=title=
Tolerating Stop Failures in Distributed Maple
=abstract=
Earlier we introduced some fault tolerance mechanisms to the
parallel computer algebra system Distributed Maple such that
a session may tolerate the failure of
nodes and connections without overall failure.
We have extended this fault tolerance by some advanced
mechanisms. The first is the reconnection of a node after
a connection failure such that a session does not deadlock.
The second mechanism is the restarting of a node
after a failure such that the session does not fail. The
third mechanism is the change of the root node such that a session
may tolerate also the failure of the root without overall failure.
