Regarding Segmantation fault error during ADCIRC+SWAN run

Postby murty.iitd on Thu Oct 27, 2011 3:08 am

Hi all,

I am PLN Murty, doing PhD at IIT Delhi, India. I am trying to implement coupled ADCIRC - SWAN model. I have compiled the code as given in the mannual. While I am executing the model , I am getting error like Segmentation Fault.

I am using the command mpirun -np 32 ./padcswan for running in parallel.

When I give the above command, the following message are displayed which ended with an error (Segmantation fault) message...

I have pasted that below.

SWAN is preparing computation

TIME STEP = 100 ITERATIONS = 11 TIME = 0.10000000E+03
ELMAX = 0.6104E-06 AT NODE 3218 SPEEDMAX = 0.1139E-04 AT NODE 3449 ON MYPROC = 0
TIME STEP = 200 ITERATIONS = 10 TIME = 0.20000000E+03
ELMAX = 0.3473E-05 AT NODE 3358 SPEEDMAX = 0.5079E-04 AT NODE 3449 ON MYPROC = 0
TIME STEP = 300 ITERATIONS = 9 TIME = 0.30000000E+03
ELMAX = 0.9315E-05 AT NODE 3358 SPEEDMAX = 0.1184E-03 AT NODE 3449 ON MYPROC = 0
TIME STEP = 400 ITERATIONS = 9 TIME = 0.40000000E+03
ELMAX = 0.1684E-04 AT NODE 3392 SPEEDMAX = 0.2131E-03 AT NODE 3449 ON MYPROC = 0
TIME STEP = 500 ITERATIONS = 9 TIME = 0.50000000E+03
ELMAX = 0.2491E-04 AT NODE 3392 SPEEDMAX = 0.3344E-03 AT NODE 3449 ON MYPROC = 0
TIME STEP = 600 ITERATIONS = 9 TIME = 0.60000000E+03
ELMAX = 0.3818E-04 AT NODE 8403 SPEEDMAX = 0.4822E-03 AT NODE 3449 ON MYPROC = 0
forrtl: severe (174): SIGSEGV, segmentation fault occurred
rank 16 in job 24 ajaymeru.cas.iitd.ernet.in_46714 caused collective abort of all ranks
exit status of rank 16: return code 174

Can anyone kindly suggest me how to overcome this problem.

Thanks in advance.
