EDZL (EDF / Zero Laxity first), right? AFAICR, there's quite a lot of analysis on EDZL for multi-cores... eg, Insik Shin et al.... http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=6374195 But, before going the EDZL way, isn't it worthwhile to consider just splitting tasks among 2 cpus https://people.mpi-sws.org/~bbb/papers/pdf/rtss16b.pdf ? ... we're working at RETIS on simpler ways to make the AC for these split tasks cases (cc-ing Alessandro) that doesn't need demand-bound complex analysis...
