[MINOR] Performance createvar instruction, cleanup data handles

This patch improves the performance of string concatenation for
createvar instructions with unique filenames and removes the unnecessary
variable name from all data objects (matrices, frames, scalars).

[4/4] systemml git commit: [SYSTEMML-2009] Performance multi-threaded JMLC scoring (contention)

2017-11-09 Thread mboehm7

[SYSTEMML-2009] Performance multi-threaded JMLC scoring (contention)

This patch makes a major performance improvement to multi-threaded JMLC
scoring and script execution. For scripts with many small intermediates,
concurrent JMLC prepared scripts were contended on sequence ID
generators for unique matrix IDs, which is unnecessary because these IDs
are only used in the bufferpool which is disabled through JMLC. On an
end-to-end application with above characteristics, this changed improved
performance from 487s to 94s (in a test environment w/ 24 vcores).

[SYSTEMML-1990] Generalized ctable rewrites (seq-table, const inputs)

This patch generalized the existing rewrite for table(seq(),X,...) to
rexpand(X,...) to handle cases with unknown dimensions, including common
scenarios with column indexing on X. Additionally, this patch also
introduces a new rewrite for table with constant matrix inputs (i.e.,
table(X, matrix(7)) -> table(X,7)).
