Setting of trialGpuNumber and maxTrialNumberPerGpu

[Simba98]

There are 4 remote ssh machines and each one has one GPU.
I try to set
trialGpuNumber: 1
trialConcurrency: 16

And then for each machine in machineList:
I have:
maxTrialNumberPerGpu:4
useActiveGpu: true

I expected there would be 16 trails running parallel, 4 on each.
But actually, 4 are running and 12 are waiting.

Actually, I found a trick. By duplicating the remote multiple time in the machinelist and set maxTrialNumberPerGpu:1 for each one.
