Looking good with two instances running.

kladner · 2011-12-20, 15:17

Running on GTX 460, at 875MHz.

Exponent a is 541216xx
Exponent b is 544325xx
71-72 bit.

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

When I ran it, I got this:

Code:

  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!

My command to start it is

Code:

LD_LIBRARY_PATH=./lib taskset -c 7 ./mfaktc-lin-64

with

as the setup. (Ownership is root because ~/mfaktc is a link to a folder on my Windows partition, so there aren't really 'ownerships' that I can change.)

Edit: Heh -- try numbers 2, 3, 4, 5, 6, 7, and 8:

Code:

CUDA driver version       797969.80

CUDA driver version       -62620.0
CUDA driver version       300866.32
CUDA driver version       2033957.60

With the negatives, the error changes to

Code:

ERROR: current CUDA driver version is lower than the CUDA toolkit version used during compile!

All runtime versions reported as 0.0.

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?

Dubslow · 2011-12-21, 04:11

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

Dubslow · 2011-12-21, 04:34

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.
