NAME

rploadgo − Load and execute a LAM program on a remote node.

C SYNOPSIS

#include <kio.h>

int rploadgo (int srcnode, int destnode, char *filename, int flags, char **argv, int *pid, int *idx);

FORTRAN SYNOPSIS

subroutine RPLDGO (srcnode, destnode, filename, flags, pid, idx, ierr)

integer srcnode, destnode, flags, pid, idx, ierr
character filename*(*)

ARGUMENTS

	srcnode		where program is stored
	destnode		where new process will be created
	filename		program file
	flags		runtime flags passed to new process
	argv		null-terminated array of strings to be passed as command-line arguments to the new process
	pid		new process identifier (output)
	idx		new process index (output)

DESCRIPTION

If the source and destination nodes are identical, the program is not transferred and the process is created with rpcreate(2). Otherwise the program is transferred with rload(2), stored in /tmp on the destination node, and created with rpgo(2).

If the source node is the local node, the program is located by searching the directories defined in the PATH environment variable of the caller. Otherwise, the PATH variable of the remote LAM daemon is used. Usually, the only difference is in how the "." directory is resolved. On the local node it is the current working directory of the calling process. On a remote node it is the user’s home directory.

Current Working Directory
By default, rploadgo() will propagate the caller’s current working directory to the created process if target node is the local node. This is accomplished by passing the RTF_CWD runtime flag to rpgo(2) or rpcreate(2). A remote process will assume the remote home directory as its current working directory. This behaviour can be changed by the RTF_APPWD runtime flag.

Runtime Flags
Runtimes flags are defined in <kio.h> (<NET.h> for Fortran) and can be added together in any combination.

	RTF_WAIT		The new process will send a message to the calling process, received by rpwait(2), when it exits. This flag is used if the parent is interested in the exit code of the child process. Failure to call rpwait(2) at some point after using this flag will leave stray messages with weird events in buffers on the caller’s node.
	RTF_TRACE		Enable tracing for the new process.
	RTF_APPWD		The current working directory will be the location of the executable program.

ERRORS

	ENOPDESCRIPTORS		The remote process descriptor table is full.
	ENOFLDESCRIPTORS		The table of strorage blocks (kept by the flat daemon) is full.
