Hello
I am trying to install fftw3.3.3 on an HPC system. The system has openmpi installed ( though we can choose between a variety of mpi distributions). However, while ./configure step of fftw, there is an error. The relevant section of the output is:
The command i used was:
I also installed mpich2 in my home folder and provided its path through MPICC variable (shown below) but i got the same error as above.
Kindly help as i'm stuck with this.

hi everyone,
I need fftw3 libraries (FFTW Installation on the MacOS) but I can't succeed in installing them on my Mac OSX.
I tried with "./configure make make install" procedure, fink and macports but my programs always ask me "fftw.h" files?
can you help me?
thank you!!

1st,I'm a newbie.
I've written a mpi program to realize the parallel computing and encounter many problems.
1. When the computing scale is small, that means the communication time is short, just needs few minutes, such as 14 minutes or less. The program runs well and finished the jog.

Hi all,
I write a simple MPI program to send a text message to another process. The code is below.
(test.c)
#include "mpi.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char* argv) {
int dest, noProcesses, processId;
MPI_Status status;

I am trying to install links2 with graphics support on snow leopard 10.6.8 (xcode installed). I have had the program running last year, also installed from source - but then I had installed some image libraries with mac ports and fink - cannot reproduce that setup. Plus I would like to not...

mpi_init_thread
MPI_Init_thread(3OpenMPI)MPI_Init_thread(3OpenMPI)NAME
MPI_Init_thread - Initializes the MPI execution environment
SYNTAX C Syntax
#include <mpi.h>
int MPI_Init_thread(int *argc, char ***argv,
int required, int *provided)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_INIT(REQUIRED, PROVIDED, IERROR)
INTEGER REQUIRED, PROVIDED, IERROR
C++ Syntax
#include <mpi.h>
int MPI::Init_thread(int& argc, char**& argv, int required)
int MPI::Init_thread(int required)
INPUT PARAMETERS
argc C/C++ only: Pointer to the number of arguments.
argv C/C++ only: Argument vector.
required Desired level of thread support (integer).
OUTPUT PARAMETERS
provided Available level of thread support (integer).
IERROR Fortran only: Error status (integer).
DESCRIPTION
This routine, or MPI_Init, must be called before any other MPI routine (apart from MPI_Initialized) is called. MPI can be initialized at
most once; subsequent calls to MPI_Init or MPI_Init_thread are erroneous.
MPI_Init_thread, as compared to MPI_Init, has a provision to request a certain level of thread support in required:
MPI_THREAD_SINGLE Only one thread will execute.
MPI_THREAD_FUNNELED If the process is multithreaded, only the thread that called MPI_Init_thread will make MPI calls.
MPI_THREAD_SERIALIZED If the process is multithreaded, only one thread will make MPI library calls at one time.
MPI_THREAD_MULTIPLE If the process is multithreaded, multiple threads may call MPI at once with no restrictions.
The level of thread support available to the program is set in
provided, except in C++, where it is the return value of the function. In Open MPI, the value is dependent on how the library was config-
ured and built. Note that there is no guarantee that provided will be greater than or equal to required.
All MPI programs must contain a call to MPI_Init or MPI_Init_thread. Open MPI accepts the C/C++ argc and argv arguments to main, but nei-
ther modifies, interprets, nor distributes them:
{
/* declare variables */
MPI_Init_thread(&argc, &argv, req, &prov);
/* parse arguments */
/* main program */
MPI_Finalize();
}
NOTES
The Fortran version does not have provisions for argc and argv and takes only IERROR.
It is the caller's responsibility to check the value of provided, as it may be less than what was requested in required.
The MPI Standard does not say what a program can do before an MPI_Init_thread or after an MPI_Finalize. In the Open MPI implementation, it
should do as little as possible. In particular, avoid anything that changes the external state of the program, such as opening files, read-
ing standard input, or writing to standard output.
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.
