[mpich-discuss] MPICH2 and Windows Vista

[Jayesh Krishna]

 Hi,

#  Have you registered your username/password correctly (mpiexec -remove;
mpiexec -register; mpiexec -validate)? 

# Can you run simple non-MPI programs like hostname (mpiexec -n 2
hostname)?

# Are you using a shared drive for your executable (Use the "-map" option
to map shared drives for your MPI job)?

  Make sure that you copy-paste the command and the output of the command
in your email (Don't re-type).
  On a side note, MPICH2 currently does not support heterogeneous systems.
So you cannot run jobs spanning 32-bit and 64-bit systems.

Regards,
Jaeysh

I'm having problems running mpich2 under windows vista.

The systems are running

System A:  vista home premium sp2 64 bit - mpich2-1.0.8-win-x86-640 System
B:  vista home premium sp2 64 bit - mpich2-1.1.1p1-win-x86-64
System C:  vista home basic   sp2 32 bit - mpich2-1.1.1p1win-ia32

earlier this year I had system A working. B and C were installed this
week.

On system A all I remember having to do was switch the Windows firewall
off.

with A, B and C I have now tried switching off

   Windows firewall
   User Account Control

On system A i can do

   smpd -install

and from another dos box I can run

   smpd -status

and this reports that smpd is running.

However when trying

mpiexec -n 4 mpi_example01.exe

i get

launch failed: CreateProcess(mpi_example01.exe) on 'hornbeam' failed,
error 5 - Access is denied.

launch failed: CreateProcess(mpi_example01.exe) on 'hornbeam' failed,
error 5 - Access is denied.

launch failed: CreateProcess(mpi_example01.exe) on 'hornbeam' failed,
error 5 - Access is denied.

launch failed: CreateProcess(mpi_example01.exe) on 'hornbeam' failed,
error 5 - Access is denied.

I get similar problems on B and C.

Is this problem resolvable with Vista?

If not what versions of the Windows operating system do people recommend
with MPICH2?

It is quite frustrating because I was getting quite good program speed up
on the quad core system earlier this year.

thanks in advance
