-The OpenAirInterface (OAI) software is composed of six different parts: 
-
-openair1: 3GPP LTE Rel-8 PHY layer + PHY RF simulation
-
-openair2: 3GPP LTE Rel-9 RLC/MAC/PDCP/RRC implementations, eNB application, X2AP. Note that for RLC, the following versions are userL UM_v9.3.0, TM_v9.3.0, and AM_v9.3.0. For PDCP, PDCP_v10.1.0 is used. For RRC, only LITE is used.
-
-openair3: 3GPP LTE Rel9 and 10 MME/NAS, S+P-GW, HSS, S1AP (ENB and MME).
-
-common: some common OAI utilities, other tools can be found at openair2/UTILS
-
-targets: scripts to compile and lauch different system targets (simulation, emulation and real-time platforms, user-space tools for these platforms (tbd))

+   Enable deadline scheduler of Linux kernel (>=3.14.x). 
 --disable-cpu-affinity
    Disables CPU Affinity between UHD/TX/RX Threads (Valid only when deadline scheduler is disabled). By defaulT, CPU Affinity is enabled when not using deadline scheduler. It is enabled only with >2 CPUs. For eNB, CPU_0-> Device library (UHD), CPU_1->TX Threads, CPU_2...CPU_MAX->Rx Threads. For UE, CPU_0->Device Library(UHD), CPU_1..CPU_MAX -> All the UE threads
