[julia-users] Julia Install in Heterogenous Linux Environment: Target architecture mismatch

We have a Linux cluster that consists of different models of hardware. If I build Julia on one kind of hardware, say model name : Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz but then run that installation on another kind of hardware, say model name : Intel(R) Xeon(R) CPU E5-2670 0 @ 2.6

[julia-users] Performance and Size problem with JLD saving DecisionTree model
