[MITgcm-support] Error while using both MPI and MNC packages

[Miroslaw Andrejczuk]

You need eedata file (in the directory where you run the model) containing:

# Example "eedata" file
# Lines beginning "#" are comments
# nTx - No. threads per process in X
# nTy - No. threads per process in Y
 &EEPARMS
 nTx=1,
 nTy=1,
 usingMPI =.TRUE.,
 /
# Note: Some systems use & as the
# namelist terminator. Other systems
# use a / character (as shown here).

@ Martin : I have now compiled as suggested by you "

genmake2 -mpi [more options]" :- in the code.




The next hurdle i face is at :

(i have kept the configuration same as given in the previous mail)

[dell at localhost input]$ mpirun -np 24 ./mitgcmuv > test2

STOP ABNORMAL END: PROGRAM MAIN    (24 times)


My "STDERR.0000" list the following errors:

(PID.TID 0000.0001) *** ERROR *** EESET_PARMS: Error reading parameter file "eedata"

(PID.TID 0000.0001) *** ERROR *** EEDIE: earlier error in multi-proc/thread setting

and my "STDOUT.0000" ends at

Please help me out.

Hello MITgcm users,

I am trying to use both multi processors (MPI) and NedCDF (MNC) packages at the same time.
In code my configuration is :
 "SIZE.h"
     &           sNx =  65,
     &           sNy =  45,
     &           OLx =   2,
     &           OLy =   2,
     &           nSx =   1,
     &           nSy =   1,
     &           nPx =   6,
     &           nPy =   4,
     &           Nx  = sNx*nSx*nPx,
     &           Ny  = sNy*nSy*nPy,
     &           Nr  =  23)

"packages.conf"

oceanic
gfd
exf
timeave
#mdsio
mnc
obcs

In "input" folder. The configuration is
"data.pkg"
# Packages
 &PACKAGES
 useOBCS=.TRUE.,
 useEXF=.TRUE.,
 useMNC=.TRUE.,
 &

 "eedata"
 # Example "eedata" file  for multi-threaded test
#   (copy "eedata.mth" to "eedata" to use it)
# Lines beginning "#" are comments
# nTx - No. threads per process in X
# nTy - No. threads per process in Y
 &EEPARMS
 nTx=1,
 nTy=1,
 useMPI=.TRUE.,
 &

"data.mnc"

# Example "data.mnc" file
# Lines beginning "#" are comments
 &MNC_01
# mnc_echo_gvtypes=.FALSE.,
# mnc_use_indir=.FALSE.,
 mnc_use_outdir=.TRUE.,
 mnc_outdir_str='mnc_test_',

#monitor_mnc=.FALSE.,
#timeave_mnc=.FALSE.,
#snapshot_mnc=.FALSE.,
#pickup_read_mnc=.FALSE.,
#pickup_write_mnc=.FALSE.,
 &


I use 24 number of processors . This is the message i get while running the model.

[dell at localhost input]$ mpirun -np 24 ./mitgcmuv > test
EEBOOT_MINIMAL: No. of procs=     1 not equal to nPx*nPy=    24
EEBOOT_MINIMAL: No. of procs=     1 not equal to nPx*nPy=    24
EEDIE: earlier error in multi-proc/thread setting
PROGRAM MAIN: ends with fatal Error
STOP ABNORMAL END: PROGRAM MAIN
(and this error is repeated for 24 times).

Please do provide me some suggestions/solutions.

Thanking all in advance
