This is a performance tuning option. EDA workloads tend to be highly concurrent. This setting dictates performance improvements for single-streamed workloads but may have a small performance penalty for some EDA workloads.
To check the current setting, run the following command:
isi_sysctl_cluster efs.bam.coalescer.multiwriter
Note: The default may be a different value based on the OneFS version.
The value of 1 is recommended in most EDA workloads. Specially on all-flash F series platform with latest OneFS version.
# isi_sysctl_cluster efs.bam.coalescer.multiwriter=1
