I would like to run several cases in CFX one by one using a specific parallel method. How can I define this in Perl?

To run a case, say using the definition file case1.def, one can type the following command into the command line (a command window can be obtaining from the CFX Launcher by: CFX Launcher ->Tool->Command Line): cfx5solve -batch -def case1.def To do the same thing in Perl, one needs to quote the command and put system before it, i.e.: system (`cfx5solve -batch -def case1.def`); where system is a Perl function to execute a system command. To run case1.def in parallel, say MPICH Local Parallel for Windows, one can type the following in command line: cfx5solve -batch -def case1.def -start-method "MPICH Local Parallel for Windows" -part 2 where the part switch defines the number of partitions. To do the same thing in Perl, one need to use escape `` in Perl, i.e.: system ("cfx5solve -batch -def case1.def -start-method "MPICH Local Parallel for Windows" -part 2"); Basically, in a situation where we have double quotes within double quotes, one needs to use in Perl. This usually happens when user wants to specify parallel method and/or a host list. Now, if one wants to run several cases batch using a specific parallel method, one can put the following lines in the Perl script: system ("cfx5solve -batch -def case1.def -start-method "MPICH Local Parallel for Windows" -part 2"); sleep 5; system ("cfx5solve -batch -def case2.def -start-method "MPICH Local Parallel for Windows" -part 2"); sleep 5; system ("cfx5solve -batch -def case3.def -start-method "MPICH Local Parallel for Windows" -part 2"); The `sleep` command asks the script to wait for 5 seconds before initiating the next command. |
