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

Wed Sep 14 10:15:33 CDT 2011

Hi,
 To create an administrator command prompt Right-click on the command prompt icon and select "Run as administrator" (It is NOT enough to open a command prompt as an administrator to get an administrator command prompt).
 Try running your job from the administrator command prompt and let us know if it works.

Regards,
Jayesh

Nice! No access issues!!! 

I get the following from running LAMMPS: 

The application is unable to start correctly (0xc000007b). Click OK to close the application. I'm guessing this error is coming from LAMMPS and is related to how it's calling MPICH? 

Thanks for the help on the access issue.

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.

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!
