Is Tesla K40C a Cuda-enabled GPU card ?

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

Is Tesla K40C a Cuda-enabled GPU card ?

Postby Graphic_design » Wed Sep 07, 2016 12:40 am

I have installed centOS 6.5 and window 8.1 OS on my Machine (GPU Superserver 7048 GR-TR with NVIDIA TESLA K40C). I have successfully compiled a test program hello.cu by using following commands
#nvcc –arch sm_20 hello.cu –o hello
I couldn’t execute it.
I have entered the following commands to verify whether GPU is CUDA capable or not:
# which nvcc
/usr/local/cuda-6.5/bin/nvcc

# ls –l /dev/nv*
Crw-r------1 root Kmem 10, 144 sep 1 09:14 /dev/nvram

# lspci|grep –I nvidia
02:00.0 3D controller:NVIDIA Corporation GK110BGL [Tesla K40c] (rev al)

# gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-17)

I also tried to find GPU in the machine by shifting from centOS6.5 to Window 8.1 operating system
After click on NVIDIA control panel in the pop-up window; I saw following message
NVIDIA display setting are not available You are not currently using a display attached into an NVIDIA GPU.

Hello Graphic_design, welcome to the Folding Support Forum.

Is the Tesla K40C a Cuda-enabled GPU card?
Answer: Yes. But Folding doesn't use CUDA any more. It uses OpenCL.

Try these:

I'm having trouble finding the exact device you're talking about.

Apparently it uses the GK110, which is supported.

I'm surprised that lspci didn't give you the binary codes describing the GPU. the following are similar to what you're describing and are supported, but I don't see an exact match. Please provide us with the full text of that line from lspci.

Code: Select all
0x10de:0x101e:2:3:GK110 [Tesla K20X]
0x10de:0x101f:2:3:GK110 [Tesla K20]
0x10de:0x1020:2:3:GK110 [Tesla K20x]
0x10de:0x1021:2:3:GK110 [Tesla K20Xm]
0x10de:0x1022:2:3:GK110 [Tesla K20C]
0x10de:0x1023:2:3:GK110 [Tesla K40m]
0x10de:0x1024:2:3:GK110 [Tesla K40c]
0x10de:0x1026:2:3:GK110 [Tesla K20s]
0x10de:0x1027:2:3:GK110 [Tesla K40st]
0x10de:0x1028:2:3:GK110 [Tesla K20M]
0x10de:0x1029:2:3:GK110 [Tesla K40s]
0x10de:0x102a:2:3:GK110 [Tesla K40t]
0x10de:0x102d:2:3:GK110 [Tesla K80]
0x10de:0x102e:2:3:GK110 [Tesla K40d]


FAH uses mostly single precision but I don't know if the compiler produces (MAD+MUL) or (MAD or FMA) for those operations.

Re: Is Tesla K40C a Cuda-enabled GPU card ?

Postby bruce » Fri Sep 09, 2016 12:23 am

It looks like you have a 0x10de:0x1024:2:3:GK110 [Tesla K40c] but RH doesn't give you the binary codes.

Yes, it's enabled for CUDA and may or may not be enabled for OpenCL depending on where you obtained the drivers and/or which options you chose.
