head -c `stat -c%s <n-path>` o-path | diff - <n-path>
should work. Where o-path is the path to the old output, and n-path is the path to the new.
Seriously though, I have no idea what you are requesting.
If you're still running a plot on the GPU, could you then try running one of the CPU plotters with the same parameters (address, nonce range, stagger size) for a few minutes and check that they match in the part created by the CPU plotter? Say the directory containing the GPU plotter output (the "plots" directory") is <GPU-path>, and the path to the CPU output is <CPU-path>. Could you then run this command in a terminal and report back its output? If they match, there should be no output.
head -c `stat -c%s <GPU-path>` <CPU-path> | diff - <CPU-path>
Gotcha.
I'll take a look into testing this tomorrow. Once the GPU plot I have going currently finishes.
I didn't forget... Plot file just finished.
I ran your test with some smaller plot files:
cdmedia/twig/Burst_Coin_21/~~Linux~~/Plot_Generator
./plot 11111222223333344444 0 2000 1000 4
cdmedia/twig/Burst_Coin_21/~~Linux~~/GPU_Plotter_v2.0.0/bin
./gpuPlotGenerator.exe generate 0 0media/twig/Burst_Coin_21/test/GPU 11111222223333344444 0 2000 1000 64 1024
head -c `stat -c%smedia/twig/Burst_Coin_21/test/GPU/11111222223333344444_0_2000_1000`media/twig/Burst_Coin_21/test/CPU/11111222223333344444_0_2000_1000 | diff -media/twig/Burst_Coin_21/test/CPU/11111222223333344444_0_2000_1000
After issuing the last command, it just returns to a prompt... no additional output. I assume this means the plot files match.
(also I am mining and finding shares from the GPU plot as well)
Warning: to the AMD owners, the 14.4 catalyst driver cause a major bug. The generated files are corrupted. I will investigate on this problem. In the meantime, I recommend you to switch back your driver to the 13.12 version.
My plots appear to be fine (on Linux) generated with the 14.4 catalyst driver, as compared to the same plot generated with the CPU
I'll test out v2.0.1 and see if there are any changes.

That's a good news, even if I will have to investigate more on this part ^^
For those who already generated some files with the plotter, to make sure the generation is successful, do the following :
Generate a file with the same parameters as your full plot file (address + offset + stagger) but with a noncesNumber of 1.
The generated file has to match with the first bytes of your full file.
