How to use Test > Continue button
 

Does anyone know how to make your prime95 stop then continue using the continue button on Test toolbar?

Um...not sure what about it you don't understand.
To stop, use Test > Stop.
To continue, use Test > Continue.

Note that if it appears as a continue button then it is already stopped.

my continue button's greyed out even if i stop the torture test. so i can't click continue.

You can't continue a torture test, you just start another one.

Then what's the continue button for?

When LL testing, trial factoring, P-1 factoring or ECM factoring, one can stop the work. Once work is stopped, one can "Continue" where they were stopped by using the "Continue" menu item.

When torture testing the important thing is stressing the CPU and the memory, if you stop a computation you can just start anew, since what the program does is computing some results and compare them to known results.

When doing real work you want the ultimate result of a test, you do not want to lose all the work done until the time you stopped.

Prime95 torture test features are not its primary function, LL testing Mersenne numbers and factoring numbers are.

you can combine a torture test with finding actual prime numbers. Just register and let the program run in the background ...

Not really. A torture test requires the actual results to be known, so you can compare your results to the actual results, while discovering new/unknown primes requires that the actual results are unknown.

No you also get hardware errors with a normal testing ...

Torture testing can detect errors much faster. You can have a LL result with no error code detected during initial testing, only to discover (weeks, months, or years later) that it is a bad result.

A good and useful way of doing a sort of torture testing is to perform a double check. If it matches the first result, we can be pretty sure the machine has been reliable. If it doesn´t, well, the original LL might be faulty in the first place, so, especially if our run was error free, we may perform another test on a different exponent, and only then, if we still have no matches, perform the torture test. The good thing about this is that we are using the clock cycles to perform some real work. Every time I put a new machine to work I always start by doing a couple of DCs, to be on the safe side.

Sure. OTOH, there is a reason the first screen gives you two options: "Join GIMPS" or "Just stress testing". Prime95 is famous in the OC community for its torture test capability. People aren't going to join GIMPS, and wait to complete a double check just to see if their m/c is stable.

I think the original question got lost in the shuffle, so I'm going to attempt my own answer.

Programming is hard, and that includes placing onscreen buttons. If you grey out buttons that can't be used, then it's probably less stress on the programmer than removing the button altogether every time it can't be used. Besides, if they removed the button, they'd either have to deal with the blank space or there'd be a new question,"Why the hell is there blank space in my Prime95 window?"

Hope that's helpful.
