| Post subject: | radical() question |
I'm trying to compute the radical of the Kummer variety in genus 3 (trigonal case). Radical() churns away for about 5 days, displaying lots of stuff with the "prot" option switched on, but then seems to stop outputting any indication of progress (it's been running about an extra week since then). However it is still burning up 100% of a processor and 75% of a 8GB memory. Is there any possibility it might complete successfully after all this time, or is it possible it has got into a loop? Chris ps: last few lines of prot output are product criterion:36 chain criterion:45 ..................+.+.+..++.+.++++++++-+-------+---------- vdim= 24 (1)..... |

Please send us your example (SINGULAR input). The example might be just too big. Maybe we can investigate and find another way to get a result. For the meaning of the output see the manual (entry option, and then prot). Frank |

I've now stopped it after another week: // ** Interrupt at cmd:`finduni` in line:' ideal F=finduni(I);//F[i] generates I intersected with K[var(i)]' abort command(a), continue(c) or quit Singular(q) ?q halt 2 sage: quit Note I'm running 3.1.1 in from Sage. Input file is http://www.ma.hw.ac.uk/~chris/k_34_sing.txt and output (before the stop above) at http://www.ma.hw.ac.uk/~chris/sing_34_op.txt many thanks, Chris |
