Can we distribute the TestNG tests in Selenium Grid when running the tests in parallel but in the same browser

Question

Problem Statement: i have 100 test cases which i am willing to run using Selenium Grid 2 but only in Chrome using two Nodes. Is it possible to divide the test cases 50 per system in Grid. Because when i run the 100 Test Cases in parallel selenium runs all the test cases in both the systems and the tests fail(at times). Though i am using ThreadLocal to create the WebDriver Instance.Like you can see below the same test runs on both the nodes, but what i want the tests to not repeat itself and run parallely on the same browser.

Answer 1

was able to do it with parallel="classes" and adding the classes to the testNG.xml file.
