You can also forward your ssh-agent through the ssh connections that you make so that you donโt need to copy your private key off of your laptop

Practically, Iโve used a shared IB network to pivot between systems that I did not have logical access to, but that did have a shared Lustre filesystem.
13.02.2025 13:04 โ ๐ 0 ๐ 0 ๐ฌ 0 ๐ 0Solid question. I consider IB to be a layer 2 network without many of the segmentation tools that IP routing gets you. Once you set up RDMA, you also lose most abilities to monitor and control traffic over that channel

11.02.2025 21:35 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 0Oh thatโs neat, I didnโt realize that. Iโm assuming that there is negligible hypervisor overhead?
11.02.2025 15:04 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 0Yeah. I hear that, especially for scientific codes. For things like drivers and system services I think memory safety is worth the hassle.
11.02.2025 13:10 โ ๐ 0 ๐ 0 ๐ฌ 0 ๐ 0They may be geeky, but theyโre a crucial if not very visible part to our day to day lives. Weather forecasting is a big one as well as industrial uses like development of complicated stuff like more cost efficient jet engines and new medicines.
