ADVANCED MENU
-------------
You should not need to use the Advanced menu. This menu choice is
provided only for those who are curious. To avoid confusion for
novice users, most of the choices in the Advanced menu have been grayed.
Please read this section if you want to know what the Advanced menu choices
do. To turn on the Advanced menu, use the Advanced Password dialog box
and enter a value of 9876. Also note that many of the menu choices are
grayed while testing is in progress. Choose Test/Stop to activate
these menu choices.
The Test choice can be used to run a Lucas-Lehmer test on one Mersenne
number. Enter the Mersenne number's exponent - this must be a prime
number between 5 and 79300000.
The Time choice can be used to see how long each iteration of a Lucas-Lehmer
test will take on your computer and how long it will take to test a
given exponent. For example, if you want to know how long a Lucas-Lehmer
test will take to test the exponent 876543, choose Advanced/Time and
enter 876543 for 100 iterations.
The ECM choice lets you factor Mersenne numbers using the
Elliptic Curve Method of factoring. Select a few exponents and bounds
to factor from the http://www.mersenne.org/ecm.htm web pages.
Note: You do not reserve exponents to work on, several people can
do ECM factoring on the same exponent. The program uses a random
number generator to select elliptic curves to test. You must email
results to me at woltman@alum.mit.edu - primenet does not support ECM
factoring. WARNING: ECM does not adhere to the memory limits specified
in the Options / CPU dialog box. ECM requires a minimum of 192 times
the FFT size. Thus, ECM factoring of F20 which uses a 64K FFT will use
a minimum of 192 * 64K or 12MB of memory. You can also edit the
worktodo.ini file directly. For example:
ECM=751,3000000,0,100,0,0,0,0
The first value is the exponent. The second value is bound #1. The
third value is bound #2 - leave it as zero. The fourth value is the
number of curves to test. The fifth value is no longer used.
The sixth value is the specific curve to test - it is only used in
debugging. The seventh value is 0 for 2^N-1 factoring, 1 for 2^N+1
factoring. The eighth value is no longer used.
The P-1 choice lets you factor Mersenne numbers using the P-1 method of
factoring. There is presently no web site which tells you how much
P-1 factoring has already been done on exponents. You can also edit
the worktodo.ini file directly. For example:
Pminus1=751001,1000000,0,0,0
The first value is the exponent. The second value is bound #1. The
third value is bound #2. The fourth value is 0 for 2^N-1 factoring,
1 for 2^N+1 factoring. The fifth value is no longer used.
Round off checking. This option will slow the program down by about 15%.
This option displays the smallest and largest "convolution error". The
convolution error must be less than 0.49 or the results will be incorrect.
There really is no good reason to turn this option on.
The Priority menu is used to adjust the priority prime95 runs at.
You should not need to change this. You might raise the priority
if you (or your coworker) just cannot live without a screen
saver (bad idea), or if you are running some ill-behaved program
that is using CPU cycles for no good reason.
The Manual Communication menu choice should only be used if the
automatic detection of an Internet connection is not working for you.
Using this option means you have to remember to communicate with the
server every week or two (by using this same menu choice).
The Unreserve Exponent choice lets you tell the server to unreserve
an exponent you have been assigned. You might do this if a second computer
you had been running GIMPS on died or if you had been assigned an exponent
of one work type (such as a first-time-test) and now you have switched to
another work type (such as 10,000,000 digit numbers). Any work you have
done on the unreserved exponent will be lost.
The Quit GIMPS menu choice is used when you no longer want this computer
to work on the GIMPS project. You may rejoin at a later date.
If you are a PrimeNet user your unfinished work will be returned to the
server. If you are a manual user, you need to send me email containing
your results.txt file and a note saying you are quitting.
Listen, here's the thing. If you can't spot the sucker in the first half hour at the table, then you ARE the sucker.
