1. A method comprising: receiving, by a server device, an application that is to be executed by a graphics processing unit (GPU) that resides on a device external to the server device; determining, by the server device, that the application would execute inefficiently on the GPU; creating, by the server device and based on the determination that the application would execute inefficiently on the GPU, a modified version of the application that would execute more efficiently on the GPU than the received application; performing, by the server device an analysis of the modified version of the application during execution of the modified version of the application on the server device, wherein performing the analysis comprises: executing a virtual GPU model; executing the modified version of the application on the virtual GPU model; and monitoring functionality of the virtual GPU model during execution of the modified version of the application on the virtual GPU model; determining whether the modified version of the application satisfies one or more performance criteria based on the analysis; and transmitting, to the device, the modified code of the application and a validation of the application if the application satisfies the one or more performance criteria.
