Hi, Does anyone have an accessible reference to the OOPSLA paper "An efficient parallel heap compaction algorithm" by Abuaiadh, Ossia, Petrank, Silbershtein ....that is cited as a reference in the paper Xiao Feng points to below? All my google searches lead to the ACM Portal :-) Thanks, Rana On 10/27/06, Xiao-Feng Li <[EMAIL PROTECTED]> wrote: > > Hi, all, the plan for GCv5 parallel compaction is to apply the idea of > Compressor [1].
