we show how to avoid explicit loop unrolling by using the SMT Theory of Lists to model feasible, potentially unbounded program traces. We argue that this approach is easier to use, and, more importantly, increases the confidence in verification results over the typical bounded approach. To...
For example, a recent model-based theory combination approach =-=[7]-=-, in which the solver keeps a model for each theory, takes the optimistic stance of eagerly propagating all equalities that hold in the model (whether or not they are truly implied), obtaining impress......

We asked a range of questions and asked our customers to score them out of 5 – for example, “In general, how satisfied are you with the clarity of the explanation of advice offered?”– with ‘1’ being ‘Very Dissatisfied’ and ‘5’ being ‘Very Satisfied’. We then get an averag...

As previously mentioned, in theory this feature can be bolted on the SIMD model: just compute your addresses (say, lut+b[i]) in vector registers, and add a rand_vec_load instruction. However, such an instruction would have a fairly high latency. As we'll see, the SIMT model naturally...

The performance of the new Ryzen 7 CPU from AMD has beed causing a lot of controversy: it is faster than its competitor in some tests, but it is slower in other ones, and several theories have been raised about the reason why. A popular theory says that disabling the SMT feature, the...
