Editor’s Note


Pages: pp. 1-3

The IEEE Transactions on Parallel and Distributed Systems ( TPDS) has completed 20 years of publication. Once again, congratulations on the 20th anniversary! “This event comes at a time where the field of parallel and distributed systems has moved from an interesting niche to the center of the computing universe. Internet systems, multicore, high-performance computing technology, international collaboratories....will provide TPDS topics for years to come” (Rudi Eigenmann).

Over two decades, TPDS has come a long way and is now the flagship journal in the field of parallel and distributed processing. A large measure of credit for this accomplishment goes to founders Tze-yun Feng, Duncan Lawrie, John Stankovic, Pen-Chung Yew, and Laxmi Bhuyan, the outgoing Editor-in-Chief, for their excellent stewardship of the journal in their roles as Editors-in-Chief. I would like to congratulate Laxmi for an excellent job under his leadership over the past four years and to express our gratitude for the time and effort he put into TPDS. In particular, Laxmi managed to reduce the time for the first response to authors to an average of four months, which is competitive with the relevant top conferences. TPDS offers authors the advantage of responding to reviewers and submitting revised articles, which is not available in the case of rejection of conference submissions. I am truly privileged and honored to carry this tradition of excellence with TPDS into the third decade.

The 20th anniversary is also an opportunity for special thanks to past contributors to TPDS’s success. The list is too long to mention everyone, but perhaps the credit should be given in the order decided by the number of papers (co)authored for TPDS. Using data provided by Scopus (in October 2009), which certainly contain errors (for which I apologize), here is a sorted list of those with at least four papers in TPDS: S.

Contributions to the citation count for TPDS are also important as the related impact factor is normally (and arguably) used as a single measure of journal prestige. Here is the list of the top 10 TPDS papers, by their citation counts, in Scopus (S) or Google Scholar (G), as of October 2009:

Being published in TPDS always provided the ultimate proof of the quality of research contributions and the opportunity to attract attention to articles. It also served as a catapult for new research areas such as wireless ad hoc and sensor networks and mobile computing, leading to more new specialized IEEE journals. TPDS was also nimble in responding to current developments in the field. Special issues on specific topics have, to some extent, served this purpose. They trigger more submissions in emerging areas, and contribute to a lot of citations and raising TPDS’s impact factor (especially during Pen-Chung’s and Laxmi’s leaderships). Parallel and distributed systems have proliferated over the past two decades and now impact all aspects of computing. TPDS will continue to take the lead in conveying the excitement of such developments to the field and stimulating further research. I believe it has become a very important resource in our research community, and will continue to do so “with the emergence of multicore technology and revitalization of parallel computing research” (Yi Pan). Its continued success very much hinges on the support of its readers, authors, and reviewers, as well as the editorial board and the publication staff. I look forward to working with all of these contributors to maintain TPDS as the premier, high-quality, and archival journal for the rapidly changing field of parallel and distributed processing.

My predecessors have already made important steps in raising TPDS to the current level. I will make an attempt to improve the scientific quality and the impact of published articles by increasing their readability. That is, presentation is as important as the technical content, to allow readers to process contributions in minimal time, therefore increasing the likelihood of their use and subsequent citations. I will contribute in this direction by publishing my own article “How to Write Research Articles in Computing and Related Engineering Disciplines” as the editorial in the next issue of TPDS. My arguable advice will hopefully help authors, even beyond writing, well into their research practices, and I welcome any criticism, comments, and additions to its content and presentation practice.

I would like to thank some of the editorial board members who retired in December 2009. Associate Editors Sajal Das, Mohamed Ould Khaoua, Yi Pan, and Cyrus Shahabi have successfully completed their terms. It is also time to thank our dedicated Associate Editor-in-Chief, Xiaodong Zhang, for his commitment and effort during his tenure. Stephan Olariu from Old Dominion University will take charge as the new Associate Editor-in-Chief. He is an author with a record number of 36 articles in TPDS and I am honored to select him to become the Associate Editor-in-Chief.
