Hardware accelerators have changed the HPC landscape as they open a potential route to exascale computing.At the same time they also complicate the tasl of application development since they introduce another level of parallelism and, thus, complexity. Performance tool support to aid the developer will be a necessity. While profiling is offered by the accelerator vendors, tracing tools can also adopt hardware accelerators.A number of challenges for data acquisition and visualization and their solutions are presented in this paper. © Springer-Verlag Berlin Heidelberg 2012.
