A mentor and friend, from whom I have learnt the vital skill of disciplined critical thinking

Foremost, I would like to express my deepest thanks to my two supervisors, Professor Phil Trinder and Dr Patrick Maier. Their patience, encouragement, and immense knowledge were key motivations throughout my PhD. They carry out their research with an objective and principled approach to computer science. They persuasively conveyed an interest in my work, and I am grateful for my inclusion in their HPC-GAP project.

Phil has been my supervisor and guiding beacon through four years of computer science MEng and PhD research. I am truly thankful for his steadfast integrity, and selfless dedication to both my personal and academic development. I cannot think of a better supervisor to have. Patrick is a mentor and friend, from whom I have learnt the vital skill of disciplined critical thinking. His forensic scrutiny of my technical writing has been invaluable. He has always found the time to propose consistently excellent improvements. I owe a great debt of gratitude to Phil and Patrick.

I would like to thank Professor Greg Michaelson for offering thorough and excellent feedback on an earlier version of this thesis. In addition, a thank you to Dr Gudmund Grov. Gudmund gave feedback on Chapter 4 of this thesis, and suggested generality improvements to my model checking abstraction of HdpH-RS.

A special mention for Dr Edsko de Vries of Well Typed, for our insightful and detailed discussions about network transport design. Furthermore, Edsko engineered the network abstraction layer on which the fault detecting component of HdpH-RS is built.

I thank the computing officers at Heriot-Watt University and the Edinburgh Parallel Computing Centre for their support and hardware access for the performance evaluation of HdpH-RS.

For my son, who because of who he is, made me who I am

This thesis would not exist without the parents and practitioners who agreed to share their stories with me – a heartfelt thanks to each of you for risking your story with me!

I also want to thank the many people who have accompanied me on different parts of the journey:

Judith Good and Susie Scott who have helped me to play by the rules – thank you for your patience and persistence and for keeping me on track;

Lou McGill, my critical friend;

Friends and colleagues at the University of Sussex, too numerous to mention by name, but the folk who have met for breakfast, or coffee, or cream tea;

The network of research students who inhabit Twitter and #phdchat, the folk who have so often picked me up and supported me when I’ve threatened to jump ship;

My colleagues at The Open University, some of whom commented on initial drafts and diagrams, and my managers who supported my application for financial support.

And most of all thanks to my husband, friend, confidant and proof reader – thank you Gordon for putting up with all the mood swings – and to my son, who because of who he is, got me involved in the special needs domain.

A PhD was never part of my life plan – they were for ‘clever’ people. A chance encounter and a foolish question started me on this journey. Thinking back, the journey didn’t start there, but much further back with other chance encounters and people who believed in me, in particular Colin Archer, my manager, mentor and friend for many years when I was a young social worker, but also other friends and colleagues who have share part of my life journey with me, the names of whom are now lost in the mists of time.

The path to becoming a doctor is littered with distractions. I’d like to thank those distractions for making me the person I am

I would like to thank many people who have helped me through the completion of this dissertation. The first is my advisor, Steve Harrison, who is captivating, honest, and the true embodiment of a mentor. In combination with the mentorship of my advisor, I am blessed to work with dynamic and intelligent committee members Dr. Dennis Kafura, Dr. D. Scott McCrickard, Dr. Enid Montague, and Dr. Deborah Tatar. I would also like to thank the Computer Science Department at Virginia Tech and ADVANCE NSF for funding my time at Virginia Tech. Peggy Layne, who worked with me at ADVANCE was a brilliant and insightful mentor Additionally the mentorship of Victoria Bellotti, Oliver Brdiczka, Tara Matthews, and Tom Moran was instrumental to me during my internships, and their continued advice is invaluable.

This work was not completed in a vacuum. I worked with many brilliant students who broadened the value of the work: Laura Agnich, Monika Akbar, Aubrey Baker, Stacy Branham, Tom Dehart, Zalia Shams, and Edgardo Vega. Working with each of these students has been a gift that went much further than just completing work that needed to be done. Working with them expanded the value of the work. I appreciated each and every minute they spent with the data and (more important) with me.

