Numerical Methods in Finance and Economics by Paolo Brandimarte

MPI Thread

<t>Quote As for PS3 clusters, I think in the short time this will be popular, but word from researchers in the industry is that ultimately the cell is going to lose out to GPU. Well, the PS3 itself only gives you 128 MB of XDR ram per chip that is accessible to the user, so using a PS3 cluster can b...

APL, J, and K

For a interesting commentary on APL, I recommend that you read a couple of sections out of Richard Bookstaber's "A Demon of Our Own Design: Markets, Hedge Funds, and the Perils of Financial Innovation". The section entitled the "The APL Cult" would probably interest you.

Three years from now: can you predict the Software Landscape in anno 2018?

<t>It's been just over two years since this thread lost its momentum, and I was wondering if people still hold the same opinions on the nature of future software development given changes in hardware that are here now or coming (multicore, gpu's, fpga's, special purpose processors-i.e. Cell BE, acce...

<r>QuoteOriginally posted by: CuchulainnWith C++ - if that is the language you want - you can use OpenMP and MPI, which are free.
