[QUOTE=msft;257597]Hi ,ET_

Thank you,[/QUOTE]

What are the basic differences between cudaLucas and MacLucasFFTW?

From what I remember they only changed in the name of the executable...

Yes, same code.
But PrimeNet can not recognize same code.
Never use MacLucasFFTW.

I see...

Thanks! :smile:

Somebody can make 64 builds CUDALucas.1.2 ([url]http://mersenneforum.org/showpost.php?p=253480&postcount=431[/url]) and upload to forum?

For Windows.

I'm using CUDALucas 1.2 and I'm pretty happy with it.

If I had to tell, I miss the timestamp information after each 10000 iterations (something like xx.xxx msec/iter, ot ETA: xx.yy.zz) I had on MacLucasFFTW...

msft, Jean Penne' just released llrp Version 3.8.0, a portable version of LLR 3.8.4 using FFTW.
It uses a portable adaptation of George Woltman's gwnum library, but, at
the contrary of llrpi which is stand alone, it uses Matteo Frigo and Steven G. Johnson's FFTW library, Version 3.2.2
The main advantage of using this library is that a power of two FFT length
is no more required, which may sometimes gain a factor of two in speed!

There is a post in the SOFTWARE section, if you are interested in it.

Hi ,ET_
Thank you for the information.

I'm going to be away from my computer for several weeks. Two questions:

1) What is the best way to restart the program after a reboot due to a power failure? Windows 7 machine.

2) How do I make sure it doesn't retest exponents on a restart? I have several exponents queued up using a worktodo.bat file. However, on a reboot it will retest the exponent on the first line of the worktodo.bat file.

On linux, I use the following in a bash script. Reads input from worktodo.txt (one number per line), and for each input, checks to see if there is already a result output into mersarch.txt. Might there be something similar you could do in a .bat?

[CODE]while read i; do
if grep -q "M( ${i} )" mersarch.txt; then
echo ${i} is already done.
else
${NICE} CUDALucas $i
fi
done < worktodo.txt[/CODE]
