D. Why do file permissions change when files are copied to research storage home folders and/or project spaces?

File transfer programs, including the Mac Finder and Windows Explorer, try to do  the best job possible matching permission when files are copies over. But since the operating systems typically are different between the source (your computer) and the destination (the storage on the compute grid), the programs attempt to match as best as possible.

  • If the compute grid is busy, there many not be enough RAM or CPUs on any of the compute nodes to run your application. See...
