<BLOCKQUOTE class=cite cite="" type="cite"><FONT size=2>What I'm proposing
is:<BR></FONT> <BR><FONT size=2>- Define a standard set of FT error
handlers for a defined set of policies (see, e.g., Bronis' proposal aired at
the telecon: nothing, local MPI calls, pt2pt w/o affected process, coll w/o
affected process, pt2pt w/ affected process, coll w/ affected process)<BR>-
Provide a prototype implementation of those handlers in terms of the proposed
API<BR>- Allow implementors to provide error handlers that do not use this
API, if they find a better way of fixing particular FT issues up<BR>- Allow
users to create their own error handlers using the proposed API, to which end
the API should be functional inside an error
handler</FONT></BLOCKQUOTE><BR>Alexander, just to clarify, are you suggesting
that we have two APIs, one low-level API and another API that consists of
easy-to-use error handlers?<BR><BR><BR>Greg Bronevetsky<BR>Post-Doctoral
