Hi! I'm trying mpiblast for the first time, and I'm testing it in a small (hmm, indeed very small) cluster. Actually, you wouldn't call it a cluster :) I have two machines. A master node, and a slave node. I have installed mpich-1.2.5 and mpiblast-1.2.0 on both. All the tests I've performed (from reading the docs) pass. However, all the jobs run on the slave. The master just sits down quietly waiting for the slave to finish with one segment, before feeding the next. I suppose that this is the desired behaviour when you have a big cluster -- you'll want to use the master node for managing the nodes, and not run any job. But what about small clusters of workstations? I would want the jobs to be run also by the master host. Is this impossible to do with the current state of the tools? I imagine that for a small number of nodes, and if the master is not managing anything else (sge or other mpi jobs), it should be possible to run blast jobs on the master without affecting its ability to manage the slaves. Am i right here? Thanks in advance for any tip/suggestion, Fernan -- F e r n a n A g u e r o http://genoma.unsam.edu.ar/~fernan
