[mpich-discuss] LAMMPS execution on Windows 7 no SP1 using MPICH 2.0-1.4.1p1 for windows

[Jayesh Krishna]

Hi,

>> MPICH2 not installed or unable to query host ...
 This is due to a bug in wmpi* wrapper programs. This does not indicate a faulty installation. Try running "mpiexec -n 2 c:\Progra~1\MPICH2\examples\cpi.exe" and see if it works.

>> Unable to open the ...
 Try running the command from an administrator command prompt (Right-click on command prompt icon and select "Run as administrator".)

 Let us know if it works.

Regards,
Jayesh

I can see smpd running as a service. smpd responds to start and stop commands. 

MPICH2 Configurable Settings reports 

"spike: MPICH2 not installed or unable to query host" 

I used the wmpiregister.exe to associate "behappy" with my mike account. I copied the mpich2mpidll to the winlaamps directory along with the 
mpiexec.exe. 

I turned off the windows firewall and disabled it. I turned off the Norton firewall and it is disabled as well. 

The lmp6.exe is a LAMMPS EXE file copied directly from the LAMMPS site. 



C:\winlaamps>mpiexec -np 4 -localonly c:\winlaamps\lmp6 < in.water5 
Unable to open the HKEY_LOCAL_MACHINE\SOFTWARE\MPICH\SMPD\process\6240 registry key, error 5, Access is denied. 

Unable to open the HKEY_LOCAL_MACHINE\SOFTWARE\MPICH\SMPD\process\3572 registry key, error 5, Access is denied. 

Unable to open the HKEY_LOCAL_MACHINE\SOFTWARE\MPICH\SMPD\process\7056 registry key, error 5, Access is denied. 

Unable to open the HKEY_LOCAL_MACHINE\SOFTWARE\MPICH\SMPD\process\7060 registry key, error 5, Access is denied. 

I was hoping to get LAMMPS to run quicker (divide and conquer)in a multicore environment. 

Thanks in advance for any insight!
