Running on GTX 460, at 875MHz.

Exponent a is 541216xx
Exponent b is 544325xx

Whoops, my bad. However, it said *.so.4.0.17, not 4.1.*.

When I ran it, I got this: [code]CUDA version info
binary compiled for CUDA 4.0
CUDA runtime version 0.0
CUDA driver version 297000.8
ERROR: CUDA runtime version must match the CUDA toolkit version used during compile!
[/code]
My command to start it is [code]LD_LIBRARY_PATH=./lib taskset -c 7 ./mfaktc-lin-64[/code] with [code]bill@Gravemind:~/mfaktc∰∂ ls -lR

I got this error running the linux64bit version:

:~/mfaktc-0.18$ ./mfaktc.exe -h
./mfaktc.exe: error while loading shared libraries: libcudart.so.4: cannot open shared object file: No such file or directory

mfaktc-0.16 works without errors.
Any Ideas?

do 'echo $LD_LIBRARY_PATH' and 'ls -l mfaktc-0.18' or equivalent.
Did you need anything special like a lib folder for mfaktc16?

echo $LD_LIBRARY_PATH
:/usr/local/cuda/lib64

lib folder is existing

ls -l /usr/local/cuda/lib64
ls -l mfaktc-0.18/lib

I'll check back every few minutes.

okay first try 'cp mfaktc-0.18/lib/* /usr/local/cuda/lib64' and try running again.
