Thanks. The working recipe actually was

ÂÂÂÂÂÂÂ copy_requirements = "original_requirements";
ÂÂÂÂÂÂÂ set_requirements = original_requirements;

Using eval_set_requirements i get:

[root@ce02-htc ~]# condor_q -limit 1 -l 2927.0 -af RoutedFromJobId 
requirements
ClusterId = 2927
ProcId = 0
requirements = false
RoutedFromJobId = "3296.0"


Using set_requirements:

[root@ce02-htc ~]# condor_history -l -limit 1 2924.0 -af Owner 
LastRemoteHost ExitStatus requirements
Requirements = original_requirements
Owner = "dteam039"
ExitStatus = 0
LastRemoteHost = "slot1_1@wn-01-02-03********"Â <-- the only one with gpu

I expected to see Requirements = <what was specified in the original 
submit file>, however adding
-af original_requirements returns the expanded content of the original 
requirements:

[root@ce02-htc ~]# condor_history -l -limit 1 2924.0 -af Owner 
LastRemoteHost ExitStatus requirements original_requirements
original_requirements = ((TARGET.CUDACapability >= 1.2) && 
(TARGET.CUDADeviceName =?= "Tesla K40m") && true) && (TARGET.Arch == 
"X86_64") && (TARGET.OpSys == "LINUX") && (TARGET.Disk >= RequestDisk) 
&& (TARGET.Memory >= RequestMemory) && (TARGET.GPUs >= RequestGPUs) && 
(TARGET.HasFileTransfer)
Requirements = original_requirements
Owner = "dteam039"
ExitStatus = 0
LastRemoteHost = "slot1_1@wn-01-02-03********"
