I had to compile it from source as I was running into the same issue. On Ubuntu 14.04, I installed nvidia-cuda-toolkit, changed the cuda install location at the top of Makefile to /usr, ran `make`, and it worked.

To everyone else: I still don't have any benchmarks for Compute 5.0, 3.5 or 2.1 under CuLu 2.05, so more benchmarks are welcome, either here or james@mersenne.ca

Here are two benchmarks for low end 2.1 cards. Attached are the command outputs.

Thanks. Those numbers are a fair bit higher (~25%) than expected. If someone has a higher-end Compute 2.1 card (e.g. GTX 460 or 560) that matches those numbers I'll feel more confident in updating the chart.

They were done with CUDA 5.5 if it matters.

Your 560ti result was more in line with what I'd seen before. These numbers are from v2.05 correct?

I already have 570/580 results, but more is merrier if you have them handy. I would also be very interested in your 780/Titan/Black results please.

Mark Rose · 2015-02-28, 01:54

I can bench on three more 580's and a 760 if it would be useful.

Your Titan/Titan Black are about 1-2% faster than mine

.
Were they done with P95 running? (mine yes, I try to go for "as close to real conditions as possible" when I build them)
Or you keep them cooler? (how? mine are air cooled and with hot Thai days they lose a lot of productivity when the aircond is off, for example, the TDP go down, and the iterations go from 3 to 4 ms, or even 5 etc.)
Just curious.
