[parsec-users] Errors running Parsec benchmarks in M5

Hello,

Sorry for the confusion:
The difficulty with facesim is that I am running using M5, therefore in my
disk images need to supply a rcs file. It would of been easier and more
flexible if I can specify the input and output directory like the other
parsec benchmarks. But I can still manage.



As for swaptions there is an error, sorry for the lack of clarity:
There should be 16 swaptions but this is the exact output:

PARSEC Benchmark Suite Version 2.1
Number of Simulations: 5000,  Number of threads: 4 Number of swaptions: 16
Swaption0: [SwaptionPrice: 0.0000234735 StdError: 0.0000083599]
Swaption1: [SwaptionPrice: 0.0000234735 StdError: 0.0000083599]
Swaption2: [SwaptionPrice: 0.0000234735 StdError: 0.0000083599]
Swaption3: [SwaptionPrice: 0.0000234735 StdError: 0.0000083599]
Swaption4: [SwaptionPrice: 0.0000234735 StdError: 0.0000083599]
Swaption5: [SwaptionPrice: 0.0000234735 StdError: 0.0000083599]
Swaption6: [SwaptionPrice: 0.0000234735 StdError: 0.0000083599]
Swaption7: [SwaptionPrice: 0.0000234735 StdError: 0.0000083599]
Swa


Not sure whats going on here....The program exit while typing "Swa". Very
strange.


Thanks
