Hi, I am a Phd Candidate and currently I am planning to implement an distributed extendible hashing, therefore I want to reference some implementation of SDDS. From the paper "Scalable Distributed Data Structures for High-Performance Databases" i know that you have the experiences of integrating the database with SDDS, and also from http://ceria.dauphine.fr/SDDS-2005/SDDS-2005.HTM I know that the source code is available upon request, that is the reason I wrote this email. Would you please tell me how to acquire the source code of SDDS? I am very grateful for that.
