  1. Martin says:

    It seems like a 1000x speed up is worth much more than $500K. Just the amount of hardware cost saved is tremendous. And $500K is only about 1-2 man years of work, when accounting for contractor overhead, profit, etc. (Assuming the labor rate multiple for a contractor is still about 2.9). But, if someone can and is willing to do it, that would be awesome. But I suspect they could sell the intellectual property to someone else for a lot more.

  2. Martin says:

    BTW, a business idea for Pointwise. Pointwise could investigate the feasibility of gathering some investors together to offer a $500K prize for a 10x speedup over the state of the art (whatever that is) as long as Pointwise is required as the means to generate the grid. And, of course, Pointwise/Investors get a portion of the profits from licensing the CFD code. I’m guessing that $500K over a few years would probably be easy to recoup.

  3. John Chawner says:

    Hi Martin. Thanks for the feedback. I hadn’t seen the biz angle before. Also, you should share your comment with NASA. What are you thinking? $2 million?

    • Martin says:

      The implications of a 1000x speed up are tremendous, so I’m thinking the worth of that IP is at least a few hundred million dollars. However, protecting that IP may be challenging, so that number may be high. I don’t know. Anyway, IMO, the worth of that top prize should be at least $10M. And that would be an absolute bargain for the government.

  4. Martin says:

    I Googled the cost of a supercomputer, and came up with this. I used this, in part, to justify my numbers. (6-7million just for powering Sequoia per year. And that does not include maintenance and administration. And, $100M-$250M for designing and building.)
