Now that I have finally access to Cheyenne I wanted to test some codes on it that have successfully run on Yellowstone. The first is using cam5_4_108 and running a standard CAM5 case (FAMIPC5) at f19_f19 resolution. The model compiles successfully on Cheyenne but crashes after the 2nd time step giving this error: 6: SNICAR ERROR: snow grain radius of 0 out of bounds.6: NSTEP= 26: flg_snw_ice= 16: column: 5917 level: 0 snl(c)= -16: lat= 42.6315789473683 lon= 97.50000000000006: h2osno(c)= 0.7783605336451006: calling getglobalwrite with decomp_index= 5917 and clmlevel= column6: local column index = 59175: local column index = 49696: global column index = 378625: global column index = 378466: global landunit index = 123266: global gridcell index = 37366: gridcell longitude = 97.50000000000006: gridcell latitude = 42.63157894736836: column type = 16: landunit type = 16: ENDRUN:6: ERROR in SnowSnicarMod.F90 at line 426 When I go through the lnd log files they are identical up to this point: ** cheyenne ** Attempting to read global land mask from /glade/p/cesmdata/cseg/inputdata/share/domains/domain.lnd.fv1.9x2.5_gx1v6.09020 6.nc (GETFIL): attempting to find local file domain.lnd.fv1.9x2.5_gx1v6.090206.nc (GETFIL): using /glade/p/cesmdata/cseg/inputdata/share/domains/domain.lnd.fv1.9x2.5_gx1v6.09020 6.nc lat/lon grid flag (isgrid2d) is T ncd_inqvid: variable LANDMASK is not on dataset decomp precompute numg,nclumps,seglen1,avg_seglen,nsegspc= 5663 72 F 2.247222 35.00000 Surface Grid Characteristics longitude points = 144 latitude points = 96 total number of land gridcells = 5663 Decomposition Characteristics clumps per process = 1 gsMap Characteristics lnd gsmap glo num of segs = 2708 ** yellowstone ** Attempting to read global land mask from /glade/p/cesmdata/cseg/inputdata/share/domains/domain.lnd.fv1.9x2.5_gx1v6.09020 6.nc (GETFIL): attempting to find local file domain.lnd.fv1.9x2.5_gx1v6.090206.nc (GETFIL): using /glade/p/cesmdata/cseg/inputdata/share/domains/domain.lnd.fv1.9x2.5_gx1v6.09020 6.nc lat/lon grid flag (isgrid2d) is T ncd_inqvid: variable LANDMASK is not on dataset decomp precompute numg,nclumps,seglen1,avg_seglen,nsegspc= 5663 384 T 1.000000 14.74740 Surface Grid Characteristics longitude points = 144 latitude points = 96 total number of land gridcells = 5663 Decomposition Characteristics clumps per process = 2 gsMap Characteristics lnd gsmap glo num of segs = 5663 Why would cause some of those decomp precompute variables like nclumps, etc. to be different?
