Linux Number Crunching: Languages and Tools

ChaoticCoyote writes " You've covered some of my past forays into benchmarking, so I thought Slashdot might be interested in Linux Number Crunching: Benchmarking Compilers and Languages for ia32. I wrote the article while trying to decide between competing technologies. No one benchmark (or set of benchmarks) provides an absolute answer -- but information helps make reasonable decisions. Among the topics covered: C++, Java, Fortran 95, gcc, gcj, Intel compilers, SMP, double-precision math, and hyperthreading."

Re:Java is slow?

gcj really is within 10% of g++ on this benchmark, unfortunately he built the gcj program without the all important -ffast-math option (and -funroll-loops). This is a huge penalty for gcj - more than 2x slower without.

I sent him a note and hopefully he's update his page.

Almost *ALL* of my email is related to Java. I'll be adding the IBM JDK and older versions of the Sun JDK later today, as per reader request.

I'm making minor updates to the article as the day passes. I appreciate comments from everyone; once I'm through with my e-mail, I'll respond to these Slashdot comments.

Additional benchmarks will be added to the article with time; I'm putting together a single-precision ("float") benchamrk, for example.
