Toward optimised skeletons for heterogeneous parallel architecture with performance cost model
High performance architectures are increasingly heterogeneous with shared and
distributed memory components, and accelerators like GPUs. Programming such
architectures is complicated and performance portability is a major issue as the
architectures evolve. This thesis explores the potential for algorithmic skeletons
integrating a dynamically parametrised static cost model, to deliver portable
performance for mostly regular data parallel programs on heterogeneous archi-
tectures.
The rst contribution of this thesis is to address the challenges of program-
ming heterogeneous architectures by providing two skeleton-based programming
libraries: i.e. HWSkel for heterogeneous multicore clusters and GPU-HWSkel
that enables GPUs to be exploited as general purpose multi-processor devices.
Both libraries provide heterogeneous data parallel algorithmic skeletons including
hMap, hMapAll, hReduce, hMapReduce, and hMapReduceAll.
The second contribution is the development of cost models for workload dis-
tribution. First, we construct an architectural cost model (CM1) to optimise
overall processing time for HWSkel heterogeneous skeletons on a heterogeneous
system composed of networks of arbitrary numbers of nodes, each with an ar-
bitrary number of cores sharing arbitrary amounts of memory. The cost model
characterises the components of the architecture by the number of cores, clock
speed, and crucially the size of the L2 cache. Second, we extend the HWSkel cost
model (CM1) to account for GPU performance. The extended cost model (CM2)
is used in the GPU-HWSkel library to automatically nd a good distribution
for both a single heterogeneous multicore/GPU node, and clusters of heteroge-
neous multicore/GPU nodes. Experiments are carried out on three heterogeneous
multicore clusters, four heterogeneous multicore/GPU clusters, and three single
heterogeneous multicore/GPU nodes. The results of experimental evaluations for
four data parallel benchmarks, i.e. sumEuler, Image matching, Fibonacci, and
Matrix Multiplication, show that our combined heterogeneous skeletons and cost
models can make good use of resources in heterogeneous systems. Moreover using
cores together with a GPU in the same host can deliver good performance either
on a single node or on multiple node architectures
Study of occurrence of childhood hypertension in school going children attending pediatrics OPD in Moradabad city
Background: In developed countries, childhood hypertension is a proven indicator of adult hypertension and organ damage and is estimated to be great concern. This study was conducted to assess the occurrence of childhood hypertension in school going children attending pediatrics OPD.Methods: An observational study was performed at TMMC and RC among 500 school going children attending pediatrics OPD in TMMC and RC over a period of 1 year. Socio-demographic variables including age, gender, family history of hypertension, parental smoking habits were recorded in a proforma. Dietary habits including consumption of junk food, fruits and daily calorie intake was evaluated utilizing number of times diet intake questionnaire and 24 hour recall method. Height was measured by stadiometer with candidate posing in bare feet. Weight assessment was done with bare footed and candidate clad in light clothing with weighing instrument of electronic type rounded to nearest unit.Results: Elevated blood pressure and hypertension was reported among 9.4% and 6.8% of the subjects respectively. High blood pressure was significantly associated with presence of family history, stress and lack daily physical activity. Chances of elevated blood pressure and hypertension increase along with the increase in subject height, weight and BMI.Conclusions: Performing the BP measurements in routine consultations becomes essential for diagnosis and early intervention
Design and analysis of a novel low PDP full adder cell
This paper, presents a new full-swing low power high performance full adder circuit in CMOS technology. It benefits from a full swing XOR-XNOR module with no feedback transistors, which decreases delay and power consumption. In addition, high driving capability of COUT module and low PDP design of SUM module contribute to more PDP reduction in cascaded mode. In order to have accurate analysis, the new circuit along with several well-known full adders from literature have been modeled and compared with CADENCE. Comparison consists of power consumption, performance, PDP, and area. Results show that there are improvements in both power consumption and performance. This design trades area with low PDP
A needs assessment of employee wellness on a college campus.
The purpose of this research project was to conduct a needs assessment to determine employee interest, preference, and current health status among faculty and staff on a college campus. A review of the literature showed employers should assess needs and preferences of employees to increase participation in Worksite Health Promotion Programs (WHPPs). For the current study, Biometric Screenings (BS) were conducted to establish faculty and staff current health status prior. In addition, the American College Health Association-National Faculty and Staff Health Assessment (ACHA-NFSHA) was sent out to 1,415 faculty and staff at the university to assess interests, preferences, and health status. The results of the needs assessment showed 71.6% of participants considered themselves to be good or very good in overall general health and 78.0% stated it was important or very important to model health and wellness behavior to students. The number one barrier to participation in employee wellness programs was time management. Both the survey and biometric screenings indicated a need for diabetes and heart health education programs to be offered on campus to employees. In conclusion, multi-component needs assessments are important tools for accurately identifying needs, preferences, and health status of university employees

Racial/Ethnic Differences in Religious Congregation-based Social Service Delivery Efforts
The current study utilizes Swidler\u27s (1986) cultural toolkit theory to explain racial/ethnic differences in American religious congregations\u27 provision of social service programs. This study suggests that black Americans\u27 reliance upon structural tools to assess poverty contributes to their congregations being more heavily involved than majority white congregations in the provision of social services that attempt to make a longer-term impact on community life (i.e. academic tutoring and job training). In contrast, white Americans\u27 greater reliance upon individualistic tools to understand poverty arguably contributes to their congregations being more heavily involved in the provision of programs that have a shorter- term impact on community life (i.e. food, thrift, and shelter). While majority Latino congregations are less likely than are black congregations to provide longer-term impacting programs only, majority Asian congregations tend to be less heavily involved in the provision of both longer and shorter term impacting programs
Racial/Ethnic Differences in the Provision of Health-related Programs among American Religious Congregations
Using national data from the Faith Communities Today 2000 survey, the current study builds upon Lincoln and Mamiya\u27s (1990) argument of the civically active Black Church. Originally used to assess the relative activism of Black and White congregations, the current study suggests that Black congregations are more likely to provide health programs than are predominantly White, Hispanic and Asian congregations. The greater involvement of Black congregations in the provision of health programs likely has much to do with the historical and continued cultural, spiritual, and political role that churches play in Black communities
