09:45:49 izza_ hi..can anyone help me here about error that we've encountered upon testing vgpu in devstack using tensorflow
09:46:16 izza_ encountering below error: The TensorFlow library was compiled to use SSE4.1 instructions, but these aren't available on your machine.
10:05:13 bauzas izza_: good morning
10:05:34 bauzas izza_: when you say "testing vgpus", you mean using https://docs.openstack.org/nova/latest/admin/virtual-gpu.html ?
10:06:05 bauzas izza_: I guess you use the libvirt driver with KVM ?
10:08:03 izza_ able to detect the vgpu...the thing is when we tried to deploy tensorflow in devstack, we're encountering such error.. yes, it is already set as KVM
10:08:26 bauzas izza_: I guess you probably don't have the right CPU model
10:11:02 bauzas izza_: which CPU mode do you use for all your computes ?
10:12:04 bauzas context is https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.cpu_mode
10:13:00 bauzas AFAIR, using "None" for your CPU mode in Nova makes you get a very old CPU model
10:13:08 bauzas for migration reasons
10:23:04 bauzas izza_: if you wanna get more on CPU models, see https://www.berrange.com/posts/2018/06/29/cpu-model-configuration-for-qemu-kvm-on-x86-hosts/
10:32:31 openstackgerrit Balazs Gibizer proposed openstack/nova master: DNM: troubleshoot cells v1 tests on gate https://review.openstack.org/621538
10:38:23 sean-k-mooney bauzas: using none for cpu mode should result in host model which will be the most recent cpu model that matches your host
10:40:30 izza_ so it should be none?
10:41:34 sean-k-mooney izza_: you should always set it explctly to a supported value or not at all.
10:41:51 sean-k-mooney none will indrectly result in host-model
10:43:44 sean-k-mooney oh actully maybe bauzas is correct https://github.com/openstack/nova/blob/master/nova/conf/libvirt.py#L490-L493
10:46:15 sean-k-mooney it looks like we treat the string "none" differently form that value None
10:46:18 sean-k-mooney https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L3796-L3815
10:47:48 openstackgerrit Lee Yarwood proposed openstack/nova master: WIP libvirt: Add workaround to remove instance dir during cleanup with rbd https://review.openstack.org/618478
10:48:07 sean-k-mooney izza_: try setting it to host-model explcitly
10:49:05 sean-k-mooney izza_: bauzas may already have covered this but you might also need to use a different vGPU type to enable tensorflow to work with gpu accleration.
10:49:17 sean-k-mooney only some models support opencl/cuda
10:50:48 bauzas sean-k-mooney: izza_: the conf option help says that cpu_mode defaults to host-model if KVM
10:51:07 bauzas so you should get the SSE4 instructions if your CPU is recent
10:51:25 bauzas but worth checking the guest XML
10:51:49 izza_ im checking it now
10:52:23 bauzas izza_: please tell us the config options values for [libvirt]/cpu_mode and [libvirt]/cpu_model
10:52:32 bauzas izza_: besides the virt type
10:52:36 sean-k-mooney sse4 is pretty old. i would be surprised if the host did not supported it
10:52:41 bauzas I agree
10:53:06 bauzas the only thing I could think of would be cpu_mode explicitely set to None
10:53:48 izza_ [libvirt]
10:53:50 bauzas which would make the guest using a very old CPU model that doesn't support SSE1
10:53:53 bauzas SSE4*
10:54:04 izza_ live_migration_uri = qemu+ssh://stack@%s/system
10:54:10 izza_ cpu_mode = host-passthrough
10:54:16 izza_ cpu_model_extra_flags = sse4_1
10:54:22 izza_ virt_type = kvm
10:54:47 sean-k-mooney izza_: host-passthrough will give you the same feature flags as the host. you dod not need the extra flags
10:55:14 izza_ noted on this..we will remove it..
10:55:23 sean-k-mooney izza_: you have sse in the hosts /proc/cpuinfo right?
10:55:39 izza_ but we tried to remove it and set is as passthrough without flags
10:55:48 izza_ but still unable to get the other flags
10:56:07 sean-k-mooney every xeon since nehelem has had sse 4.2+
10:56:26 izza_ yes, sse4.1 is available in /proc/cpuinfo
