Dirk, thanks for trying it. It looks like (from the attached text you sent me), that unfortunately it ran the test on a single core
Code:
./fds5_mpi_linux_64 scale1.fds
Process 0 of 0 is running on ASUS-F1A75
Mesh 1 is assigned to Process 0
Mesh 2 is assigned to Process 0
Mesh 3 is assigned to Process 0
Mesh 4 is assigned to Process 0
Mesh 5 is assigned to Process 0
Mesh 6 is assigned to Process 0
Mesh 7 is assigned to Process 0
Mesh 8 is assigned to Process 0
I would have expected that to say something like Process 0, Process 1 or Process 2 for three threads.
I'm afraid running under Linux isn't something I've really tried. It's something I'm aiming for but I currently don't have a machine I can test it all on. I briefly tried using a live USB late last year but it didn't give particularly good benchmarks. I'm hoping to get a server machine cheap on eBay I can play with at home.
I mean my best bet would be to use the Amazon EC2 instances as that would save me money in comparison to buying something - however, they can't guarantee that I'll get the same CPU each time so it makes benchmarking a bit hard!
