Inferring Parametric Energy Consumption Functions at Different Software Levels:ISA vs. LLVM IR
The static estimation of the energy consumed by program
executions is an important challenge, which has applications in program
optimization and verification, and is instrumental in energy-aware software
development. Our objective is to estimate such energy consumption
in the form of functions on the input data sizes of programs. We have developed
a tool for experimentation with static analysis which infers such
energy functions at two levels, the instruction set architecture (ISA) and
the intermediate code (LLVM IR) levels, and re
ects it upwards to the
higher source code level. This required the development of a translation
from LLVM IR to an intermediate representation and its integration
with existing components, a translation from ISA to the same representation,
a resource analyzer, an ISA-level energy model, and a mapping
from this model to LLVM IR. The approach has been applied to programs
written in the XC language running on XCore architectures, but
is general enough to be applied to other languages. Experimental results
show that our LLVM IR level analysis is reasonably accurate (less than
6:4% average error vs. hardware measurements) and more powerful than
analysis at the ISA level. This paper provides insights into the trade-off
of precision versus analyzability at these levels

Gene Network Analysis in a Pediatric Cohort Identifies Novel Lung Function Genes
<div><p>Lung function is a heritable trait and serves as an important clinical predictor of morbidity and mortality for pulmonary conditions in adults, however, despite its importance, no studies have focused on uncovering pediatric-specific loci influencing lung function. To identify novel genetic determinants of pediatric lung function, we conducted a genome-wide association study (GWAS) of four pulmonary function traits, including FVC, FEV<sub>1</sub>, FEV<sub>1</sub>/FVC and FEF<sub>25–75%</sub> in 1556 children. Further, we carried out gene network analyses for each trait including all SNPs with a P-value of <1.0×10<sup>−3</sup> from the individual GWAS. The GWAS identified SNPs with notable trends towards association with the pulmonary function measures, including the previously described <i>INTS12</i> locus association with FEV1 (p<sub>meta</sub> = 1.41<b>×</b>10<sup>−7</sup>). The gene network analyses identified 34 networks of genes associated with pulmonary function variables in Caucasians. Of those, the glycoprotein gene network reached genome-wide significance for all four variables. P-value range p<sub>meta</sub> = 6.29×10<sup>−4</sup> - 2.80×10<sup>−8</sup> on meta-analysis. In this study, we report on specific pathways that are significantly associated with pediatric lung function at genome-wide significance. In addition, we report the first loci associated with lung function in both pediatric Caucasian and African American populations<b>.</b></p></div
