Short answer:
You need to create the function on schema level, that is outside the module.
Then you can simply call it by either
1) Having both modules in the same schema
2) Specify a PATH in comp1 module esql file "importing" the schema used by comp2 module
3) Call the function with the full schema name used by comp2 included in the comp2 call (eg CALL com.ibm.common.myFunction('helloworld!'))
Long answer:
Find it in the ESQL programming guide.

Define FUNC2 outside the module of Compute1 and make a call of Func1 in both compute1 and compute2
You can even define it in a separate eSQL file and ensure that PATH and schema clauses are taken care of..

functions in a module is "private",only accessable for other functions in the same module
you can define your "global" function outside module (in schema 1), then other functions in other module of different schema (in schema 2) can use that "global" function by adding "path" in schema 2 |

| It is always good to have seperate esql file which contais the common functions and then utilize them as beans. |
