Those errors appear to pop up when qemu can’t find enough RAM to run. If the #SBATCH lines are only applicable for ‘sbatch' and not ‘srun' or ‘salloc', the ‘--mem=8G' setting there doesn’t affect anything.
- Does the srun version of the command work if you specify 'qemu-system-x86_64 -m 2048' or lower in the script? - Does the srun version of the command work if you specify '--mem=8G' along with the other parameters? - What’s the DefMemPerCPU setting you see from ‘scontrol show partition’ for whatever your default partition is (grep ‘default=yes’ /path/to/slurm.conf to find out what partition that is)? I suppose there’s a slim chance of srun adding an additional process to your resource reservation compared to salloc, but that’s just a guess. > On Jan 3, 2019, at 2:23 AM, Mahmood Naderan <mahmood...@gmail.com> wrote: > > Mark Hahn, > > Using srun only returns a memory allocation error while salloc doesn't > > [mahmood@rocks7 ~]$ srun --spankx11 ./run_qemu.sh > qemu-system-x86_64: -usbdevice tablet: '-usbdevice' is deprecated, please use > '-device usb-...' instead > qemu-system-x86_64: warning: host doesn't support requested feature: > CPUID.01H:ECX.fma [bit 12] > qemu-system-x86_64: warning: host doesn't support requested feature: > CPUID.01H:ECX.f16c [bit 29] > qemu-system-x86_64: warning: host doesn't support requested feature: > CPUID.80000001H:ECX.tbm [bit 21] > qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate > memory > srun: error: compute-0-2: task 0: Exited with exit code 1 > [mahmood@rocks7 ~]$ salloc --spankx11 ./run_qemu.sh > salloc: Granted job allocation 292 > qemu-system-x86_64: -usbdevice tablet: '-usbdevice' is deprecated, please use > '-device usb-...' instead > qemu-system-x86_64: warning: host doesn't support requested feature: > CPUID.01H:ECX.fma [bit 12] > qemu-system-x86_64: warning: host doesn't support requested feature: > CPUID.01H:ECX.f16c [bit 29] > qemu-system-x86_64: warning: host doesn't support requested feature: > CPUID.80000001H:ECX.tbm [bit 21] > salloc: Relinquishing job allocation 292 > [mahmood@rocks7 ~]$ cat run_qemu.sh > #!/bin/bash > #SBATCH --nodes=1 > #SBATCH --cores=1 > #SBATCH --mem=8G > #SBATCH --partition=QEMU > #SBATCH --account=q20_8 > USERN=`whoami` > qemu-system-x86_64 -m 4096 -cpu Opteron_G5 -smp cores=1 -hda > win7_x64_snap.img -boot c -usbdevice tablet -enable-kvm -device > e1000,netdev=host_files -netdev > user,net=10.0.2.0/24,id=host_files,restrict=off,smb=/home/$USERN,smbserver=10.0.2.4 > > > > > > Regards, > Mahmood > > > > > On Thu, Jan 3, 2019 at 6:21 AM Chris Samuel <ch...@csamuel.org> wrote: > On 30/12/18 9:41 am, Mahmood Naderan wrote: > > > So, isn't possible to override that "default"?
