Advanced-optimized parallel sparse matrix-vector multiplication with adaptive strategies

This is an Advanced mode enhancement that automatically selects the best computational strategy based on matrix characteristics and hardware capabilities.

Arguments

• y - Output vector (will be overwritten)
• rows - Number of rows in the matrix
• indptr - Row pointer array (length = rows + 1)
• indices - Column indices array
• data - Non-zero values array
• x - Input vector

Features

• Adaptive workload balancing based on row sparsity
• Cache-aware memory access patterns
• NUMA-aware thread scheduling
• Vectorized inner loops with prefetching
