star cd 4.06 parallel problem
 
the problem is as follows,

C:\Program Files\CD-adapco\STAR-CD\4.06\bin\star.exe -decompmeth=x -mpi=mpich2 2 PNP: Initialized [2008-10-19-10:46:58] Automatic Sequential Automatic Parallel analyzer. PNP: Allocated "xy,2" resource (2 processes). PNP: Assigned "xy,2" resource to STAR solver (2 processes). PNP: Loading STAR solver dynamic shared object plug-ins. PNP: Loading MPICH2 1.0.6 dynamic shared object plug-ins. PNP: Spawning STAR processes on single node. Credentials for xy rejected connecting to xy Aborting: Unable to connect to xy PNP: Shutdown [2008-10-19-10:47:00] Execution aborted by request (SIGABRT) after 2 seconds (OVERALL ELAPSED TIME).

I have no idea to deal with this problem, who could you give me some advices, thanks.

try to run via the star-shell (help-> star-shell). The starlaunch never works very well. The problem could be differentiated from starlaunch using star-shell.

cheers,

it also doesn't work well when use the star shell ,the problem is, Administrator@xy ~ $ star -mpi=mpich2 xy,2 PNP: Initialized [2008-10-20-19:52:49] Automatic Sequential Automatic Parallel analyzer. PNP: Allocated "xy,2" resource (2 processes). PNP: Assigned "xy,2" resource to STAR solver (2 processes). PNP: Loading STAR solver dynamic shared object plug-ins. PNP: Loading MPICH2 1.0.6 dynamic shared object plug-ins. PNP: Spawning STAR processes on single node. Credentials for xy rejected connecting to xy Aborting: Unable to connect to xy PNP: Shutdown [2008-10-20-19:52:50] Execution aborted by request (SIGABRT) after 1 seconds (OVERALL ELAPSED TIME).

Please can you tell me what is the name of your uname -n? Did you give the right name? Did you try to run it in xy,1 and it worked? Do you have license for 2 processes? Check starhpdomains and starpar in your license file. xy is one processor with 2 cores?
