@section starting_components Typical Study based on SimGrid
- The studied **Application**. This can be either a distributed
algorithm described in our simple APIs, or a full featured real
- parallel application using the MPI interface (or other).
+ parallel application using for example the MPI interface
+ @ref application "(more info)".
- The **Virtual Platform**. This is a description of a given
distributed system (machines, links, disks, clusters, etc). Most of
Platform with a Dynamic Scenario where for example the links are
slowed down (because of external usage), the machines fail. You
have even support to specify the applicative workload that you want
- to feed to your application.
+ to feed to your application @ref platform "(more info)".
- The application's **Deployment Description**. In SimGrid terminology,
the application is an inert set of source files and binaries. To
make it run, you have to describe how your application should be
- deployed on the virtual platform. Specify which process is located
- on which host, along with its parameters.
+ deployed on the virtual platform. Specify which process is mapped
+ on which host, along with its parameters
+ @ref deployment "(more info)".
- The **Platform Models**. They describe how the virtual platform
reacts to the actions of the application. For example, they compute
the time taken by a given communication on the virtual platform.
These models are already included in SimGrid, and you only need to
- pick one and maybe tweak its configuration to get your results.
