Yo,

it's just this branch:

https://github.com/memcached/memcached/pull/342

pass "-e /path/to/dax/mount/memcache" and it'll use the persistent memory
mount. The graceful restart code isn't complete yet, but you can ignore it
if all you want to do is test using persistent memory for capacity
reasons.

Should be in the mainline soon. I'm pushing to get it complete.

Re: persistent memory blog

2019-09-03 Thread Pradeep Fernando
Hi Dormando,

Thanks for the post!. I want to run the same benchmark/configuration for 
one of my workloads.
In the post, you mentioned,

"Persistent memory is enabled using a DAX filesystem 
 and a 
prototype patch for memcached’s restartable mode 
. The persistent memory is 
accessed via a mmap’ed file."

I have a pmem DAX file system and your mmap memory allocation patch would 
help me. Can you please share it -- I could not find a link in your post.
Further, I do not understand the additional requirement of 'memcached 
restartable mode' and how it relates to persistent memory.

Thanks in advance,
--Pradeep
