[gpfsug-discuss] DMAPI multi-thread safe

Hi Experts :)

Could you please tell me if the DMAPI implementation for GPFS is multi-thread safe? Are there any limitation towards using multiple threads within a single DM application process?
For example: DM events are processed by multiple threads, which call dm* functions for manipulating file attributes - will there be any problem when two threads try to access the same file at the same time?

Is the libdmapi thread safe?

Best regards,
Tomasz Wolski
