I�m putting together a list of APSE evaluation tools/benchmarks/services that might be available to UK users. So far I�ve got: TOOLS/BENCHMARKS ACES PIWG suite (including Whetstones and Dhrystones) Hartstones SERVICES Ada Program Generator (from the UK National Physical Laboratory) GROW APSE stress tester (from the UK Defence Research Agency) Can anyone out there add to my list? By the way, did anyone ever implement the PN, AH, SH and SA series from the Hartstone reqts? David Cross
