Hi,
I am trying to use libhmetis.a library in cygwin. I tried hmetis-1.5-linux one but have not been successful. My error message says
"undefined reference to `HMETIS_PartRecursive'"
Could you post a library for cygwin or can I get the code so that I can compile myself?
Thanks |
Alex

Sorry, but hmetis's source code is not being distributed. |

Hi,
I am writing a c++ wrapper for the hmetis
functions using the library libhmetis.a
and would appreciate any pointers.
I've declared the library functions as:
extern void HMETIS_PartKway (int nvtxs, int nhedges, int *vwgts, int *eptr, int *eind, int *hewgts, int nparts, int ubfactor, int *options, int *part, int *edgecut);
extern void HMETIS_PartRecursive(int nvtxs, int nhedges, int *vwgts, int *eptr, int *eind, int *hewgts, int nparts, int ubfactor, int *options, int *part, int *edgecut);
and in my Makefile I am using pkg-confg and
have:
EXCERPT
g++ -L. -g -shared -fPIC ... `pkg-config --libs metis` -o libfcmpluskit.so
I am getting an "undefined symbol"
when I try to load the library.
Thanks,
Mark

Mark,
Which symbol is undefined? g++ should also report that along with the "undefined symbol" error. |

Hey Mark and Alex,
Try doing this
extern "C"
{
extern void HMETIS_PartKway (arguments list);
extern void HMETIS_PartRecursive(arguments list);
}
best,
Pranav |

Thanks Pranav.
I tried that and it worked. |

Hello,
I'm trying to implement the CHAMELEON algorithm and I have some doubts. Can somebody help me?
The doubts are:
- In phase II of the algorithm I have to connect the sub-graphs to calculate the clossness and the inter-connectivity. My doubt is how to connect two sub-graphs? Which objects of the two sub-graphs I have to connect?
- In phase II I have to merge sub-clusters and I have a doubt in the second alternative (RI(Ci,Cj)*RC(Ci,Cj)^alpha, pag. 11 of the paper about CHAMELEON). When does the merging of the sub-clusters stop? How to calculate the weight of the edges? Is the inverse of the distance beetween two points?
- I download the hMETIS package for the win32 plataform. I found all the files mentioned in the README file but I've encountered a possible problem. The file states that there should be available a libhmetis.a library. All we found was libhmetis.lib. I tried to include it into my C++ program but without success. Could you tell me what the difference is? How could I include the library (.lib) into my C++ program?
Please, somebody help me. I would like to have/implement the CHAMELEON algoritm because I need to.
Kind regards,
Jorge Duarte |

Hi,
I am trying to download hmetis-1.5-WIN32 but have not uncompress successfully. My error message says
”ZIP file have been destroyed"
Could you post a hmetis-1.5-WIN32 ?
Thanks |

Graph partioning for threads
I am interested in graph partioning for
user level to kernel level to global
threads.
Does anyone have any experience with Metis
in partioning workloads for threads?

Has anyone found a function in hmetis that point to the hyperedges that were cut?
Thanks a bunch! |

Hi,
Is there a way to use hmetis library on cygwin?
I tried linking from both windows and linux versions. Both gave error messages.
Thank you.
