Community-driven demand creation for the use of routine viral Load Testing: a model to scale up routine viral Load Testing.
Journal of the International AIDS Society, 2017Co-Authors: Bactrin M Killingo, Trisa B Taro, Wame N MosimeAbstract:INTRODUCTION HIV treatment outcomes are dependent on the use of viral Load measurement. Despite global and national guidelines recommending the use of routine viral Load Testing, these policies alone have not translated into widespread implementation or sufficiently increased access for people living with HIV (PLHIV). Civil society and communities of PLHIV recognize the need to close this gap and to enable the scale up of routine viral Load Testing. METHODS The International Treatment Preparedness Coalition (ITPC) developed an approach to community-led demand creation for the use of routine viral Load Testing. Using this Community Demand Creation Model, implementers follow a step-wise process to capacitate and empower communities to address their most pressing needs. This includes utlizing a specific toolkit that includes conducting a baseline assessment, developing a treatment education toolkit, organizing mobilization workshops for knowledge building, provision of small grants to support advocacy work and conducting benchmark evaluations. RESULTS AND DISCUSSION The Community Demand Creation Model to increase demand for routine viral Load Testing services by PLHIV has been delivered in diverse contexts including in the sub-Saharan African, Asian, Latin American and the Caribbean regions. Between December 2015 and December 2016, ITPC trained more than 240 PLHIV activists, and disbursed US$90,000 to network partners in support of their national advocacy work. The latter efforts informed a regional, community-driven campaign calling for domestic investment in the expeditious implementation of national viral Load Testing guidelines. CONCLUSIONS HIV treatment education and community mobilization are critical components of demand creation for access to optimal HIV treatment, especially for the use of routine viral Load Testing. ITPC's Community Demand Creation Model offers a novel approach to achieving this goal.

ICSE-SEIP - Analytics-driven Load Testing: an industrial experience report on Load Testing of large-scale systems
2017 IEEE ACM 39th International Conference on Software Engineering: Software Engineering in Practice Track (ICSE-SEIP), 2017Co-Authors: Tse-hsun Chen, Zhen Ming Jiang, Ahmed E. Hassan, Mark D. Syer, Weiyi Shang, Mohamed Nasser, Parminder FloraAbstract:Assessing how large-scale software systems behave under Load is essential because many problems cannot be uncovered without executing tests of large volumes of concurrent requests. Load-related problems can directly affect the customer- perceived quality of systems and often cost companies millions of dollars. Load Testing is the standard approach for assessing how a system behaves under Load. However, designing, executing and analyzing a Load test can be very difficult due to the scale of the test (e.g., simulating millions of users and analyzing terabytes of data). Over the past decade, we have tackled many Load Testing challenges in an industrial setting. In this paper, we document the challenges that we encountered and the lessons that we learned as we addressed these challenges. We provide general guidelines for conducting Load tests using an analytics-driven approach. We also discuss open research challenges that require attention from the research community. We believe that our experience can be beneficial to practitioners and researchers who are interested in the area of Load Testing.

A Survey on Load Testing of Large-Scale Software Systems
IEEE Transactions on Software Engineering, 2015Co-Authors: Zhen Ming Jiang, Ahmed E. HassanAbstract:Many large-scale software systems must service thousands or millions of concurrent requests. These systems must be Load tested to ensure that they can function correctly under Load (i.e., the rate of the incoming requests). In this paper, we survey the state of Load Testing research and practice. We compare and contrast current techniques that are used in the three phases of a Load test: (1) designing a proper Load, (2) executing a Load test, and (3) analyzing the results of a Load test. This survey will be useful for Load Testing practitioners and software engineering researchers with interest in the Load Testing of large-scale software systems.

automated analysis of Load Testing results
International Symposium on Software Testing and Analysis, 2010Co-Authors: Zhen Ming JiangAbstract:Many software systems must be Load tested to ensure that they can scale up while maintaining functional and performance requirements. Current industrial practices for checking the results of a Load test remain ad hoc, involving high level checks. Few research efforts are devoted to the automated analysis of Load Testing results, mainly due to the limited access to large scale systems for use as case studies. Automated and systematic Load Testing analysis is going to be much needed, as many services have been offered online to an increasing number of users. This dissertation proposes automated approaches to detect functional and performance problems in a Load test by mining the recorded Load Testing data (execution logs and performance metrics). Case studies show that our approaches scale well to large enterprise systems and output high precision results that help analysts detect Load Testing problems.

ICSM - Automatic identification of Load Testing problems
2008 IEEE International Conference on Software Maintenance, 2008Co-Authors: Zhen Ming Jiang, Ahmed E. Hassan, Gilbert Hamann, Parminder FloraAbstract:Many software applications must provide services to hundreds or thousands of users concurrently. These applications must be Load tested to ensure that they can function correctly under high Load. Problems in Load Testing are due to problems in the Load environment, the Load generators, and the application under test. It is important to identify and address these problems to ensure that Load Testing results are correct and these problems are resolved. It is difficult to detect problems in a Load test due to the large amount of data which must be examined. Current industrial practice mainly involves time-consuming manual checks which, for example, grep the logs of the application for error messages. In this paper, we present an approach which mines the execution logs of an application to uncover the dominant behavior (i.e., execution sequences) for the application and flags anomalies (i.e., deviations) from the dominant behavior. Using a case study of two open source and two large enterprise software applications, we show that our approach can automatically identify problems in a Load test. Our approach flags < 0.01% of the log lines for closer analysis by domain experts. The flagged lines indicate Load Testing problems with a relatively small number of false alarms. Our approach scales well for large applications and is currently used daily in practice.

Point-of-Care HIV Viral Load Testing: an Essential Tool for a Sustainable Global HIV/AIDS Response.
Clinical Microbiology Reviews, 2019Co-Authors: Paul K. Drain, Jienchi Dorward, Andrew T. Bender, Lorraine Lillis, Francesco Marinucci, Jilian Sacks, Anna Bershteyn, David S. Boyle, Jonathan D. Posner, Nigel GarrettAbstract:The global public health community has set ambitious treatment targets to end the HIV/AIDS pandemic. With the notable absence of a cure, the goal of HIV treatment is to achieve sustained suppression of an HIV viral Load, which allows for immunological recovery and reduces the risk of onward HIV transmission. Monitoring HIV viral Load in people living with HIV is therefore central to maintaining effective individual antiretroviral therapy as well as monitoring progress toward achieving population targets for viral suppression. The capacity for laboratory-based HIV viral Load Testing has increased rapidly in low- and middle-income countries, but implementation of universal viral Load monitoring is still hindered by several barriers and delays. New devices for point-of-care HIV viral Load Testing may be used near patients to improve HIV management by reducing the turnaround time for clinical test results. The implementation of near-patient Testing using these new and emerging technologies may be an essential tool for ensuring a sustainable response that will ultimately enable an end to the HIV/AIDS pandemic. In this report, we review the current and emerging technology, the evidence for decentralized viral Load monitoring by non-laboratory health care workers, and the additional considerations for expanding point-of-care HIV viral Load Testing.
