I remember reading some time back that on a pentium the difference between a pentium in HLT vs. running was about 2-3 watts vs. 15-20 watts. Does anyone know the difference for today's CPU's? P-III/P-IV or other archs? How about the difference when calling the BIOS power-save feature? With the threat of rolling blackouts here in CA, I was wondering what the power consumption might be of a 100,000 or 1,000,000 CPU's in HLT vs. doing complex mathematical computation? Separately -- Parallel Make's ---------- =============== So, just about anyone I know uses make -j X [-l Y] bzImage modules, but I noticed that make modules_install isn't parallel safe in 2.4 -- since it takes much longer than the old, it would make sense to want to run it in parallel as well, but it has a delete-old, <multiple sub-dirs>, index-new for deps. Those "3" steps can't be done in parallel safely. Was this intentional or would a 'fix' be desired? Is it the intention of the Makefile maintainers to allow a parallel or distributed make? I know for me it makes a noticable difference even on a 1 CPU machine (CPU overlap with disk I/O), and with multi CPU machines, it's even more noticable. Is a make of the kernel and/or the modules designed to be parallel safe? Is it something I should 'rely' on? If it isn't, should it be? -l -- Linda A Walsh | Trust Technology, Core Linux, SGI [EMAIL PROTECTED] | Voice: (650) 933-5338 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
