Preparation for Recitation 20
Read the paper Manageability,
Availability and Performance in Porcupine: A Highly Scalable Internet
Mail Service by Yasushi Saito, Brian Bershad and Hank Levy.
Answer the following question, and turn in your answer via the
submission page, before the start of your recitation:
How do Porcupine nodes recover the 256-entry user map after a crash?
What configurations might require a user map that contains more than
256 entries? Do you think the user map should still be soft state
in those configurations?
