It uses the gwnum library. gwnum detects the CPU and automatically uses the optimal code for it. --Mark Sun, 25 Oct 2009 13:24:29 GMT Di Maria Giovanni http://tech.groups.yahoo.com/group/openpfgw/message/2063 http://tech.groups.yahoo.com/group/openpfgw/message/2063 Hi Can somebody compile pfgw for AMD processor? Thank you. Giovanni Sat, 17 Oct 2009 16:51:38 GMT Mark Rodenkirch http://tech.groups.yahoo.com/group/openpfgw/message/2062 http://tech.groups.yahoo.com/group/openpfgw/message/2062 ... 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 Sat, 17 Oct 2009 14:25:04 GMT djbroadhurst http://tech.groups.yahoo.com/group/openpfgw/message/2061 http://tech.groups.yahoo.com/group/openpfgw/message/2061 ... This test breaks GWNUM 25.13: $ pfgw -t -q"Phi(3,8^6353)/73" PFGW Version 20090928.x86_Dev (Beta 'caveat utilitor') [GWNUM 25.13] Detected in MAXERR>0.45 Tue, 13 Oct 2009 21:46:35 GMT Mark Rodenkirch http://tech.groups.yahoo.com/group/openpfgw/message/2060 http://tech.groups.yahoo.com/group/openpfgw/message/2060 As promised, the linux version of 3.2.3 can be found here: http://openpfgw.svn.sourceforge.net/viewvc/openpfgw/pfgw_linux_3.2.3.zip?view=log --Mark Sat, 10 Oct 2009 15:57:06 GMT Mark Rodenkirch http://tech.groups.yahoo.com/group/openpfgw/message/2059 http://tech.groups.yahoo.com/group/openpfgw/message/2059 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 Sat, 10 Oct 2009 14:58:10 GMT Mark Rodenkirch http://tech.groups.yahoo.com/group/openpfgw/message/2058 http://tech.groups.yahoo.com/group/openpfgw/message/2058 I have verified that the SUMOUT issues are addressed in 3.2.3.

I will test these with that version. --Mark Fri, 09 Oct 2009 17:55:28 GMT darren_bedwell http://tech.groups.yahoo.com/group/openpfgw/message/2056 http://tech.groups.yahoo.com/group/openpfgw/message/2056 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 Fri, 09 Oct 2009 17:28:27 GMT darren_bedwell http://tech.groups.yahoo.com/group/openpfgw/message/2055 http://tech.groups.yahoo.com/group/openpfgw/message/2055 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).

I hope to make a Windows build available this weekend. Once I do, I'll let Steven know and he can build you a linux executable. --Mark Wed, 07 Oct 2009 01:48:49 GMT djbroadhurst http://tech.groups.yahoo.com/group/openpfgw/message/2053 http://tech.groups.yahoo.com/group/openpfgw/message/2053 ... 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.

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 Mon, 05 Oct 2009 16:18:51 GMT mgrogue@... http://tech.groups.yahoo.com/group/openpfgw/message/2051 http://tech.groups.yahoo.com/group/openpfgw/message/2051 ... I have added that after calling gwset_square_carefully_count().

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
