[Condor-users] Matchmaker algorithm

[Gabriel Mateescu <gabriel.mateescu@xxxxxx>]

Hi,

What effect does the ranking that 
the resources specify for the jobs 
have on the matchmaker?

For example, these classads:

job1
Rank = TARGET.Memory
Memory = 1024
Requirements = Memory >= 1024 

job2
Rank = TARGET.Memory 
Memory = 512
Requirements = Memory >= 512 

resource1
Rank = 8096 - TARGET.Memory 
Memory = 2048

resource2
Rank = 8096 - TARGET.Memory 
Memory = 1024

Both jobs match both resources and both 
prefer resource1, but both resources 
prefer job2. 

What role does the resource preference play 
in making resource allocation decision?


Thank you.

Gabriel
