All Following the release of z390 v1.4.01a with new date and time callable routine named DAT that can be used for benchmark testing, I’ve published a first solution to problem #18. The solution shows that the MIP rate dropped 15% when using the new z10 compare and branch code, but the elapsed time in nano-seconds also reduced by 8%. Visit the web site to see source code including copy of the new DAT routine and the execution log showing results:
http://z390.sourceforge.net/z390_Mainframe_Assemble_Coding_Contest.htm I’ve also posted a new problem #19 to write code to find the last non-blank character in an 80 byte text line using the least number of instructions. Hint there is a z10 instruction that might be the fastest, but I could also be wrong. Enjoy the weekend!
