GPUMD output is buffered by 4096 bytes #212

Hello, When I run program like gpumd < gpumd_in.txt | tee gpumd.out text appears on screen only when 4096 characters of output was produced. When I do not redirect to file, output appears normally at same time. Please make output unbuffered - described behaviour is not convenient to keep what is going on with calculation.

Thanks for reporting this. It is expected behavior and I will consider improving it at some point.
