Running batch of test scripts in different test

Hi,

We have around 400 test scripts stored in ALM 11.00. What is the best way to schedule the test runs in different PCs where QTP is available?

Let's say there are 5 PCs where QTP is installed and are available to run the test scripts. How can we invoke QTP in these 5 PCs and run the tests like 80 scripts in each PC?

There is a RUN Test set option but here we have to configure the Hosts manually each time. Is there a better and easy way to do this? Like a script that can read the host names from a text file or something?

How is this scenario handled generally where huge set of test scripts are available like 5000, 10000 test scripts etc. ? Is the Run Test Set option the only way followed?

Any other alternate method is also welcome.

Thanks.
