Ghassan, my appologies.  I've read your article.  What I wrote was about 
optimal basic blocks scheduling.  I've not seen articles about optimal 
scheduling beyond basic blocks.  So most probably your article is really 
the first published work about optimal scheduling of superblocks.

My appologies again.
