A cache memory stores 2^J-byte cache lines and includes an array of 2^N sets each holding tags each X bits, an input receives a Q-bit memory address, MA[(Q−1):0], having: a tag MA[(Q−1):(Q−X)] and an index MA[(Q−X−1):J]. Q is an integer at least (N+J+X−1). In a first mode: set selection logic selects one set using the index and LSB of the tag; comparison logic compares all but LSB of the tag with all but LSB of each tag in the selected set and indicates a hit if a match; otherwise allocation logic allocates into the selected set. In a second mode: the set selection logic selects two sets using the index; the comparison logic compares the tag with each tag in the selected two sets and indicates a hit if a match; and otherwise allocates into one set of the two selected sets.

Computer-implemented systems and computer-implemented methods include the following. A request to train a machine-learning (ML) model is received at a training broker. Anonymized data for training the model is obtained by the training broker from each individual data source of a plurality of data sources. The anonymized data is accessed through a data science schema being provided by anonymization of sensitive information of production data from each individual data source. Access to the anonymized data is provided to a data vendor for training the ML model using the anonymized data.
