  5. Re:Faster than the nVidia GTX TITAN for $400 less on AMD's Radeon R9 290X Launched, Faster Than GeForce GTX 780 For Roughly $100 Less · · Score: 1

    I should be more precise on the context...
    We are mainly doing FFTs and Linear algebra in both single and double precisions. To give a little bit more details about the problem : we run the same code on multiple GPUs at the same time (each instance of the program has its own GPU and is not communicating with the other processes). It appears that, after a random number of iterations (it might be 1K, 10K or 100K), a kernel from CuFFT, or CuBLAS, or my own gets stuck and the program is killed by the watchdog of the driver.
    If it was a bug with the programs, the bug should happen for all GPUs (Titans, K20, C2070, 580s) and in fixed conditions (not at a random iteration, as each iteration does not have any different memory access than the previous one, no memory allocation, just values changing). But in the current conditions, it works well on all the K20, C2070 and 580 and sometime on the Titan too. Also, the programs were fully mem-checked and are rather simple (pure GPGPU computation). If it was a problem with the driver or the motherboard all computations should failed at some point which is not the case as sometime the program will work, even on the Titans. I also tried a large number of drivers in the 310-325 range, the 325 seems to give more stable run than the previous ones, but I still have crashes.

    What I cannot exclude : some (random) bad sync/timing/data link between motherboard (Supermicro) and the cards or some bit flip because of the card temperature near the memory modules (although the setup runs in a server room with a custom cooling system and show no temperature difference to other external benchmarks) or some remaining driver bug.

    You're lucky then... We replaced our cluster of 580s by Titans and these things keep crashing for no apparent reason (about 2/3 of the cards will randomly hang up on computation are run fine on the remaining cards)...

  7. Turn on the light, I can't click! on New Goggles Offer Minority Report-Style Interface With Heads-Up Display · · Score: 2

    So basically, the depth camera uses longitudinal chromatic aberration (the red green and blue colors are not in focus for the same distances). So it needs to have your finger well lighted at any time...
    I see no problem with that at all...

  8. Re:Corrective lenses adaptation? on Improved Image Quality For HMDs Like Oculus Rift · · Score: 1

    My bad, the cornea is no the eye lens, shame on me...

  9. Re:Corrective lenses adaptation? on Improved Image Quality For HMDs Like Oculus Rift · · Score: 1

    For the first thought, it is extremely hard (~impossible, depending on your specifications) to make a good quality optics with few elements that are (almost) free from distortions, chromatic aberration and aberrations (to keep it simple, blur) at the same time.

    For the second, it might not be possible. The problem of our eyes is that they are imaging a perfect point not into a point but a small blur. The imaging quality is perfect when the size of this blur is kept minimal (more complicated in the facts, but this is a reasonable approach). This blur is due to the fact that rays going through a lens a different position do not experience the same delays in their path. If you want to correct for that you have to present a pre-corrected light wave to your cornea (eye lens) and the main problem is that this pre-correction cannot be achieved by a regular display which produces real images instead of complex imaging, where the phase is representing the delay of each point of this light wave (called wavefront).

  10. Re:"The chance of an impact will certainly drop"? on No, the Earth (almost Certainly) Won't Be Hit By an Asteroid In 2032 · · Score: 1

    pr(impact) = 1 - pr(miss)
    If pr(impact) decreases, it is equivalent to pr(miss) being increased (by the same amount).
    So if pr(impact) drops closer to 0, then pr(miss) increases closer to 1.

  12. Re:I dunno about you... on Extreme Complexity of Scientific Data Driving New Math Techniques · · Score: 2

    That is NOT the way to understand these sets of techniques. Candes, Tao and Donoho's works are basically about saying : what is the minimum number of measurements that I have to do to make sure that the reconstruction of the signal will be sufficient (for a given task), assuming that the signal has some known properties?

    Let's say you hear the sound of horseshoes while walking in a street, if I ask you what is the color of the coat of the animal, you won't probably start by saying "red" or "blue". This is because you know already some of the classical equine coats colors which means you technically need less information to find the real color.

    This technologies can also help for q signal corrupted by noise since the properties of the first might be, in some way, orthogonal to the last, leading to a clean removal.
