Scripting parameter: for + conditional

[rgrima]

Hello

I am trying to define an experiment using JUBE, where I test a different amount of nodes:
<parameter name="nodes" type="int">1,2,4,8,16</parameter>

I would also like to test a different combination of processes and threads:
<parameter name="taskspernode" type="int">1,2,4,8,14,28,56,112</parameter>

This works properly. It also can be written as an scripting parameter:
<parameter name="taskspernode" mode="python">",".join([ str(i) for i in [1,2,4,8,14,28,56,112] ])</parameter>

But, I cannot use conditionals inside this loop. For instance, I would like to limit the total number of processes:
<parameter name="taskspernode" type="int" mode="python">",".join([ str(i) for i in [1,2,4,8,14,28,56,112] if $nodes*i<=768])</parameter>

I get an error message from jube:
not well-formed (invalid token): line 45, column 124

Some characters are not allowed inside an XML script or at least not inside a tag-option. Here are some of the typcial replacments:

• < : <
• > : >
• & : &
• " : "
• ' : '

see FAQ: https://apps.fz-juelich.de/jsc/jube/docu/faq.html#xml-character-handling

Please try the following:
<parameter name="taskspernode" type="int" mode="python">",".join([ str(i) for i in [1,2,4,8,14,28,56,112] if ${nodes}*i &lt;=768])</parameter>
