DescriptionThe Open Community Runtime specification prescribes the
way a task-parallel application has to be written, in
order to give the runtime system the ability to
automatically migrate work and data, provide fault
tolerance, improve portability, etc. These constraints
prevent an application from efficiently starting a new
process to run another external program. We have
designed an extension of the specification which
provides exactly this functionality in a way that fits
the task-based model. The bulk of our work is devoted to
exploring the way the task-parallel application can
interact with an external application without having to
resort to using files on a physical drive for data
exchange. To eliminate the need to make changes to the
external application, the data is exposed via a virtual
file system using the filesystem-in-userspace
architecture.
