Hi there,I am setting up CESM on a Los Alamos National Lab machine ('Wolf') in support of a SciDac project (Bette Otto-Bliesner, PI), and am currently playing with PE layout to maximize performance on this machine.However, when I look at the timing files of successfully completed run steps, they only say:$ cat cesm_timing_stats.150703-004208 ***** GLOBAL STATISTICS ( 630 MPI TASKS) ***** and I get an error in the sterr file that is thrown from getTiming2: WARNING getTiming2: 1 nprocs - running in mpiserial mode so no additional timing to be reported , exiting I am wondering if there is an obvious place to look, to figure out why only 1 processor (apparently) is being used for this?For reference I have attached the env*xml files from one such run (in .tgz)Thanks!
