As per it is 24 process the query been split into 24 parallel threads.

Settings for Cost Threshold for Parallelism is 30 and Max Degree of Parallelism is 0 (default).

Cannot see anything going in Profiler and all the thread above are waiting for CPU Time.

How to find what is SQL Server doing and what is holding up the CPU?

    I would start with looking at the waiting tasks dmv to see the types of resources which the query is waiting. Also the query plan being used by the current executing statement.

    SELECT      *
FROM        sys.dm_os_waiting_tasks
WHERE       session_id = 141

SELECT      q.query_plan,
            r.*
FROM        sys.dm_exec_requests                    r
CROSS APPLY sys.dm_exec_query_plan(r.plan_handle)   q
WHERE       session_id = 141
