Maximum concurrency of ComputeTask

[y]

Hi Everyone：

  When multiple users were calling the same computeTask through the thin 
client, I noticed that there is a limit to the maximum number of computing 
tasks running simultaneously on the server.  In my server, 30 or 31 
ComputeTasks can be run simultaneously at most. No matter how increasing the 
number of users, it still can only run 30 computeTask on Server.  How can i 
improve the maximum number of running task？

Thanks,
