description = """
COSMA is a parallel, high-performance, GPU-accelerated, matrix-matrix 
multiplication algorithm that is communication-optimal for all combinations 
of matrix dimensions, number of processors and memory sizes, without the 
need for any parameter tuning. The key idea behind COSMA is to first derive 
a tight optimal sequential schedule and only then parallelize it, preserving 
I/O optimality between processes.
