Why does this mean no further latency penalties? The recomputation algorithm is unlikely to encounter the same missing row again before the row has to be thrown out of the algorithm's temporary storage. And the row's columns are still needed in reverse order of computation, so the first-computed column, which has to be stored, is the last-needed one. Am I missing something? Thanks! Alexander
