<div>Hai everybody <BR>&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;Iam using AIX Loadleveler3.1 for checkpointing my simple serial application.The problem is while generating ckeckpoint file.It generates ckpt file name with extension .err,here(stp.ckpt.err).when restarted_from_ckpt is set to yes in job command file and run the job ,the node simply remove the job from the queue and&nbsp;even could not get output file. <BR>&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I am posting my job command file and application here.Please&nbsp;reply if anybody knows what is the problem for not generating correct ckpt file&nbsp;,how to debug the problem.Tnx in advance <BR>&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;My job command file <BR>&nbsp;&nbsp;&nbsp; <BR>&nbsp;&nbsp;# For First.c <BR># @ job_type = serial
