I am trying to partition this particular graph:
http://www.cc.gatech.edu/~xu/out.graph
Both pmetis and kmeits work fine when I try to partition it into less than 6 parts. But pmetis would core dump when I try to partition it into 6 or more parts. kmetis would core dump when I try to partition it into 8 or more parts. (kmetis still works for 6 and 7 parts, though). Sigh, I'm getting frustrated with this. Can you take a look and let me know what is happening, and how I can fix it? A lot of thanks in advance. The platform I am running on is Linux 2.4.20-30.9smp. I used gcc to compile the metis package:
ferrari002:~/t/test$ gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --host=i386-redhat-linux
Thread model: posix
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

It seems that the graph has vertices with zero vertex weights as well as edges with zero weights as well. This is the problem, and the zero-weight vertices should be removed. Also, given the distribution of the vertex weights, it may not necessarily have a balanced k-way solution once k becomes large. |

I got this error message when using metis 4.0 (Windows version)
------------------------------------------------------------------------------
*** I detected an error in your input file ***
In the first line of the file, you specified that the graph contained
9383 edges. However, I only found 9383 edges in the file.
Please specify the correct number of edges in the first line of the file.
------------------------------------------------------------------------------
Any idea what is wrong? |
