Executive Summary

Evaluating Compiled Execution Efficiency

This interactive breakdown analyzes retired Microsoft systems engineer Dave Plummer’s single-threaded Sieve of Eratosthenes benchmark. The test evaluates how compiler optimization backends, memory abstraction layers, and instruction set primitives impact raw computational throughput across three foundational compiled languages.

Prime Limit ($N$) 1,000,000 78,498 Expected Primes

Test Window 5.0 Seconds Fixed Non-Extendable

Peak Throughput 13,500 P/s C++ Bitwise Engine

Performance Delta ~50x C++ / Fortran vs COBOL

Review findings for this part

The findings come from ../../findings/ (pass 1). The script matches them to this part by source line.

ID	Severity	Evidence	Status	Location	Problem
D10-C1	critical	VIDEO DOC	open	L84-86, L229, L353	Claim: “Peak Throughput 13,500 P/s”, C++ range 10,000 to 13,500. Problem: The video gives 1936 passes for the C++ program of Dave (14:03). Report 09 gives “about 10,000”. The value 13,500 is in neither source. The page invents its headline number.
D10-C2	critical	VIDEO	open	L89-91, L114, L267, L353	Claim: COBOL at 252 P/s, “~50x” slower, lags “by ~98%”. Problem: At 13:51, Fortran gets 1163 passes and COBOL gets 1118 passes. Dave says that they are about the same speed. The bar chart shows the opposite of the video result.
D10-M7	major	VIDEO VERIFY	verify	L80-81, L302	Claim: “Executes for exactly 5.0 non-extendable seconds”. Problem: The Primes CONTRIBUTING file says “at least 5 seconds”, then stop as soon as possible (checked by WebFetch). At 10:25, the Fortran program checks the time after each full pass.
D10-M8	major	DOC	open	L63-328	Claim: Footer: “Based on Dave’s Garage Episode 04”. Problem: The page has no citation and no link to the video. A reader cannot trace any number. Almost no content comes from the episode itself.
D10-m2	minor	DOC	open	L74, L140, L297, L302	Claim: “$N$”, “$N = 1,000,000$”, “$P/s$”. Problem: The page loads no math library. The reader sees raw dollar signs.
D10-m8	minor	VIDEO KNOW	open	L68, L76	Claim: Dave Plummer is a retired Microsoft engineer. N is 1,000,000 with 78,498 primes. Problem: These are correct. The video confirms Dave (00:58) and the one-million limit (13:03). 78,498 is the correct count of primes below one million.
