Hi,
  Open a command prompt with administrator privileges (Right-click on
command prompt icon and select "Run as administrator") and use the windows
installer from command line to install MPICH2.
  To uninstall MPICH2 (It is recommended that you uninstall MPICH2 before
installing a new version) run the following at the command prompt (with
admin privileges),

   msiexec /x mpich2-1.2.1-win-ia32.msi

  To install MPICH2 run the following at the command prompt (with admin
privileges),

   msiexec /i mpich2-1.2.1-win-ia32.msi

  Let us know if you still have problems.

(PS: Running msiexec at the command prompt should bring up the GUI for
installing MPICH2.)

Regards,
Jayesh

Subject: [mpich-discuss] smpd on windows 7

I have been using MPICH2 on Windows XP (as well as under linux) for
over 2 years.

I am now moving to Windows 7 on a new PC.  I have downloaded and
installed the most recent MPICH2 for Windows and the install appears
to have been OK.  However, the smpd refuses to install as a
service.  smpd never shows up in the Task Manager's list of
services.  I have run 'sc //hostname query smpd', and it says the
'specified service does not exist as an installed service'.

I have redone the full install several times, under 2 different admin
accounts (one of them named 'administator').  I have tried the
explicit smpd -install as well (varying accounts, directory
locations. etc.), and routinely receive the message:

OpenSCManager Failed:
Access is denied. (error 5)
Unable to remove  the previous installation, install failed.

If I try smpd -uninstall, I get the same OpenSCManager Failed... message.

Any advice would be greatly appreciated

Hi,
  There is a bug in your code which results in accessing invalid indices of
the status array.
  Please modify the for loop in your code as below and let us know if it
works for you.

Sorry for the late reply but I was out of the country for a week. I am
using MPICH2 1.2.1 on a WinXP SP3 machine running an Intel Core i5

Hi,
  Let me take a look at this and get back to you.
  Meanwhile, if you are planning to work with C/C++ MPI programs (not
fortran MPI programs) you can install MPICH2 on windows and use the gcc libs
(you can even compile/link directly with the windows mpi libraries with gcc)
provided with the installation.

(PS: To install MPICH2 on Vista/windows_7 type "msiexec /i mpich2-1.2
1-win-ia32.msi" from an administrator command prompt. Right-click on the
command prompt icon and select "Run as administrator" to run a command
prompt with admin privileges. Similarly to uninstall MPICH2 type "msiexec /x
mpich2-1.2.1-win-ia32.msi".)
Regards,
Jayesh

Well, it works. Finally. But with one little snag--see below.

    System: Windows Longhorn/Vista (not yet supported!) Ver 6.0 Build 6002
Service Pack 2
    uname:  CYGWIN_NT-6.0-WOW64 Crawley 1.5.25(0.156/4/2) 2008-06-12 19:34
i686 Cygwin
    CPU:    AMD Phenom X4 9550
    gcc:    gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
    MPI:    mpich2-1.2.1
    config: ./configure --prefix=/home/gustav/mpich2-1.2.1
--disable-sharedlibs --enable-timer-type=gettimeofday --with-device=ch3:ssm
--with-thread-package=pthreads

An important step that must be emphasized for Cygwin users is that to
enable XSI IPCs (this activates shared memory too) Cygserver must be
run on the machine. See /usr/share/doc/Cygwin/cygserver.README for
more info. Also, the CYGWIN environmental variable must be set to
"server". This is described in the doc, as well.

With all this done and MPI compiled and installed, it works for a user
with admin privileges. Here's a brief demo:

    root at Crawley 515 # echo $CYGWIN
    server
    root at Crawley 516 # which mpdboot
    /home/gustav/mpich2-1.2.1/bin/mpdboot
    root at Crawley 517 # mpdboot --ncpus=4 --verbose
    running mpdallexit on Crawley
    LAUNCHED mpd on Crawley  via
    RUNNING: mpd on Crawley
    root at Crawley 518 # mpirun -np 4 hostname
    Crawley
    Crawley
    Crawley
    Crawley
    root at Crawley 519 # mpirun -np 4 /home/gustav/src/MPI-tests/hellow2.exe
    Crawley: hello world from process 0 of 4
    Crawley: hello world from process 1 of 4
    Crawley: hello world from process 2 of 4
    Crawley: hello world from process 3 of 4
    root at Crawley 520 # mpdallexit
    root at Crawley 521 #

