Abstract

The use of cloud computing in high performance computing has raised questions about the advantage of this type of system over on-premises systems. However, comparing these two systems is not trivial, due to several factors such as the number of solutions that cloud computing providers offer and also the behavior of the application. This study aimed to analyze the numerical weather prediction model BRAMS in both systems. For a small case study, the application performs similarly across systems. The cost of running the application in different markets offered by AWS was also analyzed, which for the problem used, it is advisable to use the spot market.
