Janardhan updated SYSTEMML-1140:
--------------------------------
Description:
We have identified two performance bugs that frequently occurs in deep learning
script.
First, we repeatedly perform unnecessary conversion to sparse format. Also, the
operations such as matrix multiplication (including BLAS and CuBLAS) are
optimized for dense.
Second, even with large memory budget, we sometimes spend almost 20-30% time in
caching.
[~mboehm7] [~reinwald] [~mwdus...@us.ibm.com] I am labeling this bug as blocker
for SystemML 1.0. Please feel free to assign this issue to yourself.
*Improvements so far:*
1. Disabled sparse conversions & caching, by
