My apologies in advance if this has already been addressed, but I haven't found the answer elsewhere.
I have a powerful workstation with dual Xeons with 16 cores each. dual booting Windows 7 and Ubuntu Linux. Running on the Windows partition I have used two commercial solutions as well as allowing Rosetta@Home to utilize the system a few hours each night. Modeling done on all three solutions pegs all 32 processing cores at 100% and the completion times on high quality homology modeling is very low (around 10 hours).
However, I don't find the same running on Ubuntu 14.04 LTS. The most dramatic contrast is Rosetta@home... running on Windows 7, as I mentioned, all 32 processors are pegged and I have contributed several million credits to the project in a short time. When I run it on Linux, it uses only one processor and the performance difference is predictably deplorable.
I know homology modeling from the standpoint of the generation of a single model is not inherently improved by multithreading. However, running a job where hundreds of models are generated obviously is.
I am not a Linux pro, and honestly, I have no desire to be. I just want to get my work done. I need Rosetta generated models.
Can someone please give me a step by step for getting Rosetta setup to fully exploit the processing power of my machine? I've tried several iterations, but there are so many pacakges, versions, path variables, etc...
Thank you kindly!
