I cannot accept something if you don't know if it missed some primes. The nature of this project requires virtually 100% accuracy. My suggestion is to redo the range.

The mod that you suggest is an excellent one that I'm sure we'd all like to see.

That's exactly what I intend to do.

BTW, I didn't expect you to mark the range complete to n=16500, but you can at least capture the primes.

OK thanks. I'll do that.

It's odd that an OS update would cause a program to not write to a specific file like that.

It may not be related, but I've noticed some odd behaviour with pfgw as well.
For R55, I'm running
Code:
pfgw.exe -f0 -l sr55p1.pfgw
and it's grinding through normally. However, it's not writing to pfgw.out periodically, only when I hit ctrl+C.

Windows XP, PFGW 3.3.6

Everything so far is composite according to the screen output.

There were issues with the 10.7.2 update for OS X Lion. They only affected some people. Apparently I was one of them. It manifested itself in various ways, such as hanging the Finder. I found a fix on-line, but it didn't fix all of the problems I had. I reverted back to 10.6 (a clean install). I'll re-install Lion in January.

Although you should upgrade to 3.5.7, you are the only person to report such a problem. Note that your problem is not the same as mine. Fortunately for that release all residues will also be echoed to the screen.

Since I won't fix issues with 3.3.6 I suggest you upgrade to 3.5.7 (or wait for 3.6.0) and keep an eye on it. If it continues to happen, then let me know.

OK, I'm going ahead and showing it complete to n=16.5K but I put an asterisk on the reservations page with a reference to a comment that n=10K-16.5K needs to be doublechecked.

If you're going to sieve, you might as well take to n=25000.
