(I have > yet to test this, however, as I don't have GCC3.2 working on my alpha.) I'm not sure if the gap has become smaller, but ccc still generated code that is a lot faster than gcc-3.2. For example, take a look at these results from SCIbench (http://math.nist.gov/scimark2), generated on an quadruple-proc EV67 machine (running Tru64 Unix btw, not Linux): Compaq C compiler, V6.4-014 CFLAGS = -arch ev67 -fast -O4 | Composite Score: 195.47 | FFT Mflops: 207.66 (N=1024) | SOR Mflops: 235.00 (100 x 100) | MonteCarlo: Mflops: 53.33 | Sparse matmult Mflops: 177.93 (N=1000, nz=5000) | LU Mflops: 303.42 (M=100, N=100) GNU C compiler, V3.2.1 CFLAGS = -O3 -fomit-frame-pointer -ffast-math -mcpu=ev67 | Composite Score: 137.18 | FFT Mflops: 188.23 (N=1024) | SOR Mflops: 167.08 (100 x 100) | MonteCarlo: Mflops: 49.71 | Sparse matmult Mflops: 163.85 (N=1000, nz=5000) | LU Mflops: 117.03 (M=100, N=100) -- Kind regards, +--------------------------------------------------------------------+ | Bas Zoetekouw | GPG key: 0644fab7 | |----------------------------| Fingerprint: c1f5 f24c d514 3fec 8bf6 | | [EMAIL PROTECTED], [EMAIL PROTECTED] | a2b1 2bae e41f 0644 fab7 | +--------------------------------------------------------------------+
