Hi all, I'm a graduate student in Computer Sciences, and as a part of my studies I need to run numerical simulations (large amounts of memory, taking a long time to run - sometimes hours, sometimes days). My current computer setup is an MBA 13" at home and a non-Retina 15" MBP supplied by the university. Until recently (long story), we've had a set of servers to use for running experiments. However, this is no longer the case. As a result, I'm left needing a replacement. My MBP has an i7 processor (4 cores) with 16GB of memory. My plan is to convert my MBP into an "easily luggable" compute node, which can sit on my desk in the office in clamshell mode (connected to a monitor) and crank out experiments. The reason we've usually not ran experiments on our laptops directly is that they've often had to run for many hours or many days, so it's been more convenient to have a remote machine run them. All of my programming and other miscellaneous stuff can be then done on the MBA, and I can access the MBP over ssh. If I want to work on the weekends, or on the holidays I can then bring the MBP home with me. Now, assuming the MBP is powerful enough to run my experiments (I think it should be), is there any problem with running the MBP in this manner (lid closed, high CPU/GPU usage for hours on end)? Thanks.
