Whether the user always have GPUs in use when using this fn or is it an optional feature. The problem with implementing the scalable svd() in dml is due to the spark backend issues, otherwise there is no problem scaling w/o a local svd() function. May be we could try another algorithm for the scalable svd( ), if the present algorithm is misleading as Imran Younus pointed out. Thank you, Janardhan --089e08204f90b820570554c7c169--
