The Dhrystone programs are by Reinhold Weicker. His email address is: Reinhold.Weicker@stm.mchp.sni.de
The Dhrystone C Programs (dhry.tar.Z.uue, or dhry.shar), and latest table of results (dhry.tbl) are available via anonymous ftp from 'marlin.nosc.mil' in directory 'pub/aburto'. The 'marlin' host number is: 128.49.4.4 . Please send new results (systems, machines, compilers, compiler options) to 'aburto@marlin.nosc.mil'. I will keep results updated, post to 'comp.benchmarks' periodically, and send results to Reinhold Weicker. Please read the 'README.1ST' file first for information regarding running the programs and submitting results. If you need the individual files please send email to aburto@marlin.nosc.mil .
The VAX 11/780 MIPS reference is 1757 V1.1 Dhrystones/second. The VAX 11/780 MIPS reference is 1757 V2.1 Dhrystones/second.
I used the same VAX 11/780 MIPS reference (1757) for both V1.1 and V2.1 since the results for unoptimized code in general were very similar, if not identical, in this case.
Reinhold Weicker recommended that both V1.1 and V2.1 MIPS results be collected as this would give a reference on how much more V1.1 can be optimized relative to V2.1. When quoting Dhrystone VAX MIPS ratings it is preferrable to use the V2.1 numbers. Reinhold Weicker has asked me to add the following statement: "Dhrystone author says: Relying on MIPS V1.1 numbers can be hazardous to your professional health" ...
Some compiler results which appear 'too high' compared to other compiler results on the same machine are indicated by an '*' --- just my way of keeping track of exceptional results from certain compilers.
Results as of 06 Sep 1993.
