Hi all,
after a while, I reactivated my cluster and I realized that I get the following error while running snappyHexMesh in parallel: Code:
cfd@OpenFOAM:~/OpenFOAM/cfd-dev/run/Columbia/detailedCFDAnalysis$ mpirun -np 20 snappyHexMesh -parallel **************************************************************************** * hwloc 1.11.2 has encountered what looks like an error from the operating system. * * L3 (cpuset 0x000003f0) intersects with NUMANode (P#0 cpuset 0x0000003f) without inclusion! * Error occurred in topology.c line 1046 * * The following FAQ entry in the hwloc documentation may help: * What should I do when hwloc reports "operating system" warnings? * Otherwise please report this error message to the hwloc user's mailing list, * along with the output+tarball generated by the hwloc-gather-topology script. **************************************************************************** /*---------------------------------------------------------------------------*\ ========= | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox \\ / O peration | Website: https://openfoam.org \\ / A nd | Version: dev \\/ M anipulation | \*---------------------------------------------------------------------------*/ Build : dev-adea51c53ccb Exec : snappyHexMesh -parallel Date : Dec 18 2018 Time : 21:49:53 Host : "OpenFOAM" PID : 2091 I/O : uncollated Case : /home/cfd/OpenFOAM/cfd-dev/run/Gibraltar/detailedCFDAnalysis nProcs : 20 Slaves : 19 ( "OpenFOAM.2092" "OpenFOAM.2093" "OpenFOAM.2094" "OpenFOAM.2095" "OpenFOAM.2096" "OpenFOAM.2097" "OpenFOAM.2098" "OpenFOAM.2099" "OpenFOAM.2100" "OpenFOAM.2101" "OpenFOAM.2102" "OpenFOAM.2103" "OpenFOAM.2104" "OpenFOAM.2105" "OpenFOAM.2106" "OpenFOAM.2107" "OpenFOAM.2108" "OpenFOAM.2109" "OpenFOAM.2110" ) Pstream initialized with: floatTransfer : 0 nProcsSimpleSum : 0 commsType : nonBlocking polling iterations : 0 sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster (fileModificationSkew 10) allowSystemOperations : Allowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Any suggestion?
