[Gnuplotfortran-discuss] Fastest use of gnuplot

[Peter Leigh-J. <Pet...@in...>]

Hi Guys,
 
I often have to process very large data files, perhaps 30Mbytes in x,y 32 bit straight BINARY format and I have always used Fortran and gnuplot in a Windows box of some sort.
I am getting this week a new windows box with a couple of 8 core Opterons, 32 GB RAM, some 6GB/s SAS RAID 0 15k rpm drives and a 512 core GTX580 CUDA/GPU video card.
 
Have you considered (simply!) recompiling a "fast/big" gnuplot to 64 bit Win 7 and letting it read binary files of say 1E7 x,y data points as fast as possible using CPU/GPU/CUDA cores?
Multi cores is becoming the name of the game and a few of us in the World just have to look at very big data sets.
 
Of course, looking at the BIG sets lets us look at the minutiae subsequently.  I like you set xrange[ ... ] apparently only working in RAM and not re-reading the whole data set out of disk in version 4.4!
 
I should add that whilst I do much Fortran programming and modeling in the simplest/fastest sense, I do not do GUI's in the FTN code: takes too much effort and time, hence gnuplot to simply look at the results!
