[sage-devel] Re: coercion issue?
Regarding compilation with debug, zn_poly is passed the flag -DNEBUG for a couple of files, instead of -DNDEBUG. This is a sloppy typo on my part. Originally I think I took the output from the zn_poly configure script, but in the latest version there were some new files, and I guess I added the targets by hand to the FLINT makefile. At any rate, that is not the cause of our problems, and I will fix it in the next version of FLINT. As for something not being reduced before being passed to zn_poly, it is likely that someone assumed FLINT reduces coefficients mod p before doing anything with them, which it does not. I met at least one such person. It would be a performance issue to do this at any level. Instead, FLINT assumes all polynomials it is passed have reduced coefficients and it guarantees too return polynomials which respect this, except for I think one function (zmod_poly_add_nored I think) which would be specifically documented as not doing so. Sorry none of this actually helps find the bug. It is still possible of course that zn_poly is actually being passed garbage by FLINT, and that garbage just happens to not be reduced. At some point in Martin's wrapper of zmod_poly in Sage, there was an option you could switch on to compare the output from FLINT with that of Pari. Thus helped us track down the specific polynomial computation which caused the issue last time. Bill.

I think what's actually happening is that the underlying FLINT zmod_poly object is not getting coefficients reduced into [0, 10]. This causes other problems indirectly (e.g. #5817). I can't quite trace why this is happening. Any ideas? There is a also a performance issue. The following is in sage 3.4.2: sage: R.x = PolynomialRing(Integers(11^6)) sage: S.y = PolynomialRing(Integers(11^3)) sage: f = R([ZZ.random_element(11^6) for _ in range(100)]) sage: time g = f * f CPU times: user 0.96 s, sys: 0.01 s, total: 0.97 s Wall time: 0.96 s sage: f = S(f) sage: time g = f * f CPU times: user 0.93 s, sys: 0.00 s, total: 0.93 s Wall time: 0.93 s sage: f = S([ZZ.random_element(11^3) for _ in range(100)]) sage: time g = f * f CPU times: user 0.55 s, sys: 0.00 s, total: 0.55 s Wall time: 0.55 s What appears to be happening is that FLINT is using kronecker substitution for the multiplication (packing polynomials into an integer and then multiplying the integers), but in the second multiplication above it is *not* reducing mod 11^3 before doing this. Even better evidence is the following: if I install flint 1.2.5 (as per trac #5817) I get: sage: R.x = PolynomialRing(Integers(11^6)) sage: S.y = PolynomialRing(Integers(11^3)) sage: f = R([ZZ.random_element(11^6) for _ in range(100)]) sage: f = S(f) sage: time g = f * f sage.bin: zn_poly/src/zn_poly.h:185: zn_mod_add_slim: Assertion `x mod-m y mod-m' failed. /home/dmharvey/5817/sage-3.4.2-new/local/bin/sage-sage: line 198: 16421 Aborted (core dumped) sage-ipython $@ -i This means two things: (1) zn_poly is getting compiled with debug assertions, which it shouldn't, since this is a major performance loss, and (2) some zn_poly routine is getting called on a polynomial with non-normalised coefficients. But I still don't know exactly where the non-normalisation is happening. david --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

No, gcc 4.4.0 works on multiple platforms. The issue the Arch people are seeing happens to cause problem on at least gcc 4.2.x - see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28671#c8 - and the correct thing to do is to not compile gcc with arch or march settings. I have fixed 95% of #2999-3001 in all spkgs which would all to inject flags like march into each spkg. Personally, I've never even used GCC 4.4.0, not even once.

Please try again.Trac is unstable right now for unknown reasons,
but I did setup a script so that if it doesn't respond for about 1-2
minutes, then it is autorestarted. Thus if you would have tried again
it would have worked shortly. Note that nobody is actually
working on fixing trac yet (I wish somebody would, since I likely
won't have time to for at least 2 more weeks). Anyway, this is now
trac #6163:
http://trac.sagemath.org/sage_trac/ticket/6163
By the way, I can replicate this problem on sage.math, and you're
right that it is caused by switching to pynac.

Sage 4.0 compiled cleanly from source on Fedora 8 x86_64 Linux, but
I get a
segfault with the following commands:
theta1,theta2=var('theta1,theta2')
g0=theta1
h0=g0.subs(theta1=1,theta2=0)
Various perturbations of this seem to work (ie, not subbing theta2,
using
t1,t2 as the variable names). I assume that this is a consequence
of the
pynac switch.
My version of gcc is gcc version 4.1.2 20070925 (Red Hat 4.1.2-33).
The
error message is:

Segmentation fault sage-ipython $@ -i
I would submit this to trac, but the trac server seems to be down at
the
moment.
FWIW, I can reproduce this on my system (Mac OS X, 10.5.7, Dual Quad
Xeon). I have a crash log, in
sage.math.washington.edu:logs/sage.bin.log
The failure also occurs with sage-4.0.rc2, but not with 3.4.2.

