Benchmark Update by P.D. Coker

Since carrying out the series of benchmarks which were published in Scorpio News Vi’Th (Jan-Mar. 1987), I have acquired one or two more compilers and Interpreters which T’ve cried out on a Genial Multiboard system fitted with the GHeGe processor, under CP/H-00 (2.2) and CP/M-86, as appropriate. For purposes fof comparison, i ran the same benchmark on an Amstrad PCLS12 using MSDOS and DOS Plus = the latter enables one to run CP/M-86 prog:

The results are quite interesting The benchmark used was obtained from Dr Dobbs Journal in which the iden was to produce a result ms near to 2500 a5 possible, using a range of intrinsic furctiont available in the interpreter oF Poaptler

‘The Following language implementations were availabl Nevada Fortran (2t0, cP/m 80) Utah Foreren sp0s) ProForeran (Cb/M-86 and DOS Plus) Biceosofe Fortran-77 (MSD0S) BaSrCus v. 5.28 «spos) Bastces v. 3.21, (Dos. Plus) Guaasic s00s)

The Fortran versions were all compiled and the BASIC# were all interpreted. The Amstrad usea the 8086 16 bit CPU with « system clock frequency of SHir while the M888 uses the 8088 6/16 bit CPU at Mie with I/O via the aMiE 80- Bus

The resulte were as follows:
