1 DNA and RNA base pairing is slightly different, since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. 2  Uracil differs from thymine in that it lacks a methyl group on its ring.

I run a bunch of heavy user space processes on a powerful Xeon machine (32 virtual processors according to /proc/cpuinfo). The CPU load is normally around 30 and the machine feel responsive, but later on a few more user space processes are forked and they allocate lots of memory and perform CPU intensive calculations. At that time the load increases to about 60-150 and the machine is on its knees.