[sage-devel] coercion of polynomials with integer coefficients
Hello,
I would like to take a create a function that takes a polynomial over
the integers and returns its roots in ZZ mod p for p a prime. I want
to assume the polynomial is globally defined but the prime is the
argument.
Here is what I have in mind but can't quite get the types right.
x = var('x') #necessary?
poly=x^2+x+1
def myroots(p):
R=IntegerModRing(p)
RR.t=R[]
f=poly.substitute(x=t) #coercion here
return f.roots(R)
How do I convert or coerce poly to be in R?
Thanks in advance!
Walter Kehowski

[sage-devel] Re: coercion issue?
This is now http://sagetrac.org/sage_trac/ticket/6168. david On May 30, 12:03 pm, Bill Hart goodwillh...@googlemail.com wrote: Regarding compilation with debug, zn_poly is passed the flag -DNEBUG for a couple of files, instead of -DNDEBUG. This is a sloppy typo on my part. Originally I think I took the output from the zn_poly configure script, but in the latest version there were some new files, and I guess I added the targets by hand to the FLINT makefile. At any rate, that is not the cause of our problems, and I will fix it in the next version of FLINT. As for something not being reduced before being passed to zn_poly, it is likely that someone assumed FLINT reduces coefficients mod p before doing anything with them, which it does not. I met at least one such person. It would be a performance issue to do this at any level. Instead, FLINT assumes all polynomials it is passed have reduced coefficients and it guarantees too return polynomials which respect this, except for I think one function (zmod_poly_add_nored I think) which would be specifically documented as not doing so. Sorry none of this actually helps find the bug. It is still possible of course that zn_poly is actually being passed garbage by FLINT, and that garbage just happens to not be reduced. At some point in Martin's wrapper of zmod_poly in Sage, there was an option you could switch on to compare the output from FLINT with that of Pari. Thus helped us track down the specific polynomial computation which caused the issue last time. Bill.

Would appreciate help from people familiar with FLINT wrapper and/or coercion system. sage: R.x = PolynomialRing(Integers(121)) sage: S.y = PolynomialRing(Integers(11)) sage: S(50*x) 6*y sage: R(S(50*x)) 50*x # !! I think what's actually happening is that the underlying FLINT zmod_poly object is not getting coefficients reduced into [0, 10]. This causes other problems indirectly (e.g. #5817). I can't quite trace why this is happening. Any ideas? There is a also a performance issue. The following is in sage 3.4.2: sage: R.x = PolynomialRing(Integers(11^6)) sage: S.y = PolynomialRing(Integers(11^3)) sage: f = R([ZZ.random_element(11^6) for _ in range(100)]) sage: time g = f * f CPU times: user 0.96 s, sys: 0.01 s, total: 0.97 s Wall time: 0.96 s sage: f = S(f) sage: time g = f * f CPU times: user 0.93 s, sys: 0.00 s, total: 0.93 s Wall time: 0.93 s sage: f = S([ZZ.random_element(11^3) for _ in range(100)]) sage: time g = f * f CPU times: user 0.55 s, sys: 0.00 s, total: 0.55 s Wall time: 0.55 s What appears to be happening is that FLINT is using kronecker substitution for the multiplication (packing polynomials into an integer and then multiplying the integers), but in the second multiplication above it is *not* reducing mod 11^3 before doing this. Even better evidence is the following: if I install flint 1.2.5 (as per trac #5817) I get: sage: R.x = PolynomialRing(Integers(11^6)) sage: S.y = PolynomialRing(Integers(11^3)) sage: f = R([ZZ.random_element(11^6) for _ in range(100)]) sage: f = S(f) sage: time g = f * f sage.bin: zn_poly/src/zn_poly.h:185: zn_mod_add_slim: Assertion `x mod-m y mod-m' failed. /home/dmharvey/5817/sage-3.4.2-new/local/bin/sage-sage: line 198: 16421 Aborted (core dumped) sage-ipython $@ -i This means two things: (1) zn_poly is getting compiled with debug assertions, which it shouldn't, since this is a major performance loss, and (2) some zn_poly routine is getting called on a polynomial with non-normalised coefficients. But I still don't know exactly where the non-normalisation is happening. david --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
