While the presence of AC power ﬂow at the DSO level can be handled by using the exact second-order cone (SOC) relaxation method [24], [25], the method is valid only for radial topologies and cannot be used to handle the AC power ﬂow at the TSO level with the meshed ...

WebAbstract. We consider simple compiler optimisations for removing redundant memory fences in programs running on top of the x86-TSO relaxed memory model. While the optimisations are performed using standard thread-local control flow analyses, their correctness is subtle and relies on a non-standard global simulation argument.

Webper processor are also needed to implement TSO r The advantage of TSO is some of the write latency can be hidden r Other relaxed models (see Figures 8.39) relax other orderings but are also more complicated to implement or impose more restrictions on program implementation r Read latency can be hidden by relaxing R->R and/or R->W, but WebRelaxed ordering is a PCIe feature which allows flexibility in the transaction order over the PCIe. This reduces the number of retransmissions on the lane, and increases performance up to 4 times.

WebJul 4, 2011 · We address the problem of deciding robustness of a program against the total store ordering (TSO) relaxed memory model, i.e., of checking whether the behaviour under TSO coincides with the expected sequential consistency (SC) semantics. We prove that this problem is PSPACE-complete.

The basis for our technique is a novel representation of executions under TSO and PSO, called chronological traces. Chronological traces induce a partial order relation on relaxed … Webwhat's TSO's excuse? But if TSO relaxed the restriction, would ISPF be likely to follow?

Webrelaxed memory models, such as Total Store Order (TSO) and Partial Store Order (PSO) [5, 33]. For TSO and PSO, the veriﬁcation problem is more challenging because operations by the same thread may no longer follow the program order.
