Good morning Clinton,
On the following machine
Times reported below reflect averages over three executions.
Expect 20 minutes for suite to run to completion.
Word Size Main Memory C Compiler clock OS
32 bit 972 MB gcc 4.4.7 1.0 GHz UNIX
CPU
4x Intel(R) Atom(TM) CPU N570 @ 1.66GHz
Elapsed time h:m:s |Concurrent |
benchmark |Sequential| |Concurrent|
|Performance|
concord concord.dat 13.453 N/A
deal 50000 11.879 N/A
ipxref ipxref.dat 7.263 N/A
queens 12 15.564 N/A
rsg rsg.dat 12.733 N/A
binary-trees 14 19.274
the current runtimes are about 10 slower than the example given.
Mind you, the bench marks are stalling on
binary-trees 14
at the moment.
Both runs have stalled at
binary-trees 14 19.274
I'll keep it running while outside and have a look later at where the
problem seems to be.
regards
Bruce Rennie
