We want to pass some options (a file path and a tree topology string) via MPISend() to a batch file, which will insert these into two different option arrays for two different method batch files that it will invoke.  We see how to create an options associative array in our top-level batch wrapper and pass it to MPISend().  What we do not understand is how to retrieve those two option values in our mid-level wrapper that calls the method batch files.  Help!!

Hi Ted,

If I understand your situation correctly, you have a high level wrapper which does something like


Code (]

for (i = 0; i < Abs(fileList); i+=1)
{
          filePath = fileList[i):

;           treeString = myTrees[i];          MPISend (nodeID, "mid_wrapper.bf", {"0":filePath, "1": treeString}); }

and you then mid_wrapper.bf makes other lists and passes them to other analyses.

Whatever you pass to MPISend as the third argument list is handled the same way as the call to


Code (]
ExecuteAFile ("mid_wrapper.bf", argument)
[/code):

would be in a non-MPI setting -- namely the values from 'argument' will be passed on to the standard input for "mid_wrapper.bf". Consequently, if you open "mid_wrapper.bf" with [code] fscanf (stdin, "String", filePath); fscanf (stdin, "String", treeString);

you should then be able to use filePath and treeString to pass them to 3-rd level files.

HTH,
