Another bug, this time in the -od option. Notice that the decimal expansion is even!

Code:

 ./pfgw64 -od -q666*2^10000000+1

That isn't the entirety of the decimal expansion. I'll investigate.

Something wrong with copy/paste

Two at the power of 10 millions should have 3 millions digits. Or am I out of the subject?

Well spotted that person, my semi-mistake!

If I output to a file the answer looks possible and the correct length, it's the output to the console (shown correctly in the post) that is completely screwy.

rogue · 2011-10-28, 13:36

I think it is due to an inherent limit in output written to stderr on OS X. The buffering of the output is done by the OS, not pfgw. pfgw on Windows outputs the entire string.

That sounds possible as the output appears to truncate after printing the correct initial part of the string.
Not a problem now I know it happens and I can't do a quick look without sending the result to a file.

Hi,
Is there a way to set affinity for each instance of pfgw64 / win64pfgw running under windows (other than using task manager)?

Not at this time.

Try this tool for setting affinity (option "-a").

Rename the pfgw*.EXE (like pfgw1.exe, pfgw2,exe, ... ), so you don't have to use the PID but the program-name (easier in scripts).

I believe you can also do it using the "start" command.