I am thankful for and would like to acknowledge many others who helped me along the way: my father, Richard Hobby, who proofed many of my papers; my friends and family for late night phone calls; and my colleagues for bouncing ideas with me. This includes, but is not limited to Julia Hobby, Rich Hobby, Laura Harty, Elaine Hobby, Jason Lee, Shahtab Wahid, Tejinder Judge, Rishi Pande, Ross Goddard, Bobby Beaton, Sarah Peck, Kim Gausepohl, Kelly Meredith, Michael Evans, Jamika Burge, Manas Tungare, Ben Congleton, Pardha Pyla, Manuel Perez, Megan Beavers, Jocelyn Casto, Uma Murthy, Mara de Silva, Jon Howarth, Theresa Blanchard-Klunk, Sirong Lin, Joon Lee, Susan Wyche, Promita Chakraborty, Michael Stewart, the Garcoskis, Ben Hanrahan, Yeong-Tay Sun, Caitlin Sadowski, Alexandra Holloway, and Rex Hartson.

I am beyond grateful to all of my participants who were not paid to participate in the project. The people who participated in my study were generous with their time in a way that I can never repay.

Cameron Vega, my son, thank you for reorienting my life.

There are many neglected people and groups that are involved in the completion of a Ph.D. that I would like to acknowledge. I would like to thank Meg Kurdziolek for starting a dissertation writing group. I would like to thank all the amazing women in the front office in the Computer Science Department who calm me down when I express a complete lack of knowledge about paperwork, protocol, and procedures. I would like to thank my music library for the writing trances that helped complete each chapter. The group Horse Feathers has been specifically amazing. I would like to thank my university library for access to the many books and articles that influences how I think. The also sometimes purchased books that were relevant to my dissertation. I’d like to thank all the people who provided feedback when I presented posters and talked about my research at conferences. I’ve also received numerous scholarships, which have allowed me to travel to said conferences. Thanks for supporting a poor graduate student.

Being a woman in computer science has, in part, made me the woman I am. I’d like to thank the Anita Borg Institute and all the women who have been, and will continue to be, in the Virginia Tech Association for Women in Computing for the continual support. To complement that last comment, last, thanks to all the men in computer science who gave me explicit and implicit warnings that, as a woman, I couldn’t cut it. You enrage my inner feminist (read: “bitch”). Thanks for making me push myself harder.

The path to becoming a doctor is littered with distractions. I’d like to thank those distractions for making me the person I am.

Princess Nisa, you really are a little princess (and now it’s written in the Trinity College Library, so it must be true!)

Kenneth Henry – thanks for being a great supervisor and a good sport. Andrew ‘brain the size of a planet’ Lloyd, my mentor – Thank You For Sharing. None of it would have been the same if I wasn’t in such a positive, encouraging environment with the rest of the Wolfe Cubs. Karsten working side-by-side with you for the stuff of Chapter 4 was a great experience. I hope all my future collaborations are as fruitful and good-natured. Cathal and Lucy, the predecessors, thanks for showing me that it can be done (and how to do it!). Avril, thanks for always being willing to direct your insightful intellect towards my problems. Simon thanks for your willingness to help with anything. All of you, and the new folks, Antoinette, Kevin, and Sean, thanks for being so understanding and helpful while I’ve been writing up. Thanks also to Denis Shields for the suggestion of the block overlap simulations in Chapter 4, and all the members of the Tuesday lunchtime group for helpful comments over the years.

My family and friends deserve special thanks for supporting me in various ways. Mum – thanks for Friday lunchtimes in Dunnes & Crescenzi’s and ‘Friday Presents’. Dad – the running total is 2135 Brownie Points, a few more and you’ll have enough for a toaster. Emer – those cinema outings helped me stay relaxed, thanks. Wendy, my adopted Scottish sister and bestest friend – thanks for always dropping everything at a moment’s notice and making everything so much fun. Thanks to Gianluca for lots of emotional support and for help with footnotes and other LATEX oddities. Thanks to my ‘roomies’, Lisa and Emma Jane, for being great pals. Princess Nisa, you really are a little princess (and now it’s written in the Trinity College Library, so it must be true!). The girls on the rugby team definitely helped me keep my sanity by allowing me to vent my frustrations by tipping them upside-down in the mud of College Park … thanks!
