Also versuche ich, den K80 unter Ubuntu 14.04 mit Cuda anstelle des OpenCL-Kaufs unter Verwendung von https://github.com/Genoil/cpp-ethereum Miner zum Laufen zu bringen. Ich habe die Anweisungen für Ubuntu 14.04 und Cuda befolgt und die Schritte mehrmals befolgt, kann Cuda jetzt jedoch nicht zum Laufen bringen. Hier ist ein Ausdruck von 'Nvidia-smi'

Ich habe gelesen, dass der k80 2 Prozessorsätze hat, es hat 24 GB RAM in 2 * 12 GB, Sie können nur den 1 des Prozessors oben sehen.
Ich habe cpp-ethereum heruntergeladen und der Readme-Datei gefolgt. Ich habe CMake noch nie zuvor verwendet, aber hier ist die Ausgabe

Was mache ich falsch?
Vielen Dank
Auch ich bin verwirrt durch diesen Schritt, "sudo apt-get https://github.com/Genoil/cpp-ethereum/blob/master/README.md -y install software-properties-common" apt-get dann a git Repository, was versucht man hier zu erreichen?
Dies wurde von jemandem verursacht, der versuchte, die Kompatibilität mit Fedora zum Laufen zu bringen. fügen --std=c++11Sie die NVCC-Flags in CMakelists.txt im Ordner libethash-cuda hinzu
Sie müssen also tatsächlich einige Änderungen an der geklonten Quelle vornehmen.
herunterladen:
git clone https://github.com/Genoil/cpp-ethereum.git
cd cpp-ethereum/libethash-cuda
vim CMakeLists.txt
Wechsel von
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};--disable-warnings;--ptxas-options=-v;-use_fast_math;-lineinfo)
Durch Hinzufügen von --std=c++11; :
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};--std=c++11;--disable-warnings;--ptxas-options=-v;-use_fast_math;-lineinfo)
