--------------------------------------
Assignee: Nakul Jindal
> Exception thrown when a GPU sparse-sparse matrix multiply is performed
> ----------------------------------------------------------------------

> Key: SYSTEMML-1138
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1138
> Project: SystemML
> Issue Type: Bug
> Reporter: Nakul Jindal

> For a simple program like so:
> A = rand(rows=50000, cols=100000, sparsity=0.0003)
> B = rand(rows=100000, cols=100, sparsity=0.7)
> C = A %*% B
> print(toString(C))
> This is the exception:
> Caused by: jcuda.CudaException: cudaErrorIllegalAddress
> at jcuda.runtime.JCuda.checkResult(JCuda.java:460)
> at jcuda.runtime.JCuda.cudaDeviceSynchronize(JCuda.java:7361)
