intel processor diagnostic tool freeze math

On reference results and we can confirm the code works as it is supposed to. After some hours of debugging and fixing errors, the code was tested Up until now, nothing too special nor rocket science involved.

So our version of the code reconstructs data sets of sizes like 2048x2048x512. ART is a technique used to reconstruct the data received from a computer tomograph machine to get If you're not familiar with ART, just a simple explanation what it does.

I can't currently post / link to any sourceĬode as this is ongoing research that cannot be published. So the code executes some FFTs and consumes quite some time to finish calculation. The program is doing sort of modified ART on quite large input sets of data. Besides using this machine to develop CUDA Kernels and stuff, I recently tested a pure C program.

I'm currently running Ubuntu 15.04 64bit Desktop version, latest updates and kernel stuff installed. Operating system & program code in question Doing some research on this problem, there might be a possible bug in the INTEL Haswell architecture as well as in the current Skylake Generation.īefore writing about the possible bug, let me give you an overview of the hardware used, the program code and the problem itself. During the last days I observed a behaviour of my new workstation I couldn't explain.
