Hi, I have a couple of SCSI disks and Adaptec SCSI controller. I tried to access data blocks from the raw device in parallel using multiple threads and processes. I did succeed to some extent. So I was convinced that the tagged I/O works. Now, is there any way I can access the data blocks in parallel in a single thread/process? I am looking for a way to issue read requests in asynchronous/non-blocked fashion. Does aio_read(), aio_write(), etc. calls work? Is there any other way to do this? Any help is appreciated.
