Dear Dr. Banicescu We append a referee report on your paper C462: Experiences from Integrating Algorithmic and Systemic Load Balancing Strategies We would be happy to publish your paper if you addressed the changes suggested by the referee. I think this is quite easy! Please include a discussion of your changes and how they answer the referee in your resubmittal. If this is persuasive, we can publish your paper without further refereeing. I thank you for your interest in Concurrency.Practice and Experience and apologize for not replying earlier.

I have a few minor comments: o The use of the word systemic - I would advise that the authors to explain their usage of the word at the beginning of the paper. o Page 4, paragraph 2, prepending "in the above mentioned" twice appears a clumsy style. I would prefer something like "presented in the survey [1]". o Page 4, paragraph 2, you mention "a distributed architecture design" twice in this paragraph. You should explain what you mean by this. o Page 4, paragraph 2, sentence starting "Hector is designed to…" add plural to monitor. o Page 4, paragraph 3, perhaps remove "the" before MPICH. o Page 5, paragraph 3, change "certain size amount of" to "certain sized amounts of work" o Page 7, section 3.1, change "In Hector paradigm" to "In the Hector paradigm". o Page 7, section 3.1, change "don't" to "does not" o Page 9, section 3.2, add details about network technology connecting the cluster together. o Page 13, paragraph 2, Question, why does the MA separate threads handling this message queues? o Page 14, section 3.2.2, add "a" "does not result in a cost increase" o Page 16, section 4, Add discussion of how Hectiling would be affected my a heterogeneous platform, such as a PC cluster connected via various bandwidth interconnects. I would like to see a fuller discussion of the cost of task migration and its affects on performance of Hectiling. o Page 16, section 4, please add some words on how the authors see the Hectiling paradigm being generalized to support other applications which could benefit from this integrated load balancing strategy.
