Availability of processors supporting Intel SGX

[liangcheng yu]

Hi Cloudlab Team,

I noticed there were similar questions in the prior post but no follow up information there.

I am wondering if there were any machines in Cloudlab supporting SGX and have it enabled?

A quick scan of the processors profiles in http://docs.cloudlab.us/cloudlab-manual.html seem to indicate there were no processors in the listed processors supporting SGX: https://www.intel.com/content/www/us/en/architecture-and-technology/software-guard-extensions-processors.html , but I just want to make sure.

Thanks!

Regards,

You can follow the processors links on:

https://www.cloudlab.us/portal-hardware.php

to be sure, but I believe only the Clemson "r650" and Wisconsin
"sm110p" and "sm220u" nodes support SGX.

Hi! I was validating the SGX support on an sm110p machine with Intel Xeon Silver 4314 Processor supporting SGX.

The terminal prints certifies the fact, yet it also indicates that the corresponding BIOS option is not enabled.

Does cloudlab supports on-demand BIOS config for SGX for machines like sm110p or sm220u? Thanks!
