  1. Effects of compilation flags / AVX instruction-set?

    For, e.g., the Rodina CFD benchmark, it would be interesting to see the difference between the generic "vanilla -O3" optimized executables and SandyBridge/IvyBridge "O3 AVX" optimized executables for...
  2. Except for scientific codes, where the AVX2...

    Except for scientific codes, where the AVX2 instruction set offers the potential of doubling the floating-point performance for codes doing LINPACK-style (array AX+B) computations. I would expect...
  3. compiler settings?

    For at least some of these benchmarks, compiler settings should make a substantial difference: it would be interesting to see the comparison between SSE4 vs AVX vs AVX2 enabled executables for...
  4. xrandr --panning or xorg.conf virtual

    The last time I checked (the nouveau driver from OpenSuse 2012.2) I could not get either

    xrandr --fb <mxn> --panning <mxn>...

    or

    xorg.conf/Section "Screen"/Subsection...

    bogus crtc_bounds() calls, xrandr --panning and xorg.conf virtual

    Are they ever going to fix all of those bogus crtc_bounds() calls that basically destroy
    one's ability to use "xrandr --fb=.. --panning" or virtual displays larger than the
    physical display in...

    No.

    A general command-line-scanner library is a general facility, that provides what is in fact a "little language". And one thing that (should have been) thouroughly learned from the Fortran...
  8. Autoconf is another problem...

    And my default test-builds on my base system run for four different compilers. That's 12 different build-directories, that autoconf doesn't know how to manage.
  9. Autoconf is another problem...

    Autoconf makes it difficult to maintain multiple simultaneous binary types. For a given source base, I want at least the following:

    Optimized
    Debug
    Optimized profiling

    and I want it to be...

    I am a scientific programmer, not a compiler writer. I do contribute to Open Source software: I'm the chief maintainer and the primary author (>99%) for a set of open source environmental modeling...
