MPI profilers). You can reuse this mechanism for any kind of trace
that you want to replay, for example to study how a P2P DHT overlay
reacts to a given workload.
- - Simulating algorithms with one of the legacy interfaces: :ref:`MSG
- for distributed algorithms <MSG_doc>` (in :ref:`C <MSG_doc>` or
- :ref:`Java <Java_doc>`) and SimDAG for
- centralized algorithms (in C). SimGrid was founded in 1998, and
- many interfaces were proposed along the way. MSG (introduced
- around 2002) and SimDag (introduced before 2000), are still present
- in SimGrid. They do not evolve anymore, but given their popularity,
- they will not be removed until at least 2020. That being said, our
- goal is to make S4U so useful that these legacy APIs become useless
- and obsolete.
- - We are currently working on the ability to modify any existing
+ - A prototypal tool is intended to allow the modification of any existing
application so that it can run on top of SimGrid. This project,
called `Remote-SimGrid
<https://framagit.org/simgrid/remote-simgrid>`_, is somewhat
of any legacy application, with absolutely no modification. We call it
SimOS, even if it will not become usable before several years of
additional work.
