+# only once and unlinked only at the very end, then put the unlink=1
+# in the last group. This is the method demonstrated here.
+#
+# Note that if you have a read-only group and if the files will be
+# newly created, then all of the data will read back as zero and the
+# read will be optimized, yielding performance that is different from

+# The pmemblk engine does IO to files in a DAX-mounted filesystem.
+# The filesystem should be created on an NVDIMM (e.g /dev/pmem0)
+# and then mounted with the '-o dax' option. Note that the engine
+# accesses the underlying NVDIMM directly, bypassing the kernel block
+# layer, so the usual filesystem/disk performance monitoring tools such
+# as iostat will not provide useful data.
+#
+# Here we specify a test file on each of two NVDIMMs. The first
+# number after the file name is the block size in bytes (4096 bytes
+# in this example). The second number is the size of the file to
+# create in MiB (1 GiB in this example); note that the actual usable
+# space available to fio will be less than this as libpmemblk requires
+# some space for metadata.
+#
+# Currently, the minimum block size is 512 bytes and the minimum file
+# size is about 17 MiB (these are libpmemblk requirements).
+#
+# While both files in this example have the same block size and file
+# size, this is not required.
