I know now one reason for the missed primes. I have seen an issue with my laptop that leads to "low on memory" warnings. This is happening in pfgw and causes pfgw to terminate before it processes...

The major change in this new release is that it supports ABCD files as the input file format in addition to newpgen format. The ABCD format is about one-fourth the size of the newpgen format which...

If each 1G range has about 6500 remaining k after being tested to n=25000, you should be good.

Although I haven't proven it to myself yet, I'm fairly certain certain that the problem is with resuming from a checkpoint, specifically when the phase has to be broken into sub-phases. For example,...

Possibly. IMO, if you run pl_remain up to 10000 and find no new primes, then the likelihood of an issue is extremely small. I've run some tests and see no patterns that tell me where the problem is.

I ran into an issue with srbsieve. When it breaks up large ranges for PRP testing it is skipping some of those ranges. I don't how that is happening, but I'm looking into it.

This means that if...

nsieve is only for base 2, so it isn't too helpful for this project.

The first test I ran shows non-matching output on my Mac. I don't think this is a miscompile. It is either bad assembly code or the prime sieve is missing primes.

It appears to be a miscompile on Windows with mingw. The outputs on my Mac are different and appear to be correct, although I haven't run any comparisons.

It isn't my code. I'm trying to find contact information for Ken Brazier as he wrote it although I might be able to debug without his help.

I just ran one test. nsieve and newpgen do not produce the same outputs. I assume that nsieve must have some bugs in it. That will take time to resolve.

I recommend building with this:

g++ -O3 -m64 nsieve64.cpp -lstdc++ -o nsieve

It is currently slower than fermfact, but I found one optimization that seems to make it faster for multiple n, but...

I just discovered that Ken Brazier has a program called nsieve64. This can work like newpgen, but is 64-bit. As it is source, it can be compiled on other platforms. It claims to be faster than...

I see why it isn't outputting the remaining k's. It builds a string with the information but doesn't dump it to the screen.

I don't see a problem in the code. Did you stop and restart the range at some point? Can you e-mail me the input files you used?

Use the latest srbsieve. If pl_remain.tmp never decreases in size, then there is a problem, but it could be due to you using a buggy version of srbsieve.

Not a test a test of your ability to perceive my mistakes though. :ouch2: It was a test of my ability to zip the correct file.
