Vivado 2012.2 and later tools support multi-threading by default. The default number of cores used will be 4, but the tools will not use more threads than the number of cores on the machine (i.e., a dual core machine will use two cores). This applies to both place and route.
The TCL parameter for overriding this behavior is:
set_param general.maxThreads 1
