    Fortran 9x is likeable, even if it's still somewhat limited. I'd like to see Fortran 2003 become fully supported by major compilers in the near future -- but what I can't wait for is the co-array features of Fortran 2008, so that I can ditch MPI once and for all!

    Fortran 77 is the reason why people laugh at Fortran.

    It could well be. I've a Belkin wired+wireless router between my two computers and the cable modem, and it tends to die when I transfer large file between the wired computer and the wireless one. This indicates poor stability, so I guess it could be the same sort of thing with BT.

    Nope, it's 64KiB/s; I like to set upload speeds to half my upstream bandwidth.

    If your router can't keep up, limit the number of connections, transmission can probably do that.

    I don't see such option in Transmission. It's not known for being rich-featured though, so maybe I should try a different client.

    Myelin was discovered in 1854, and I don't think it's been measured in humans for too long. Any study in this direction will be pure statistical noise, and even if there were tons of data it would be biased by the improvement in measuring techniques.

    This is similar to the claims that have been made in the past decade that men are becoming less fertile.

    And this crap about it being a resource hog is BS. If you're running all the bells and whistles, I got news for you folks, of course it's going to be a comparative pig - geeze. Turn off Aero if you got a low end machine or buy the machine with Home instead of Ultimate - god!

    While I disagree with the general Vista bashing, it is not difficult to confirm that Vista is a lot slower than XP. I've got both installed in VirtualBox. XP boots in 10-15 seconds, Vista in 1-1.5 minutes. That's the time to get to the desktop; responsiveness comes 5 seconds later for XP and 1 minute later for Vista. Audio stutters on Vista but not on XP. Same with video. Etc.

    I like most of the changes in Vista. From big things like UAC to small ones like the naming of C:\Users. But one can't deny it's a damn heavy OS.

  24. Re:Naive question... on $208 Million Petascale Computer Gets Green Light · · Score: 1

    In the case of QMC the parallelization is done with respect to the population of walkers. In the most common implementation of diffusion Monte Carlo, this population is allowed to vary, so the population on different nodes at any given time may be different, preventing 100% efficiency.

    Then, the main problem in diffusion Monte Carlo is the need to set a global "reference energy" after every move of the walkers, which enforces synchronization across nodes and requires frequent communication. What to do about this reference energy is something that is being actively researched --having independent "reference energies" introduces a so-called "population-control bias", but it may be possible to correct for this (or not).

    Another issue is that one may not want to increase the walker population as the number of nodes increases, since it may not give any advantage (excess precision), but instead to share the computational load of calculating things for each walker across several nodes.

    This is enough to keep the QMC community entertained until this machine goes online, and probably for a while afterwards too..

    Yes, I know this is probably a very naive question, but has anyone here actually had the privilege of working on one of these things? I mean, what do they actually use this for?

    The one application I know this computer is going to run is quantum Monte Carlo, which is an electronic-structure method. QMC is intrinsically parallel due to its stochastic nature, but the degree of parallelism involved here requires further breakdown of the algorithm. There are quite a few research groups putting effort into this.

    Other applications, if I am not mistaken, are also meant to be highly parallelizable, possibly nearing the boundary of embarrasingly parallel tasks. This is probably to make sure that the resource is used to its full extent.
