... Thanks, George. The linux build has not changed since August 18. It would be great to have a completely order-independent linux build, with Mark's latest...
... I have patched the one piece of code that I had already mentioned. Steven can grab at any time and produce a build if he wants, but I would prefer that he...
... I can also break gwnum with polcyclo(13): $ pfgw -tc -q"Phi(13,2^2749)/8191" Error occuring in PFGW at Tue Sep 29 00:41:16 2009 Expr = Phi(13,2^2749)/8191 ...
... That would be helpful, please, if (and only if) it is compiled with George's mt19937.c file. Then we will be left with a clearly reproducible brokenness of...
... Not so. The switch -a1 will avoid the errors that I have reported. Videlicet: $ pfgw -tc -a1 -q"Phi(13,2^2749)/8191" ... Yet without -a1, version 3.2.2...
... That is of no account, since mt19937.c would be vitiated by the indubitable order dependence on bases in the version of August 18. Conversely, a new linux...
... I will not make -a1 mandatory. The better option is to have PFGW tell users to use the -a switch for primality tests that fail due to rounding and sumout...
... A fortiori, this recent Windoze build: http://openpfgw.svn.sourceforge.net/viewvc/openpfgw/pfgw_win_3.2.3_20090928.zip should be now free of *all*...
... I will remove this today. I have not announced it officially and as long as this other issue exists in PFGW or as long as I don't improve the message when...
I have modified PFGW to do the following when a roundoff/sumout/mismatched sums error occurs during a primality test: pfgw -t -q"Phi(82730,2)" Primality...
... I should like to have a version free of all order dependence ... Then the remaining issues would be free of order dependence. But you are the boss, Mark....
... Just to be clear that we aren't talking Apples and Dells, there are two separate order dependence issues. The first is the random number generator used in...
Hi Mark, ... As Phil speculated, we are dealing with a number that has a nasty bit pattern that magnifies FFT rounding errors. There seems to be three...
... I have added that after calling gwset_square_carefully_count(). Here is the new output using -a1 and -tc: Primality testing Phi(82730,2) [N-1/N+1,...
... As Phil correctly speculated, these errors were due to non-random bit patterns that the FFTs hate. I've upgraded the gwnum code to detect many of these...
... Phil correctly post-dicted my entirely deliberate intent :-) ... Thank ye kindly, Sir! ... I shall do my best to oblige, when a new linux build appears. ...
I found an interesting dark corner. For all of these numbers, PFGW 3.2.2 gives an error (unless -a1 is used, in which case they come back as composite). Same...
This seems like a bug, not a feature. Something about this number makes WinPFGW 3.2.2 err when the -a1 option is used. -qR(3021,160809)*10+1 -f -a1 Error...
I have release PFGW 3.2.3. Here is a list of changes: - Fix an issue with -t when using an input file, PFGW would not reuse bases, thus re-ordering the file...
... That's OK from my perspective, as long as PFGW suggests that you use the -a1 or -a2 switch. It would be much worse if the result of the test were given as...
