Hi,
Thanks for ur replies...
I am trying to simulate the environment whatever has been discussed here using ssh.
I am facing following problem while using ssh. The same is explained below..
case1: ssh -f <machine_ip> <executable1> <arguments>
Here, arguments are listed in file and those wil be read during execution. In this scenario, the parallel execution works fine.
case2: ssh -f <machine_ip> <cp file1 file2> <executable2>
Here, the executable in 'case 2' won't take command line arguments as in case of 'case 1', i.e. executable wil always read input arguments from file with name "args".
so what i tried here is i have created multiple text files with different arguments, during ssh i tried to copy these text files to file "args" and tried to execute "executable 2". But i am receving an error saying "Cannot fork into background without a command to execute.".
Can anybody suggest me the solution for this???
Thanks,
