New Java Matrix Benchmark Results Coming

I'm in the process of executing the Java Matrix Benchmark on a Google Cloud Platform Compute Engine (n1-highmem-4 (4 vCPUs, 26 GB memory) with Intel Skylake processors). Actually I'm doing 3 separate benchmark executions using 3 different JVM:s on otherwise identical machines:

1. Java(TM) SE Runtime Environment (build 1.8.0_161-b12) 
2. Java(TM) SE Runtime Environment (build 9.0.4+11) 
3. Zing Runtime Environment for Java Applications (build 1.8.0-zing_18.04.0.0-b2) 

When all is done it'll be very interesting to compare the results between the JVM:s.

The results for all pure Java libraries running on Oracle 8 are already complete. Here's the summary performance chart for that:

It'll be another 2 weeks or so before everything is done. By then there will be results for these library and JVM combinations:

		Oracle 8	Oracle 9	Zing 8
Colt	1.2.0	X	X	X
Apache Commons Math	3.6.1	X	X	X
EJML	0.33	X	X	X
JAMA	1.0.3	X	X	X
jblas (using native code)	1.2.4		X
la4j	0.6.0	X	X	X
MTJ (pure Java)	1.0.7	X	X	X
MTJ-N (using native code)	1.0.7	X	X
ojAlgo	45.0.0	X	X	X
Parallel Colt	0.9.4	X	X	X
UJMP (pure Java)	0.3.0	X	X	X
UJMP-N (using native code)	0.3.0	X	X

The jblas library (using native code) crashed the benchmark twice running on different JVM:s. As part of the plan for how to recover and resume the executions it was decided to not re-run the libraries using native code on the all the instances – to save time. The native code libraries are not the most interesting when comparing JVM:s.

Further, and more detailed, results will be published here, at the ojAlgo wiki and/or at the Java Matrix Benchmark web site:
