A Cluster Of Pocket PCs

Don Stratton writes "This is the coolest thing I have seen anyone do with a Pocket PC... ever! Well-known Pocket PC developers SPB Software House, located in Russia, have come up with a very interesting spin on computing clusters. The short version is they connected 12 Pocket PCs together in the first known 'supercomputer cluster' of its type and had it calculate the old '3n + 1' problem. It was just done for fun, and not intended to seriously compete with desktop computers, but it does point out some interesting possiblilities for the future of handhelds with wireless connectivity working in ad-hoc computing clusters."

      The answer to your question is really kind of interesting. I came across it while searching through some japanese documents at the university of Nagasaki.

      instead of taking the "multiple-serializing" approach you suggest, you begin by using the output of your first transform filter as a sort of "seed" to feed groups of parallel "second-tier" transform filters. Once you've done that, you can see how it is easy to fan those outputs out and iterate into third or fourth-tier (obviously, that's a LOT of pocket PC's!) transform filters. As the filters each work their way through seed data, they each begin to converge toward (notice i didn't say TO) a solution. You then use what the japanese called a "recompositing Reimann filter" to sort of sift your way from the multi-tiered parallel seed results back into a final solution.

      If you would like to prove this property, you will obviously need the principle of mathematical induction. You would start with the base case of saying that the property holds for 1, the first number in the series, or P(1) holds. This is easy--

      1 => 1*3 + 1 = 4 => 4/2 = 2 => 2/2 = 1 => ...

      So, we essentially have to show that each number resolves to 1. We incidentally have proved by construction that 1 will infinitely cycle. Next, we assume that the property holds for P(n). We want to show that the property will hold for P(n+1). This is the tricky part. I would start the proof by saying

      If P(n) is odd, the next number in the sequence will be 3n + 1. By definition, this number will resolve to 1. If P(n) is even, n/2 will also resolve to 1. Each of these numbers are added into the set A. Continue extrapolating numbers from these two values and add them to A.

      Similarly, if P(n+1) is odd, the next number in the sequence will be 3n + 4, if it's even, it will be (n + 1)/2. Both of these numbers will resolve to 1. Each of these numbers are added into to the set B. Continue extrapolating numbers from these two values and added them to B.

      When we find a common element in A and B, we will have proven the hypothesis.

    Back around 1997 my group built a cluster of laptops running MPI for kicks. We laughed at how small it was stacked so we talked about making things even smaller. We talked about getting a number of Palms together or some other such tiny form factor machines and selling "6-packs" of clustered computing power - even to the point of laughing about making flanisters to put them in or cardboard "beer-like" holdersr Of course, back then, the aggregate computing power of a "6-pack Cluster" was about equal to that of just a regular PC.
