Hello , I am running NAS parallel benchmark's BTIO benchmark (NPB v 3.3) for class D and 1 process.
`make bt CLASS=D SUBTYPE=full NPROCS=1` I have provided gcc's `mcmodel=medium` flag alongwith -O3 during compilation. This is on an x86_64 machine. I have tested with openmpi 1.4.3, 1.7, but I get "Error setting file view" when I run the benchmark. It works fine for 4,16 processes. Can someone point out what is going wrong? Thanks in advance. ________________________________________________________________________ NAS Parallel Benchmarks 3.3 -- BT Benchmark No input file inputbt.data.
