JMeter_Synchronization Timer

I have to run 200 concurrent users from two JMeter Slaves (100 threads from each) such that 200 users first do login simultaneously, after completing login, all 200 users should do next printing operation simultaneously.
To achieve this, I am using synchronization timer at my JMeter Master:
1.If I set synchronization timer for 100, it send 100-100 simultaneous users in two bunches. It is not sending 200 simultaneous users in a single bunch.

2. If I set synchronization timer for 200, JMeter Master hangs.

Is there any way to run 200 simultaneous users from two or more JMeter slaves?

If I try to run 200 users from single Jmeter with synchronization timer set at 200, it gives following error in response to some login requests:

    I guess the problem may be in the RAM,

    Please check the RAM.
