i would like to map 1GB (possibly more) of in-memory tables
to another node via
the memory channel, so that when modifications are made to node A's
memory they appear automagically on node B, where a simple read only
portion of the application resides.
if i remember well, currently memchan is restricted to 512Mbytes...
is it possible?

As I understand it, the 512 mb feature never got implemented - the max is 128 mb. The code that wrote the data structure would have to be very carefully implemented, because MC only supports longword aligned writes. Also the MC error checking protocol would have to be followed (writer will have to do synchs after the write completes to insure there were no errors). Finally, keep in mind that a handful of 8k pages are stolen by the MC board for acces to internal registers, etc. and the MC software primatives also steal pages for its internal use.
