multithreaded 64bit version?

A hardware expert told me that the new multi-core machines need code that is
written to use the parallelism. Is Singular written with multi-threading?
How about a 64 bit version?

Singular supports 64bit if the CPU does, i.e.
Singular-x-x-x-ix86-x.tar.gz is 32bit, Singular-x-x-x-ix86_64-x.tar.gz is 64bit
for x86_64(amd64) CPUs.

For using several cores see parallel.lib, modstd.lib, etc.

), which uses several processes.
