Here is a C program based on my twingaps program (itself based on fastsieve by TOS). A Windows binary is included as well as a batch file for running it.
In order to save the results you should redirect the output into a text file, e.g.:
Code:
run.bat >> logfile.txt
See the batch file for the parameter settings.
BTW.: It runs pretty fast. Up to 1 billion (1e9) in just 1 second...
And a list of largest gaps found up to 1e9:
