Public bug reported: Ubuntu version: 16.04 Kernel: 4.4.0-67-generic
Issue: With current makefile setting "make -j$(nproc)". And on a 64 cores system the nvidia driver[1] installation stucks in "Building initial module for 4.4.0-67-generic" for about 20 mins. Workaround: repack driver to change setting to "make -j16" , then it just spend about 3 mins to pass "Building initial module" Investigation: from iotop, there are 35 processes were using >90% CPU, 23 processes >50% , it might could be a evidence that too heavy IO accessing by -j$(nproc) caused whole system hangs up when nv driver installation. htop: http://paste.ubuntu.com/24514786/ [1] https://launchpad.net/~graphics- drivers/+archive/ubuntu/ppa/+packages ** Affects: nvidia-graphics-drivers-375 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1688431 Title: driver installation cost about 20 mins on 64 cores system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-375/+bug/1688431/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
