  • Cloud Compute Resources

    From neillclift@gmail.com@21:1/5 to All on Fri May 6 06:22:37 2016
    Hi,
    This is an off the wall query about compute resources.
    I am currently trying to compute all addition chain lengths for targets
    <=2^35. A few years ago I did these calculations for targets <= 2^34.
    This is going to take me many, many months to do on my home hardware.
    I was wondering if any mathematics researchers use cloud compute
    services to do large calculations?
    I have no idea yet if costs are reasonable or constraints on the
    environment (memory etc) rule this out. I expect not as my memory
    constraints are about 4GB virtual and could be limited quite a bit
    further if needed.
    So I was looking to see if others have gone down this path.
    Thanks.
    Neill.

    Well I don't know about Cloud resources but their have been a few
    examples of using other's home computers en mass. The SETE(sp?) search
    of/for deep space signals and the searches for particular large primes
    come to mind. You might be able to use such a set up to address your
    problem - that is if the computation can be divided into assignable
    pieces and the result of those smaller pieces combined. Various
    problems
    do arise if too much data must be transmitted back and forth.

    Good luck with your project.

    My son buys many machine-months of processor power from Amazon for computer-science research.  He was pleased with how easy it was to set
    up, and I was impressed by how cheap he said it was.  I think I recall
    that the cost was pennies per processor-hour.
