Hello, I just installed ArBB 1.0.0.008 on my system (OS=fc12.x86_64, CPU = 2 Quad-Core 2.8 GHz Xeon). As a test of installation quality, I executed the run scripts for the samples (build_run-icc.sh and build_run-gcc.sh). For some tests I observed significant C-to-ArBB speedups (such as a 89.1x speedup on ArBB1 for the monte-carlo test [O3, icc, non-debug]). However, for other tests I saw nominal speed-ups (such as back_projection) or even slow-downs (such as a 0.016x performance factor on ArBB3 for raytracing2 [O3, icc, non-debug].)
I was curious if this is the expected performance or is there something probably wrong with my installation? If you have a link to expected performance results for different platforms, that would be particularly useful for me to compare to.
