Incorrect interpolation and misrepresenting image positions could result in inaccurate measurements measurements, causing patient harm. Courtesy of Canon Medical Group13 Aurora Innovation Everything could go wrong “The inherent complexity of the real world and the continuous change of requirements result quality is a collective effort. Shift-left testing reduces development cost and improves ef�ciency. Effective communication about software quality helps improve it. Reward and promote continuous improvements

itr = std::find(vec.begin(), vec.end(), 3); itr != vec.end()) { *itr = 4; } Is it similar to the Go? Initializer list Initialization is a very important language feature, the most common one is when need to use according to the actual scene, to get better performance. Although std::tuple is effective, the standard library provides limited functionality and there is no way to meet the requirements intermediate state). The research on synchronization conditions has a very long history, and we will not go into details here. Readers should understand that under the modern CPU architecture, atomic operations

pipelined code: a += (v3[i]) ? (v1[i]+v2[i]) : (v1[i]*v2[i]) ● Performance critically depends on how effective the predictor is load:v1[i]...v3[i] cmp[i]:v3[i]==0 jump if true a[i]:a+=v1[i]+v2[i] jump a[i]:a+=v1[i]*v2[i] v2[i] ● Branch misprediction and pipeline flush at the end of the loop ● Branch predictor is effective – pipelining works – CPU utilization is good load:v1[i] load:v2[i] s[i]:v1[i]+v2[i] a[i]:a+=s[i] next instruction is data-dependent ● Workaround is branch prediction – guess the next instruction and go on ● Limiting factor is the ability to guess the future ● Workaround is writing unconditional code
