Hi,
I am trying to do an rsh and execute the same script on a distant unix computer.
The problem is that I need to get all the local variables of the distant computer to launch correctly my script.
I'm working on AIX 4.3.3
I try to execute .profile in the rsh but it seems not to be... (1 Reply)
Guys, how can I define global variables in sorlaris...cause I lose the values outside the scope.
Rite now wat I do is,I redirect variable value to a file n then get it back outside the function...:o....theres obviously a better way of doing this...I now this is a basic question....but please... (2 Replies)

I have a problem with 'while'
I am trying to set variables by 'while' and it is fine inside, but after completting the loop all changes are lost:

I do a ssh to remote host(A1) from local host(L1). I then ssh to another remote(A2) from A1.
When I do a who -m from A2, I see the "connected from" as "A1".
=> who -m

Hi ,
I am trying to find some files on a remote machine using the find command.
>ssh -q atukuri@remotehostname find /home/atukuri/ -name abc.txt
/home/atukuri/abc.txt
The above command works fine and lists the file, but if I want to do a long listing of files (ls -l) its not working . ... (2 Replies)
Hi, i'm trying to gather details from remote hosts and want them to be written to my local linux machine from where i'm using SSH. My command looks some thing like this
ssh -q remotehost 'bash -s' <command.txt

I have a number of files in the /tmp directory with PET-DOG in their name. I want to delete them, leaving only files with PET-CAT and PET-HORSE. I'd like to use the find command to locate those files (by using a variable) and then I'd like to delete them. However, I can't find a way to do this. I... (3 Replies)
I have googled this and found many solutions, but none of them are working for me. I am in a korn shell, most others reference bsh, maybe that is the issue? Anyway, all I am trying to do is use a variable I have declared in my main script in a remote shell I am running through ssh.
So I have a... (8 Replies)
Hi Folks,

mpi_alloc_mem
MPI_Alloc_mem(3OpenMPI)MPI_Alloc_mem(3OpenMPI)NAME
MPI_Alloc_mem - Allocates a specified memory segment.
SYNTAX C Syntax
#include <mpi.h>
int MPI_Alloc_mem(MPI_Aint size, MPI_Info info, void *baseptr)
Fortran Syntax (see FORTRAN NOTES)
INCLUDE 'mpif.h'
MPI_ALLOC_MEM(SIZE, INFO, BASEPTR, IERROR)
INTEGER INFO, IERROR
INTEGER(KIND=MPI_ADDRESS_KIND) SIZE, BASEPTR
C++ Syntax
#include <mpi.h>
void* MPI::Alloc_mem(MPI::Aint size, const MPI::Info& info)
INPUT PARAMETERS
size Size of memory segment in bytes (nonnegative integer).
info Info argument (handle).
OUTPUT PARAMETERS
baseptr Pointer to beginning of memory segment allocated.
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_Alloc_mem allocates size bytes of memory. The starting address of this memory is returned in the variable base.
FORTRAN NOTES
There is no portable FORTRAN 77 syntax for using MPI_Alloc_mem. There is no portable Fortran syntax for using pointers returned from
MPI_Alloc_mem. However, MPI_Alloc_mem can be used with Sun Fortran compilers.
From FORTRAN 77, you can use the following non-standard declarations for the SIZE and BASEPTR arguments:
INCLUDE "mpif.h"
INTEGER*MPI_ADDRESS_KIND SIZE, BASEPTR
From either FORTRAN 77 or Fortran 90, you can use "Cray pointers" for the BASEPTR argument. Cray pointers are described further in the For-
tran User's Guide and are supported by many Fortran compilers. For example,
INCLUDE "mpif.h"
REAL*4 A(100,100)
POINTER (BASEPTR, A)
INTEGER*MPI_ADDRESS_KIND SIZE
SIZE = 4 * 100 * 100
CALL MPI_ALLOC_MEM(SIZE,MPI_INFO_NULL,BASEPTR,IERR)
! use A
CALL MPI_FREE_MEM(A, IERR)
ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI:Exception object.
Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
