Dear list, Does the snowfall package work under Windows 7? Recently I upgraded from Windows Vista to Windows 7, and at the same time upgraded R from 2.8.1 to 2.10. On my machine (Intel i7 based) snowfall worked perfectly on my previous installation, but after the upgrade the same scripts do not work. When I issue e.g. sfInit(parallel=T, cpus=2) # (or 'cpus=7', which I often used before as the processor has 8 cores) R appears to be working, but uses no processor power. It stays like that (have waited many minutes) until I interrupt by hitting the Esc-key. After that it has not initiated parallel computing. Is snowfall incompatible with Windows 7 or is there something I can do? /Ola [[alternative HTML version deleted]]
