These extra speedups are going to save me *days* of computing time in the long run. For my real-word apps I'm seeing a 1.3x speedup with MPIR 0.9 on 64bit AMD vs GMP 4.2.4 and between 1.2x and 1.7x speedup on 64bit Core2. The squaring code with 105000 digit integers: AMD Opteron 248 @ 2.2GHz (Linux 64bit) MPIR 0.9 = 83m11.177s GMP 4.2.4 = 108m41.370s Intel Xeon E5405 @ 2.00GHz (Linux 64bit) MPIR 0.9 = 121m20.354s GMP 4.2.4 = 208m40.348s Using GMP-ECM to ECM a 244 digit number with B1=11e6: AMD Opteron 248 @ 2.2GHz (Linux 64bit) MPIR 0.9 = 2m32.406s GMP 4.2.4 = 3m20.908s Intel Xeon E5405 @ 2.00GHz (Linux 64bit) MPIR 0.9 = 3m45.447s GMP 4.2.4 = 4m40.356s So thanks for all your hard work! With all the Core2 Windows stuff happening after 0.9.0 I will probably wait until 1.0 to test out my Windows binaries.
