Executing a BAT sript with white space in its path + passing arguments with white spaces

Diego_R_ — Thu, 27 Apr 2017 15:28:04 GMT

Dear All,

We recently switched from mpich2 to intel mpi. I have problems starting a bat script when the path to the script and the argument passed to the script both contain whitespaces:

"path-To-MPI\mpiexec" -delegate -n 1 "path with spaces"\test.bat "argument with space"

Is there a solution to this problem ?

Thanks

Diego

Example 1) :

J:\Users\diego>"C:\Users\diego\AppData\Local\XXX Software\MPI\impi5\mpiexec.exe" -delegate -n 1 "J:\Users\diego\abc DRuiz\test2.bat" "tu tu"

'J:\Users\diego\abc' is not recognized as an internal or external command, operable program or batch file.

2) If my argument does not contain white spaces, then it works

J:\Users\diego>"C:\Users\diego\AppData\Local\XXX Software\MPI\impi5\mpiexec.exe" -delegate -n 1 "J:\Users\diego\abc DRuiz\test2.bat" "tu-tu"

J:\Users\diego>echo LOCAL "test2.BAT" STARTED
LOCAL "test2.BAT" STARTED

3) If I use an executable instead of a BAT script, it also works:

J:\Users\diego>"abc DRuiz\qt2.bat

J:\Users\diego>"C:\Users\diego\AppData\Local\XXX Software\MPI\impi5\mpiexec.exe" -delegate -n 1 "J:\Users\diego\abc DRuiz\bin\abcd.exe" "tu tu"

Hi Diego,

You have also submitted the issue via Intel Online Service Center, I have reproduced the issue and escalated it to the developers. Thanks.

Best regards,

It does not seem to work with

Diego_R_ — Tue, 13 Jun 2017 07:24:01 GMT

It does not seem to work with mpiexec; Could you provide a sintax working with mpiexec ?

Edit, added:

C:\>mpiexec -n 1 "C:\test\diego\abc DRuiz\test2.bat" "X Y" "a b"
'C:\test\diego\abc' is not recognized as an internal or external command,
operable program or batch file.

So the problem is not on the program, but rather on the arguments. Let me experiment more...

Awful hack:

Awful hack:

C:\>type "test\diego\abc DRuiz\test2.bat"
echo arg1=%arg1%, arg2=%arg2%

C:\>set arg1=X Y

C:\>set arg2=a b

C:\>mpiexec -n 1 "C:\test\diego\abc DRuiz\test2.bat"

C:\>echo arg1=X Y, arg2=a b
arg1=X Y, arg2=a b

Using environment variables to pass args, ugly as it is, may get you by for now.

I do not like the solution

Diego_R_ — Fri, 16 Jun 2017 15:27:31 GMT

I do not like the solution with environment variables for two reasons:

1) I will need to pass the environment variable to remote processes (kind of ok with -genvall or similar)

2) Each call to mpiexec made by my application needs to set a different value to the environment variable. Therefore I can not make concurrent calls anymore* !! (For example, we start 10 different mesh generations simultanesouly, each one relying on a mpi session ).

* Using different environment variable names is not a solution: If I have to write the script to change the variable name each time, then I also need to transmit the script to remote computers ... Furthermore, if the script needs to be slightly different on each machine, then I have to prefetch it ... and I need to clean used environment variable names ... plus risk of environment variable name collision.
