Re: [Gems-users] Having trouble getting LogTM running

[Dan Gibson <degibson@xxxxxxxx>]

Installation of the OS can take a LONG LONG time to run. Having 32 
processors and 64 GB of memory will only slow things down. If you're 
concerned about excess runtime, I'd recommend trying to make a 2-8 
processor checkpoint with 4 GB of RAM (I believe the LogTM papers used 
machines with 4 GB, though an author might correct me on that).
Regards,
Dan
