Hello, sorry to bother the list again.<br> I am trying to run adol-c together with IPOPT (upstream) and ColPack (downstream) in order to run an economic model.<br>I am now using ADOL-C 2.3.0 and ColPack 1.0.8 and I am taking the LuksanVlcek1_sparse as example for my model (from folder ADOL-C-2.3.0/ADOL-C/examples/additional_examples/ipopt/LuksanVlcek1_sparse).<br>
As suggested by <span name="Assefaw Gebremedhin" class="gD">Assefaw Gebremedhin</span> (ColPack, thank you) I slightly modified the code in order to run it several times placing in function generate_tapes() this->jacval=NULL and this->hessval=NULL instead of jacval=NULL.<br>
However this doesn't seems to be the cause of the problem, as I run valgrind with and without it and the mismatch errors are the same.<br>You can find the complete example with the modified source code and the valgrind output here:<br>
<a href="http://lobianco.org/temp/LuksanVlcek1_sparse_multiple_working/">http://lobianco.org/temp/LuksanVlcek1_sparse_multiple_working/</a><br>The title is "working" because... both the example code and my real-case model in Linux despite the mismatch errors they works. However as I moved to Windows I started to get a segfault on my real-case model depending on the amount of input data (number of variables in the model to optimise).<br>
And then I noticed that increasing HPOFF (defined in ADOL-C_sparseNLP.hpp) from 30 to 60 I was ok.<br><br>So, basically what is HPOFF ? is there a way to get it automatically size depending on the dimensions of the problem, so it never crash whatever the data ?<br>
Pierre, for bocop did you use the examples in the ADOL-C repository as starting point or did you develop your code from scratch ?<br><br>Thanks,<br> Antonello<br clear="all"><br>-- <br>Antonello Lobianco<br>INRA, Laboratoire d'Economie Forestière<br>
