<div dir="ltr">Hi,<br>I'm very surprise to see the differences between these two same benchmarks on <a href="http://shootout.alioth.debian.org">shootout.alioth.debian.org</a> :<br>1) Quad core : <a href="http://shootout.alioth.debian.org/u64q/benchmark.php?test=chameneosredux&lang=hipe">http://shootout.alioth.debian.org/u64q/benchmark.php?test=chameneosredux&lang=hipe</a><br>
2) Mono core : <a href="http://shootout.alioth.debian.org/u64/benchmark.php?test=chameneosredux&lang=hipe">http://shootout.alioth.debian.org/u64/benchmark.php?test=chameneosredux&lang=hipe</a><br><br>Here are the CPU times :<br>
1) 2095.18 s<br>2) 37.03 s<br><br>I try on my machine[1] with a) "-smp enable" and b) "-smp disable" :<br>a) 47.863 s<br>b) 18.285<br><br>Maybe It's not strange to see a such difference because of inter-cpu message passing. But the difference on <a href="http://shootout.alioth.debian.org">shootout.alioth.debian.org</a> is too large<br>
What should we do ?<br><br>/Greg<br><br>[1] : (Dual-Core AMD Opteron(tm) Processor 2212 HE, 2GHz)<br></div>
