<P><FONT SIZE=2> Hi,<BR>
<BR>
# Have you registered your username/password correctly (mpiexec -remove; mpiexec -register; mpiexec -validate)?<BR>
<BR>
# Can you run simple non-MPI programs like hostname (mpiexec -n 2 hostname)?<BR>
<BR>
# Are you using a shared drive for your executable (Use the "-map" option to map shared drives for your MPI job)?<BR>
<BR>
Make sure that you copy-paste the command and the output of the command in your email (Don't re-type).<BR>
On a side note, MPICH2 currently does not support heterogeneous systems. So you cannot run jobs spanning 32-bit and 64-bit systems.<BR>
<BR>

Subject: [mpich-discuss] MPICH2 and Windows Vista<BR>
<BR>
I'm having problems running mpich2 under windows vista.<BR>
<BR>
The systems are running<BR>
<BR>
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<BR>
System C: vista home basic sp2 32 bit - mpich2-1.1.1p1win-ia32<BR>
<BR>
earlier this year I had system A working. B and C were installed this week.<BR>
<BR>
On system A all I remember having to do was switch the Windows firewall off.<BR>
<BR>
with A, B and C I have now tried switching off<BR>
<BR>
Windows firewall<BR>
User Account Control<BR>
<BR>
On system A i can do<BR>
<BR>
smpd -install<BR>
<BR>
and from another dos box I can run<BR>
<BR>
smpd -status<BR>
<BR>
and this reports that smpd is running.<BR>
<BR>
However when trying<BR>
<BR>
mpiexec -n 4 mpi_example01.exe<BR>
<BR>
i get<BR>
<BR>
launch failed: CreateProcess(mpi_example01.exe) on 'hornbeam' failed, error 5 - Access is denied.<BR>
<BR>
launch failed: CreateProcess(mpi_example01.exe) on 'hornbeam' failed, error 5 - Access is denied.<BR>
<BR>
launch failed: CreateProcess(mpi_example01.exe) on 'hornbeam' failed, error 5 - Access is denied.<BR>
<BR>
launch failed: CreateProcess(mpi_example01.exe) on 'hornbeam' failed, error 5 - Access is denied.<BR>
<BR>
I get similar problems on B and C.<BR>
<BR>
Is this problem resolvable with Vista?<BR>
<BR>
If not what versions of the Windows operating system do people recommend with MPICH2?<BR>
<BR>
It is quite frustrating because I was getting quite good program speed up on the quad core system earlier this year.<BR>
<BR>
thanks in advance<BR>
