DiskANN will assign an I/O context to each thread when doing io_setup(), MAX_EVENTS times the number of threads should not exceed the aio-max-nr in the system.
MAX_EVENTS is 1024 in DiskANN. The default aio-max-nr is 65536, so the maximum number of threads is 64.
To check the value of aio-max-nr on the system, run
