![]() ![]() NVML_GOM_LOW_DP Designed for running graphics applications that don’t require high bandwidth double precision. NVML_GOM_COMPUTE Designed for running only compute tasks. NVML_GOM_ALL_ON Everything is enabled and running at full speed. GOM allows to reduce power usage and optimize GPU throughput by disabling GPU features.Įach GOM is designed to meet specific user needs.

Oh, and is is possible to monitor clocks, but not set them. Here is the information on how to accomplish this: I just tested it on my Ubuntu install with 3.5.0-21-generic kernel and NVIDIA drivers 319.32 and nvidia-smi really does display the additional information with the shim! :)Īmong the additional things it lists for my GTX Titan that are otherwise N/A’d are: GPU Operation Mode Even if it doesn’t help in setting that flag, it is useful to monitor other GPU parameters via the command line. I’m posting the quote at the end of this post. Millecker sent me a PM lately regarding bypassing the NVML check of a supported GPU with regards to nvidia-smi. On the topic of being a headless node, to set that flag, you have at least 1 option, which is either faking a display – or, connecting an actual display, or heck, even a fake display –. = 177.055 double-precision GFLOP/s at 30 flops per interaction bandwidthTestĢ12992 bodies, total time for 10 iterations: 76867.023 ms ![]() usr/local/cuda/samples/bin/linux/release$. = 789.590 double-precision GFLOP/s at 30 flops per interaction GpuDeviceInit() CUDA Device : "GeForce GTX TITANĬompute 3.5 CUDA device: Ģ12992 bodies, total time for 10 iterations: 17236.391 ms ![]() nbody -benchmark -numbodies=212992 -device=0 -fp64ĭouble precision floating point simulation = 2008.821 single-precision GFLOP/s at 20 flops per interaction = 100.441 billion interactions per second nbody -benchmark -numbodies=229376 -device=0Ģ29376 bodies, total time for 10 iterations: 5238.231 ms = 172.414 double-precision GFLOP/s at 30 flops per interaction > Compute 3.5 CUDA device: Ģ29376 bodies, total time for 10 iterations: 91547.242 ms nbody -benchmark -numbodies=229376 -device=0 -fp64 Now, I am trying to repeat benchmark figures in the post To the compiler, and the warning disappeared. I’ve edited the Makefile to pass -gencode arch=compute_35,code=sm_35 -gencode arch=compute_35,code=sm_35 When I was compiling the NBODY tests, the compiler complained about double precision not being supported. I’ve installed the drivers 319.32 and I am using it with NVreg_EnablePCIeGen3=1, so that I see PCIe 3.0 speeds.
