JURON und JURECA both share a common file system (*GPFS*). For working on both machines simultaneously, a dedicated folder for a build on each machine might be helpful.
JURECA offers `$HOME` and `$WORK` for long-term and short-term (but somewhat faster) storage of data. JURON offers both locations as well, but without any difference in connection speed.
## Useful GCC Compiler Options
*`-Ofast`: Compile with optimizations for speed
*`-flto`: Enable link-time optimization
*`-mcpu=power8`: Set architecture type, register usage, and instruction scheduling parameters for POWER8
*`-mveclibabi=mass`: Use the MASS vector library for vectorization
