             Summary: Add support for aggregate unary operations on GPU
                 Key: SYSTEMML-1038
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1038
             Project: SystemML
          Issue Type: Sub-task
            Reporter: Niketan Pansare


1. Update UnaryOp to enable GPU for these instructions.
2. Add AggregateUnaryGPUInstruction and invoke kernels corresponding to https://github.com/apache/incubator-systemml/blob/master/src/main/java/org/apache/sysml/runtime/matrix/data/MatrixBlock.java#L4451

Note nrow, ncol and length should always be a CP instruction. Also, we can break this into subtasks for sparse if necessary.

The opcodes related to this tasks are: uak+, uark+, uack+, uasqk+, uarsqk+, uacsqk+, uamean, uarmean, uacmean, uavar, uarvar, uacvar, uamax, uarmax, uarimax, uacmax, uamin, uarmin, uarimin, uacmin, ua+, uar+, uac+, ua*, uatrace, uaktrace and the operations of these are (with/without kahan) sum, trace, rowsum, colsum, sum of squares, row sum of squares, col sum of squares, cumsum, cumprod, cummin, cummax, min, max, min_index, max_index, mean, variance and product.

[~nakul02] This is a mega-task. Hopefully we can generalize our kernel implementation to make this easier.
