On a VPS I tested my build of hwloc-2.9.2 by running lstopo: ./lstopo hwloc: Topology became empty, aborting! Segmentation fault
On a GCP n1-standard-2 a similar build (GCC 12.2 vs. 13.2) seemed to work: ./lstopo hwloc/nvml: Failed to initialize with nvmlInit(): Driver Not Loaded Machine (7430MB total) Package L#0 NUMANode L#0 (P#0 7430MB) L3 L#0 (45MB) + L2 L#0 (256KB) + L1d L#0 (32KB) + L1i L#0 (32KB) + Core L#0 PU L#0 (P#0) PU L#1 (P#1) HostBridge PCI 00:03.0 (Other) Block(Disk) "sda" PCI 00:04.0 (Ethernet) Net "ens4" PCI 00:05.0 (Other) What steps should I take to find the cause of the failure on the VPS? I suspect an OS issue because in the past my builds of OpenMPI worked.
