High functionality Computing (HPC) is still a driving force that gives large potentials and advantages for technological know-how and society. besides the fact that, a profound realizing of the computational issues and really good software program is required to reach at potent and effective simulations. committed software program instruments are vital components of the HPC software program panorama, and help software builders. even supposing a device is by way of definition now not part of an program, yet quite a supplemental piece of software program, it will probably make a primary distinction through the improvement of an software. Such instruments reduction software builders within the context of debugging, functionality research, and code optimization, and hence make an incredible contribution to the improvement of sturdy and effective parallel software program. This ebook introduces a variety of the instruments awarded and mentioned on the ninth foreign Parallel instruments Workshop held in Dresden, Germany, September 2-3, 2015, which provided a longtime discussion board for discussing the newest advances in parallel tools.

In this paper we present our efforts to analyze and optimize the RNA-Seq assembler Trinity [4]. Trinity is a software tool that was developed for accurate de novo reconstruction of transcriptomes from RNA-Seq data.

We have listed suitable event sets to identify the bandwidth saturation, load imbalance, and false sharing patterns with HPM on the Intel Haswell architecture. , the sharing of cache lines at the L3 level. Moreover, a more fine-grained and correct filtering of instructions would be helpful for pattern-based performance analysis. Using a selection of streaming loop kernels we found the error for the bandwidthrelated events to be small on average (−1 % . . +2 %), with a maximum undercounting of about −6 % for the L3 traffic.
