################################## -t 8 means 8 threads. depending on the ec2 instance you can choose more threads
###  V 448 means SSE1/2/3 support. A14 means x86SSE364SSE2 architecture. check the documentation for more information
### if you run smaller instances you may get 32 bit machines. in this case you need to build -b 32, too and install the
### appropriate version on run time.
