Dear gretl users,
I have a three laptops (some of them are about 5 years old but have fast CPUs
implemented) and a desktop computer available, and was thinking to set up a
small-scale cluster.
It seems to me that the MPI interface which gretl supports is just designed
for such a task. Is this correct?
Yes.
Does anybody have some experience with it?
Some. In order to make the most of it, keep in mind that the most
stringent constraint on performance is the ethernet connection. So, you're
going to have good results as far as you manage to split the workload
between processes in such a way to minimise the amount of data they have
to trade between one another. Sometimes it's relatively simple to do so,
sometimes it requires some ingenuity.
