Fatal error in PMPI_Bcast: Invalid communicator, error stack:

I haven't seen this type of errors ever.
Please help me in this regard.

Please send me your namelist.input to take look.
By the way, did this error occur at the right beginning of the model run?
How did you compile the code?
 
Dear Sir,
Thank you for the reply.
I have this error only at 'wrf.exe', everything before that ran fine.
I have added the namelist file for you to see.
I used GFORTRAN and GCC for compilation.
Sincerely -
Saurav

I am not 100% sure whether this is the reason for the model crashing. Just for the purpose to narrow down the problem,
(1) please turn off the quilting option , i.e., please set
nio_tasks_per_group = 0,
nio_groups = 1,

(2) please set
start_year = 2018,
start_month = 10,
start_day = 21,
start_hour = 18,
start_minute = 00, 00, 00, 00, 00, 00,
start_second = 00, 00, 00, 00, 00, 00,
end_year = 2018,
end_month = 10,
end_day = 22,
end_hour = 00,

Then try again.
 
Hello,

PMPI_Bcast(1541): Invalid communicator error might be caused by incomplete network configuration. Take a look at your /etc/hosts file, you might miss a line like:

<ipaddress> <hostname.domain> <hostname>

If I remmeber correctly, ommiting that could cause PMPI_Bcast error.

Anyways, I will try both of them.
Thank you for the support.
