Currently the svd implementation in mllib calls the dense matrix svd in breeze, which has a limitation of fitting n^2 Gram matrix entries in memory (n is the number of rows or number of columns of the matrix, whichever is smaller). In many use cases, the original matrix is sparse but the Gram matrix might not, and we often need only the largest k singular values/vectors. To make svd really scalable, the memory usage must be propositional to the nonzero entries in the matrix.
One solution is to call the de facto standard eigendecomposition package ARPACK. For an input matrix M, we compute a few eigenvalues and eigenvectors of M^t*M (or M*M^t if its size is smaller) using ARPACK, then use the eigenvalues/vectors to reconstruct singular values/vectors. ARPACK has a reverse communication interface. The user provides a function to multiply a square matrix to be decomposed with a dense vector provided by ARPACK, and return the resulting dense vector to ARPACK. Inside ARPACK it uses an Implicitly Restarted Lanczos Method for symmetric matrix. Outside what we need to provide are two matrixvector multiplications, first M*x then M^t*x. These multiplications can be done in Spark in a distributed manner.
The working memory used by ARPACK is O(n*k). When k (the number of desired singular values) is small, it can be easily fit into the memory of the master machine. The overall model is master machine runs ARPACK, and distribute matrixvector multiplication onto working executors in each iteration.
I made a PR to breeze with an ARPACKbacked svds interface (https://github.com/scalanlp/breeze/pull/240). The interface takes anything that can be multiplied by a DenseVector. On Spark/milib side, just need to implement the sparsematrixvector multiplication.
It might take some time to optimize and fully test this implementation, so set the workload estimate to 4 weeks.
