External Email - Use Caution Dear Freesurfer developers and users,
Has anyone had experience running Freesurfer on Linux VM on Google Cloud Platform? I have a question about runtime of recon-all -all. The specs of VM on GCP as follows, Linux CentOS 6, 16 CPU(Intel(R) Xeon(R) @ 2.50GHz) with 60 G memory I installed Freesurfer v 6.0.0 and run recon-all -all -parallel -openmp num No matter what number I put (6,8,12,16 after openmp), the recon-all runtime of a single subject ranges 6-7 hours. It's just disappointing to compare to my own desktop. My own Desktop is Mac Pro (3.7 GHz quad-core intel xeon E5, 16G memory). The recon-all runtime (Freesurfer version 5.3.0, no parallel) for a single subject is usually 7~8 hours. Is this a reasonable runtime given the setting of VM? Only 1-2 hour shorter than my Mac Pro?? Or is there any configuration of VM I should pay attention to set up? Thanks, Yi-Fang Chuang ᐧ ᐧ
