Parallel Solver
 
Hi,

I would like to know, how can I run the Phoenics with all core in the same processor?

Any advice would be greatly appreciated.

It denpends on your license type. You can contact your vendor.

You need to be sure that you have parallel licence. If you can run parallel PHOENICS then you should install MPICH2 and use following line, for example for 2 processes:

%MPICH2%\bin\mpiexec.exe -np 2 -localroot -channel auto %phoenics%\d_earth\d_windf\earexe.exe -par

%MPICH2% and %phoenics% should be correct paths to MPICH2 and PHOENICS on your PC.

hi,

I tried to start phoenics in parallel using a batch file. I want to use 4 processors but I'm alway getting an error telling me:
'c:\program' is not recognized as an internal or external command

this is how my batch file looks like:

cd c:\project\case1
C:\Program Files\MPICH2\bin\mpiexec.exe -np 4 -localroot -channel auto
C:\phoenics\D_SATELL\d_windf\satexe.exe f
C:\phoenics\D_EARTH\d_windf\earexe.exe -par

Does anybody knows how to fix this problem?
MPICH2 is installed proper and my license file is for 4 processors.

cheers

Hi Wikie,

It could be due to the blank in C:\Program Files. Try using quotation marks:
"C:\Program Files\MPICH2\bin\mpiexec.exe -np 4 -localroot -channel auto"

Hi Wikie,

Change your batch file as
cd c:\project\case1
C:\phoenics\D_SATELL\d_windf\satexe.exe f
"C:\Program Files\MPICH2\bin\mpiexec.exe" -np 4 -localroot -channel auto C:\phoenics\D_EARTH\d_windf\earexe.exe -par
