Up to some degrees, you can run unmodified application to take
advantage of openSSI. The kind of such apps is the one who forks some
numbers of child processes (multi thread or multi processing). Please
remember openSSI can only migrate process. Threads will be migrated
all together.

Or, you can do it with so called "parametric execution". For example
run 10 instance of application A, each is fed with differrent
parameters. Run them then collect the results. One of the example of
such scenario is batch scheduler (e.g running distributed rendering).
