both METIS_PartGraphRecursive and METIS_PartGraphKway fail when npart = 1 in Fedora 37 and Fedora 39 (gcc 13.2.1).
METIS_PartGraphKway throws seg fault whereas METIS_PartGraphRecursive hangs up.
The following example code reproduces the issue:
#include <metis.h> #include <iostream> #include <vector> int main() { int nVertices = 6; int nEdges = 7; std::vector<int> xadj = {0, 2, 4, 6, 8, 10, 12}; std::vector<int> adjncy = {1, 2, 0, 2, 3, 1, 3, 4, 2, 4, 5, 3, 5}; int options[METIS_NOPTIONS]; METIS_SetDefaultOptions(options); std::vector<int> partition(nVertices); int nParts = 1; std::vector<int> objval(1); std::vector<int> part(nVertices); METIS_PartGraphRecursive(&nVertices, &nEdges, xadj.data(), adjncy.data(), NULL, NULL, NULL, &nParts, NULL, NULL, options, &objval[0], &part[0]); //METIS_PartGraphKway(&nVertices, &nEdges, xadj.data(), adjncy.data(), NULL, NULL, NULL, &nParts, NULL, NULL, options, &objval[0], &part[0]); std::cout << "Partitioning Result:" << std::endl; for (int i = 0; i < nVertices; ++i) { std::cout << "Node " << i+1 << " is in partition " << part[i] + 1 << std::endl; } return 0; }
this may be related to #67 ?
