Two new file systems will be cross-mounted between yukon, chilkoot, and the ARSC network of SGI visualization hosts. This will create new opportunities for yukon users. We have also been contacting all users whose jobs have been checkpointed. As the system has proven very reliable, this is no longer deemed necessary. We will also continue to checkpoint jobs at other, unscheduled, times, depending on the system load.
Many users think parallel processing is complex.
Well, getting all those processors to cooperate isn't simple and it does require more effort than serial programming. However as with any complex activity, it is often a good idea to break down the complexity into simpler parts. Typically, the user has a lot of very similar items of work to do which don't require any interaction between them. The code below demonstrates a trivial example of this, where each processor reads and writes to its own files without any interaction with others. All processors read a common parameters file.
