+Mach was originally designed to run on SMPs. Later, it was extended to be a distributed OS. A group of workstations with Mach can act as a single powerful SMP. Thus, Mach is also called a Single System Image (SSI). Mach microkernel provides a good infrastructure for distributed computing, including thread migration, inter-thread communition (both locally and remotely), load balancing and fault-tolerance. Hurd, thus, has great potential for distributed computing. Before further development information is available, let's see a related project for Linux kernels, OpenMosix. You can reach it at:

+<http://www.openmosix.org> <http://openmosix.sourceforge.net> <http://sourceforge.net/projects/openmosix>
+
+Openmosix makes patches to various versions of Linux kernels to make them "distributedly-enabled". However, since Linux kernel is monolithic, patches should be updated with each new version of kernel. That can be a nightmare, with regard to the pace at which Linux kernels are being developed.
+
+By contrast, distributed computing can be more easily implemented in Hurd as various servers. Efforts will be taken to make it happen.
