Results from IBM Cobol compiler

[awierzch]

Based on https://github.com/PlummersSoftwareLLC/Primes/tree/drag-race/PrimeCOBOL/solution_1, I run this program on real mainframe. The results:

Passes: 02355, Time: 50, Avg: 000212 (sec/pass), Limit: 1000000, Count: 0078498,
 Valid: True
fvbakel_Cobol;02355;50;1;algorithm=base,faithful=no,bits=8

This is a link to a repo created by @andrew890, that includes the z/OS adaptations for COBOL, C++ and Java solutions from this repo: https://github.com/andrew890/Primes-zOS. I guess the COBOL adaptation is very similar to yours, but I am wondering if it would be possible to run the C++ and Java solutions on a mainframe as well, and post the results those generate?

I had been meaning to publish the results of my tests of C++ and Java on z/OS.

I have written up the results here:

The COBOL code is the same as contributed by awierzch. I just simplified the JCL to make it easy to run from the git checkout directory, and tidied up the output formatting a bit. The COBOL score is almost exactly the same.

That's a very nice post!
