SPDK backend #14

Closed neel-patel-1 closed 1 year ago

Hi. Very interesting work.

I am wondering how to use an NVMe-SSD based far memory as the backend as mentioned in Sec. 7: "We integrated two far memory backends into AIFM: a remote memory server based on a DPDK-based TCP stack, and an NVMe SSD using an SPDK-based storage stack." Also I am having trouble finding where the implementation for the alternative SSD-based back end is located. I am also curious if/how other far-memory backends could be integrated into AIFM. Any hints in this regard would be greatly appreciated.

Thank you so much

Hi neelpatelbiz,

Thanks for your interest. We initially support an SPDK-based backend based on shenango's storage stack, but later drop it as it's impossible to implement the "remote agent" atop the storage-based far memory. If you're interested to the code, I'm happy to add you into my development repo and point you to the related commit.

Thanks, Zain

I would be interested in seeing the storage-stack code. If you are able to add me to the repo, that would be great. Thanks

Just sent the invitation. 06ac2132167132f6f50de4ee4e3d810c7a834403 is the last commit that includes SSDDevice, which is located at apps/far_mem_storage/{inc/device.hpp, src/device.cpp}.
