acceden todas las hebras de las funciones que llamemos, pero el acceso es lento, pues es caro a nivel de hardware, por lo mismolas hebras tienen unas memorias chicas a las cuales pueden acceder más rápido, las cuales no están dentro de la memoria global; éstas son los Registros y la Memoria compartida.
