The paper, "Accelerating Phylogenetic Inference on GPUs: an OpenACC and CUDA comparison" by University of Barcelona and Intel Barcelona Research Center claim near-CUDA performance for OpenACC - within 10% - that can be achieved when accelerating a Phylogenetic Tree code based on the popular MrBayes Markov chain Monte Carlo (MCMC) package. Comparing with state-of-art … [Read more...]
MSI WS60 Mobile Workstation – Awesome CUDA-Capable, Linux, and Window Mobility
The recently released MSI mobile workstation (WS60 20 OJ 3K-004US) provides a no-compromise laptop for those who wish a thin-and-light desktop replacement at work and when traveling. This device is now my work machine of choice (that relegated a wonderful HP Z800 workstation to a remotely accessed resource). I have found that the WS60 provides a well-designed and … [Read more...]
