commands let you choose from among any of five I/O redirection alternatives (modes) that are explained in the next section.

The srun I/O options
The all argument redirects stdout and stderr from all job tasks to srun (and hence to the attached terminal), and broadcasts stdin from srun (the terminal) to all remote tasks. This is srun’s default behavior for handling I/O.
noneThe none argument redirects stdout and stderr from all job tasks to /dev/null (receives no I/O from any task) and sends no stdin to any task (closes stdin).
taskidThe taskid argument redirects to srun (and hence to the attached terminal) stdout and stderr from the single specified task whose relative ID is taskid, where the range for integer taskid starts at 0 (the first task) and runs through the total number of tasks in the current job step. This choice also redirects stdin from srun (the terminal) to this single specified task.
filenameThe filename argument redirects stdout or stderr from all job tasks into a single file called filename, or broadcasts stdin from that same file to all remote tasks, depending upon the I/O command.
