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...

Hi,
I am triying to run this script in order to find the pid for each open port and when I run it in one server it give me an error and for another server is not showing the same error. Below I pasted the script and the result.

fftw-wisdom-to-conf
FFTW-WISDOM-TO-CONF(1) fftw FFTW-WISDOM-TO-CONF(1)NAME
fftw-wisdom-to-conf - generate FFTW wisdom (pre-planned transforms)
SYNOPSIS
fftw-wisdom-to-conf [< INPUT] [> OUTPUT]
DESCRIPTION
fftw-wisdom-to-conf is a utility to generate C configuration routines from FFTW wisdom files, where the latter contain saved information
about how to optimally compute (Fourier) transforms of various sizes. A configuration routine is a C subroutine that you link into your
program, replacing a routine of the same name in the FFTW library, that determines which parts of FFTW are callable by your program.
The reason to do this is that, if you only need transforms of a limited set of sizes and types, and if you are statically linking your pro-
gram, then using a configuration file generated from wisdom for those types can substantially reduce the size of your executable. (Other-
wise, because of FFTW's dynamic nature, all of FFTW's transform code must be linked into any program using FFTW.)
FFTW is a free library to compute discrete Fourier transforms in one or more dimensions, for arbitrary sizes, and of both real and complex
data, among other related operations. More information on FFTW can be found at the FFTW home page: http://www.fftw.org
fftw-wisdom-to-conf reads wisdom from standard input and writes the configuration to standard output. It can easily be combined with the
fftw-wisdom tool, for example:
fftw-wisdom -n cof1024 cob1024 -o wisdom
fftw-wisdom-to-conf < wisdom > conf.c
will create a configuration "conf.c" containing only those parts of FFTW needed for the optimized complex forwards and backwards out-of-
place transforms of size 1024 (also saving the wisdom itself in "wisdom").
Alternatively, you can run your actual program, export wisdom for all plans that were created (ideally in FFTW_PATIENT or FFTW_EXHAUSTIVE
mode), use this as input for fftw-wisdom-to-conf, and then re-link your program with the resulting configuration routine.
Note that the configuration routine does not contain the wisdom, only the routines necessary to implement the wisdom, so your program
should also import the wisdom in order to benefit from the pre-optimized plans.
