A user has been offered a research position that requires knowledge of specific computing architectures and is seeking book recommendations. For those working with a Fermi-Cluster, "GPU Computing Gems Emerald Edition" is suggested as a valuable resource. In contrast, for non-homogeneous CPU clusters, there is less clarity on recommendations, although OpenCL is mentioned as a potential solution for handling such architectures, with the caveat that it may require adjustments to initialization options in the code. Overall, the discussion emphasizes the importance of understanding the specific architecture involved in the research position to select appropriate resources.
