I've got a 4.4c/l , Agner Fog's says the thruput on 64 bit mul is 4c/l , but in another section it says you can issue one every cycle , if the latter section means 32bit then , 4c/l could be right ( I say could not would as consider the K8) , I expect I can do a bit better than 4.4c/l , but who knows.A lot of the speed comes from reducing the overhead in mul_basecase. It quite a wide cpu , I would expect the combined functions(like addlsh1) to make a real difference on it. > Supposedly you can do 4 or even 5 instructions at once with instruction > fusion. > > Bill. > > On 05/03/2009, ja...@njkfrudils.plus.com <ja...@njkfrudils.plus.com> wrote: > > the functions missed out were > > addadd > > addsub > > addlsh > > sublsh > > the 2% due to them is not bad , considering they were written for an AMD > > chip. > > The other new functions like redc,sumdiff are used unconditionally > > > > I think sumdiff is still in the optional section of configure , must > > change this some time , it's confusing , but it doesn't hurt. > > > > On Thursday 05 March 2009 18:42:20 Bill Hart wrote: > >> If the mpirbench is about 10300 on sage.math then it worked. > >> > >> I can't check it till I'm home. > >> > >> Bill. > >> > >> On 05/03/2009, ja...@njkfrudils.plus.com <ja...@njkfrudils.plus.com> > >> > >> wrote: > >> > commited , and I think I should be > >> > > >> > On Thursday 05 March 2009 17:50:59 ja...@njkfrudils.plus.com wrote: > >> >> Done it , just cant commit at the moment !!! > >> >> > >> >> On Thursday 05 March 2009 17:43:04 Bill Hart wrote: > >> >> > Damnit I am still not getting anything in config.h.
