2.2. Rust on Metis

Rust is a highly unique language that has C-level performance without C-esque memory issues.

No segfaults, no race conditions, no risk of another Therac-25.

Rust has multiple features positioning it as an ideal language for HPC:

• Rich ecosystem: Libaries for CUDA, parallelism, and distributed computing
• Memory safety: No leaking memory, no unexpected crashes at the end of your workload
• Blistering performance: With compiler optimizations, Rust can outperform C
• Revealing type system: Understand your data and its output before and after it's processed
