David A. Panek has 18 years of experience in cost engineering. He has expertise in tolerance analysis, Monte Carlo techniques, cost estimation, and neural costing. The document discusses different methods for tolerance analysis including worst case, statistical, and six sigma approaches. It also defines terms related to process variation and discusses measures of process capability like Cp and Cpk. Guidelines are provided for designing optimized tolerances through establishing process standard deviation and computing probabilities to achieve tight assembly gaps.

Optimize Single Particle Orbital (SPO) Evaluations Based on B-splinesIntel® Software
Orbital representations that are based on B-splines are widely used in quantum Monte Carlo (QMC) simulations of solids, which historically take as much as 50 percent of the total runtime. Random access to a large four-dimensional array make it challenging to efficiently use caches and wide vector units in modern CPUs. So, we present node-level optimizations of B-spline evaluations on multicore and manycore shared memory processors.
To increase single instruction multiple data (SIMD) efficiency and bandwidth utilization, we first apply data layout transformation from an array of structures (AoS) to a structure of arrays (SoA). Then, by blocking SoA objects, we optimize cache reuse and get sustained throughput for a range of problem sizes. We implement efficient nested threading in B-spline orbital evaluation kernels, paving the way towards enabling strong scaling of QMC simulations, resulting with performance enhancements. Finally, we employ roofline performance analysis to model the impacts of our optimizations.
An Automated Tool for MC/DC Test Data GenerationAriful Haque
Structural testing is often the most common sought criteria for exercising aspects of control flow (i.e. such as
statement, branch and path coverage). In many cases, criteria based on statement, decision and path coverage appears
sufficiently effective for testing (in terms of selecting the appropriate test cases for testing consideration) the various parts of the software implementation. In other cases involving complex predicates, criteria based on statement, branch, and path coverage appear problematic owing to the problem of masking (where one variable is “masking” the effects of other variables). Addressing this issue, this paper discusses the design and implementation of an automatic test data generation called MC/DC GEN for structural testing based on Multiple Condition/Decision Coverage (MC/DC). In doing so, this paper also highlights the possible adoption of MC/DC GEN for practical use.
