Minor Description
---------------------------------------------
STEPS FOR REPRODUCE
---------------------------------------------
1. Run ScalaPiCalculationExample
2. Remember the result
3. Run one Compute Node
4. Run ScalaPiCalculationExample
5. Remember the result
6. Stop node from step 3
7. Run 4 compute nodes (for example, 2 from command line, and 2 from Idea IDE)
8. Run ScalaPiCalculationExample
9. Compare results from 2, 5 & 9 steps
---------------------------------------------
ACTUAL RESULT
---------------------------------------------
The results are different beginning from the eleventh decimal place:
Pi estimate: 3.141592653590042 - no one Compute Node is started
Pi estimate: 3.141592653589823 - one Compute Node is started
Pi estimate: 3.141592653589794 - four Compute Node are started
Please, clarify is this bug or feature?
---------------------------------------------
EXPECTED RESULT
---------------------------------------------
The results aren't depended from number of started nodes

ADDITIONAL INFO
---------------------------------------------
Is also reproducible for GG 6.6.3-p1 (ver. 6.6.3-p1-ent#20150228-sha1:ece6cbbd) - with the same values of Pi
