----------------------------------------
Summary: Parfor w/ reused data partitioning causes diverging
results
Key: SYSTEMML-2293
URL: https://issues.apache.org/jira/browse/SYSTEMML-2293
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
For a special case of the following parfor structure, we see diverging results
with and without parfor data partitioning which are reused across the while
loop iterations.
{code}
while(...) {
parfor(...) {
Xi = X[i,] #reused row-wise partitioning
}
parfor(...) {
Xj = X[,j] #reused col-wise partitioning
}
}
{code}
