LF Fortran 95

TRYBLK.F90

TRYBLK.F90 is a Fortran source file you can build with LF95. It tries a range of blocksizes and displays an elapsed time for I/O operations with each bocksize. You can use the results to determine an optimum value for your PC to specify in your programs. Note that a particular blocksize may not perform as well on other PC's.