Alas, there is a little snag. User "root" has admin privileges. User
"gustav" does not. And here is what happens when this hapless
individual attempts the same:

    gustav at Crawley 556 $ echo $CYGWIN
    server
    gustav at Crawley 557 $ mpdboot --ncpus=4 --verbose
    running mpdallexit on Crawley
    LAUNCHED mpd on Crawley  via
    RUNNING: mpd on Crawley
    gustav at Crawley 558 $ mpirun -np 4 hostname
    Crawley
    Crawley
    Crawley
    Crawley
    gustav at Crawley 559 $ mpirun -np 4 /home/gustav/src/MPI-tests/hellow2.exe
    Assertion failed in file mpidi_pg.c at line 277: ((pg)->ref_count) == 0

      exit status of rank 0: killed by signal 9
    gustav at Crawley 560 $ mpdallexit
    gustav at Crawley 561 $

On the other hand, this little non-MPI program that tests shared memory
stuff still works for the non-admin user:

    gustav at Crawley 563 $ cat shm.c
    #include <stdio.h>
    #include <sys/types.h>
    #include <sys/ipc.h>
    #include <sys/shm.h>

    int main(int argc, char *argv[])
    {
  int shmid;

  if((shmid = shmget(IPC_PRIVATE, 1, IPC_CREAT)) == -1){
      perror("shmget");
  }
  shmctl(shmid, IPC_RMID, NULL);
    }

    gustav at Crawley 564 $ cc -o shm shm.c
    gustav at Crawley 565 $ ./shm
    gustav at Crawley 566 $ echo $?
    0
    gustav at Crawley 567 $

Question: Why can't the non-admin user execute the MPI program?

Jayesh,

Thanks for the response, but it still does not work.

Previously I had just been executing the .msi file from my admin
account.  This time I uninstalled (which said it was successful) and
then installed the MPICH2, using msiexec from the command line as you
suggested.  The GUI came up,  and all seemed fine (I kept the default
smpd password and installed for all users).  And indeed, as before I
have all  the MPICH2 directories and files in my Program File (x86)
directory.  However the smpd service is not being installed.

I've checked on the Task manager - it's not there.
I tried    sc \\hostname query smpd      and it  now says

[SC] EnumQueryServicesStatus: OpenService FAILED  1060:
The specified service does not exist as an installed service.

My parallel executable is called m2.  When I try

   mpiexec  -n 1 -localonly  m2

I get a request for the smpd passphrase , which I supply.

mpiexec (I assume) then comes back with

Unknown option : -d
missing numproc flag: -n , -np, -hosts,  or -localonly
Unable to parse mipexec command arguments
ReadFile() Failed, error 109
unable to start the local smpd manager

I get the same response if I try    mpiexec  -n 2
-localonly  m2    or     mpiexec  -localonly 1 m2 .

I'm pretty sure that the problem is that the smpd service is not
being installed.

One additional  piece of info.  This is a 64 bit machine, and the m2
I am running is a 32 bit version.  But it runs fine in serial on this
machine.

Thanks for you  help,
Sherry

Thanks,

Unfortunately my applications are  both C and Fortran.  But so far
I've been able to compile and link (using the MPICH2 libraries)
on  my windows 7 machine.  I just can't run under mpiexec. (I've
tried executables built on  the windows 7 machine  & older
executables built under XP with the same results).

I'll wait to hear from you.

Hi,
  Can you see MPICH2 process manager in the list of services (Look at
Control Panel\System and Security\Administrative Tools\Services)? Also check
the status of the service (Is it started ?)?
  You don't have to supply the "-localonly" flag to run MPI processes on the
local machine. MPICH2 by default launches the processes on the local machine
("mpiexec -n 1 m2" should launch m2 on the local machine).
  Can you run a simple non-MPI program (mpiexec -n 2 hostname)?

Regards,
Jayesh
