Sage - Performance is off #56
Description
Hey there,
I have a system that is similar to the one described in the paper and was trying to compare some of the results on the WDC'12 graph but found really poor results. In particular, I found a ~15x difference for BFS (11 vs I50) in 1LM. I was wondering if it could be due to specific system settings (BIOS, etc.), myself not using the software correctly, or the input graph itself.
As an example of running Sage, I used:
NUM_THREADS=96 ./sage/benchmarks/BFS/SemiAsymmetric/BFS -src 551626522 -c -m -f1 /mnt/pmem0/csr-wdc12.bytepda -f2 /mnt/pmem1/csr-wdc12.bytepda
An important difference from the paper is that I'm using the directed form at the moment, but should the performance be that drastically worse? I also turned on THP, but it didn't seem to make much of a difference. Any and all help is much appreciated!
