and i did some test,the following is result, i also notice that the user
only use 11G memory,due to the resource-calculator is based on memory ,i
guess if i let allocate more
memory ,it can allow more job run parallel, the Total memory list in my
is 24G ,i wander why the user can not take all 24G memory for running it's
jobs? any options limit?
2 job running (small memory)
1 job running(small memory)
3 job running (small memory require job)
1 job running (large memory require job),3 job blocked
2 job runnning
