I am thinking now about how to progress my MapReduce library that is in the Boost SandBox. I have completed the single-machine implementation; it's performance is comparable to other libraries such as Phoenix (http://mapreduce.stanford.edu) and has been tested by a few people on this list. There has, however, been little interest in the library so far from Boost users/developers which surprises me. I don't know if that is because of the single-machine limitation and people don't see any value that MR can bring to multi-threaded programming? So where do I go next with the library? Options that I see are: 1. Complete the documentation and submit the current library to Boost for a formal review. I'm not clear there is sufficient interest, though. 2. Continue to develop the library in the sandbox to multi-machine implementation and work towards submitting that for formal review. Is there interest for this? 3. Accept that Boost is not an appropriate forum for a MapReduce library and find an alternative community to develop the library. Looking at the download figures from the Vault, there has been a reasonable number of downloads; Of course there is no way to tell the number of people looking at the sandbox implementation. Perhaps the library has some silent interest? Please let me know your thoughts.
