Also,the checkpointing slows things down somewhat... I suggest you get stuck with my 0.51 binaries.

That's odd. I know that happens when it cannot test some numbers due to various conditions. Can you give some examples?

what about this:

(can say only for WIN-version)

the residues written with lower letters a-f instead of hex-looking A-F

I can easily change that. Does that cause an issue?

no, not an issue but all other programs display 0123456789ABCDEF hex this way and it's easier (i think so, long computer related, self programming poeple) for such eyes, and HEX is in capital letters!

Not sure if this is an issue with all builds:

If I scroll up in a DOS box to see previous output it start overwriting it instead of continuing at the bottom.

That is more likely a DOS issue than a phrot issue. If you use CygWin and run it from the command prompt, it works correctly.

phrot 0.61 is released. I inadvertently added a bug that prevents phrot from restarting correct. That has been fixed. There was also an issue that prevented it from detecting certain ABC file formats correctly. That has been fixed. A Windows build (requiring CygWin) can be found here.

The two things I would like to do with phrot in a future release are:

1) Support BOINC. That should be relatively easy.
2) Create a networked version, which theoretically could be used to in place of LLRNet. If anyone is interested in helping me out, send me a PM and we can work out some details. I have a fairly good idea as to how I want it to work, but I want to avoid the complexity of BOINC.

Yay! This would be a HUGE benefit for projects such as Conjectures 'R Us and Sierpinski/Riesel Base 5.

I tried using Phrot 0.61 under Linux on some Sierpinski base 23 numbers today, and it still won't resume properly from phrot.ini, despite the fact that it saves the phrot.ini and phrot.ckpt files without a problem.

In the meantime, I'll crunch the range with v0.52 since that seems to be working stably for me.

The value for LastLine= should refer to the line of the last completed test. The line number might have been incorrect in previous releases (i.e. off by one). To get to 0.61, delete the ini file, then delete lines corresponding to all completed tests from you input file, then restart phrot. It will continue from the checkpointed test.

Well, this range had actually been run with 0.61 from the beginning--so, any and all checkpoint/phrot.ini files had been saved by 0.61.

If I remember correctly, yes, the LastLine= value was a little off in 0.61, but in 0.52 it's right on.
