Hello, I'm afraid I'm not going to be as much help as I'd like with this; I don't have access to a machine where I can recreate this issue, and I am not an MPI expert. Are you able to confirm that the cause is not one of the two reasons it lists, e.g. is `mpd` running and was it started with a console (-n) option? If this is the case, I'm afraid I can't think of another reason why such a specific error would be given. If mpd is not running, or was started incorrectly, this might be an issue your systems administrator will need to address; I'm afraid I can't say for certain as I'm unfamiliar with mpd. I'm very sorry that I can't be more help, -Ward > Hi, > > I would like to build netCDF for I/O parallel support, I follow the > instruction on > https://www.unidata.ucar.edu/software/netcdf/docs/build_parallel.html, > but come across the following problem. > > ============================================= > netCDF 4.3.3.1: nc_test4/test-suite.log > ============================================= > > # TOTAL: 56 > # PASS: 55 > # SKIP: 0 > # XFAIL: 0 > # FAIL: 1 > # XPASS: 0 > # ERROR: 0 > > .. contents:: :depth: 2 > > FAIL: run_par_test.sh > ===================== > > > Testing MPI parallel I/O without netCDF... > mpiexec_xx-virtual-machine: cannot connect to local mpd > (/tmp/mpd2.console_xx); possible causes: > 1. no mpd is running on this host > 2. an mpd is running but was started without a "console" (-n option) > > > I have checked above two points, but have no idea to solve this yet, could > you please help me with this?
