RPLOADGO(2) LAM REMOTE LIBRARY RPLOADGO(2)NAMErploadgo - 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 search‐
ing 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 dae‐
mon) is full.
