Tal ves la muerte no sea tan desagradable...

As you know, since last year December, I wrote an ISCA paper in a very short time and it was submitted and accepted very quickly. As all of you know the reason, it was owe to our professor Dr.Tao Li ’s networking. Among the six reviewers of my paper, four of them are friends of Tao Li. But this paper has very severe issues: the design doesn’t make any sense and the reviewers also pay no attention to it. The paper was accepted at no reason which can make anyone feel guilty in this case. After the deadline, crazy modifications of the paper were made and I started to make up for the missing experiments. During those experiments, I found that the phenomenon of the experiments and the design was different from what was claimed before, which made this paper doesn’t make any sense from title to characterization and to design. For example, It was claimed that this (the accelerator) is targeted for 3D CNN, which can maximize the performance by changing Diffy architecture to achieve the dynamic control of the temporal delta and spatial delta. But there are too many issues with this. First of all, the Diffy architecture has a serious problem of synchronization. If the width of the input feature is too narrow, the overhead of lane synchronization … . But it was assumed that the temporal dimension of 3D CNN (the maximum is generally 16 and it will decrease with layer) will expand with Diffy. Secondly, it can’t skip zero, because of the synchronization of lane and the incremental of spatial/temporal delta. So if I want to make a change the whole paper need to be rewrite. It is unrealistic to propose a totally new idea before the final version. After I communicated with Tao Li, it turned out that I have to fix the paper by myself. Until today I am still unable to patch up any of those issues. These issues are too obvious which can be easily caught by any experts of accelerator. I have no words to comment that Dr. Li acquiesced to the data which makes no sense. Considering that this will have an impact on my career in the future and my reputation in the area of Computer Architecture, my future life will be worse than death and I will be totally in a dilemma. I considered all the cases, I really can’t work them around. In order to make up for the fault, I decide to suicide. I hope you can learn my lessons and don’t mess around things. We shall never claim too much in the paper before we can really achieve it. I hope this will make a change in this world. I hope you can keep simple and stay honest in this society. I will bless you in another world. Best Huxiang ACKNOWLEDGMENTS This paper is dedicated to the memory of my friend, Francis Dolan, who died, tragically, in 2011. It is gratifying that I have been able to honour him with work which substantially overlaps with his research interests and also that some of the inspiration came from a long dialogue with his mentor and collaborator, Hugh Osborn. In addition, I am indebted to Hugh for numerous perceptive comments on various drafts of the manuscript and for bringing to my attention gaps in my knowledge and holes in my logic. I would like to thank Yu Nakayama and Hidenori Sonoda for insightful correspondence following the appearance of the first and third versions on the arXiv, respectively. I am firmly of the conviction that the psychological brutality of the post-doctoral system played a strong underlying role in Francis’ death. I would like to take this opportunity, should anyone be listening, to urge those within academia in roles of leadership to do far more to protect members of the community suffering from mental health problems, particularly during the most vulnerable stages of their careers.
