So, the total number of Logical CPUS should be 226 (2 quadcore CPUS per WN) * 4 (4 cores per quadcore CPU) = 904. On top of that, I should apply the overbooking factor. >> >> 3./ I've set up "GlueHostProcessorOtherDescription: >> Cores=8,Benchmark=54.90-HEP-SPEC06".

Is my assumption right? > actually you should publish "Cores=4,Benchmark=54.90-HEP-SPEC06", > because 4 is the number of cores per cpu on the typical WN After Gonzalo comment, I realized that the Benchmark value should be per core. Thanks in Advance Cheers Goncalo
