Dear Derek, Thank you very much for your response. I am really glad that libmesh can scale to 12,000 cores now, and I am thinking to give it a shot on my research. About half a year ago, some people told me that libmesh can only scale to hundreds of processors on a cluster since libmesh stores s

We've achieved great scaling out to 12,000 cores with ~250 million dofs. At that size though things do get more difficult. You have to use ParallelMesh along with a parallel mesh / solution format (like NEMESIS). It is definitely possible to go further... But that's the largest set of procs we h

Dear all, I want to know some information on the scalability of Libmesh. How many processors has Libmesh been scaled to? Is there any document on how the libmesh work on some supercomter, such as Blue Gene? Libmesh appears to be very good, while the scalability is one of my important concerns.
