Through this study, we will measure how the collective MPI operations behaves in virtual and physical clusters, and its impact on the application performance. As we stated before, we will use as a test case the Weather Research and Forecasting simulations.A través de este estudio vamos a medir cómo las operaciones colectivas de MPI se comporta de clusters virtuales y físicos, y su impacto en el rendimiento de las aplicaciones. Como dijimos antes, vamos a utilizar como prueba las simulaciones del modelo de Weather Research and Forecasting.A través d'aquest estudi mesurarem com les operacions col·lectives de MPI es comporten de clústers virtuals i físics, i el seu impacte en el rendiment de les aplicacions. Com hem dit abans, utilitzarem com ...
