No, it's not relevant to PETSc library functionality, but applications are welcome to use it. > How does a single Blue Gene CPU compare to a Xeon? For PETSc sparse matrix-vector and vector kernels, memory bandwidth tells 90% of the story. Some applications have other parts of their code that do a lot of flops. Note that the vectorization primitives are different between BG and Intel. > Does your PETSc code scale well on BGQ? > BG/Q is probably the easiest architecture available for this. -------------- next part -------------- An HTML attachment was scrubbed...
