Run Multiple Inputs

[Arielle Miller]

I have several hundred runs i need to do.  I know it is possible to write scripts to get SCALE to run all of these either in parallel or in series without me having to manually do this.  I just don't know the syntax to write the script and I don't know how to get SCALE to start the run (i assume it has to be via the c:\ prompt) the script.  I'm running SCALE 6.2.1.

Can anyone help me with this?

Hi Arielle,

You could run jobs serially via a simply Windows Batch script file. A warning is that the script will not stop until the jobs are done or the script has been terminated. So attempting to terminate the SCALE jobs will not stop the next SCALE job from starting. You will need to find the Batch file in you task manager and terminate it.

Copy the contents of the script below into a file locally on your machine and update the paths to SCALE and your inputs.

SerialRunAll.bat:

for %%F in (C:\SCALE-6.2.1\playground\inputs\*.inp) do C:\SCALE-6.2.1\bin\scalerte.exe %%F

You will need to update C:\SCALE-6.2.1\playground\inputs\*.inp to be the location of your input files and C:\SCALE-6.2.1\bin\scalerte.exe to be the path to your SCALE installation. 

A simple way to increase throughput is to copy the SerialRunAll.bat to the number of cores on your machine and update the inputs to be different, e.g., C:\SCALE-6.2.1\playground\inputs\coreN\*.inp  

When N is 1 through 4 or 8, etc.. 

Hope this helps.

Best regards,

I tried.  It didn't work.  I attached the file (as a .txt not a .bat).  I'm not sure what i'm doing wrong.

Hi Arielle,

When you state it didn't work, what occurred?

Looking at your script the only issue appears to potentially be the whitespace in your directory path. These can confuse batch scripts as the script sees two arguments, whitespace separated.

I suggest renaming the directory and replacing the whitespace with an underscore. Additionally, you should be able to wildcard your file names into a single for loop expression:

for %%F in (C:\Users\mille\Documents\Paper\Plutonium_Nitrate\punitrate*.inp) do C:\SCALE-6.2.1\bin\scalerte.exe %%F

Please note the Plutonium_Nitrate has been updated to include an underscore. Also the '*' wildcard character will match the same names you have listed.

I got a command prompt to run but it didn't result in the output file or other files that keno should produce.  I know the files themselves don't have any errors b/c i have run them individually.  I'll try getting rid of the white space.

I got it work.  Thanks!  I put the bat file in the c:\SCALE-6.2.1 folder and ran it from the \playground\input\core2 folder i setup.  Ran perfectly behind the scenes.  :-)
