It is right there in the fifth field.
L1d level 1 data cache.
L1i level 1 instruction cache.
L2 level 2 cache.
L3 level 3 cache.
Looking at the table, the L1 and L2 are private, but all the processors in a same socket (there are two) share the same L3 cache.
The fact that the same information repeats twice indicates that you have a multithreading system.

No, see man 7 pid_namespaces:
The namespace init process
The first process created in a new namespace (i.e., the process created
using clone(2) with the CLONE_NEWPID flag, or the first child created

The .mo file contains the translation, and if it not found, messages are usually displayed in English. From the pathnames, your locale seems to be en_US, so you shouldn't need a translation.
A hint to the problem is here:
6260 write(2, &...

When you have this many arguments, you want to pass them to GNU Parallel via standard input (stdin) or via files.
I would do something like (untested):
$f = popen("parallel","w");
fwrite($f,$commands);
close ($f);
This way you may be able to avoid the temporary file.
