Who wants to benchmark this on his/her BeagleBoard?

[Tom Turbo]

Hi everybody!
This is for everybody who has a BeagleBoard (any version) and is
willing to run a small benchmark for me.
It is phrot,a program for performing primality tests on big numbers
and relies heavily on double-precision floating point performance.
To run it.
First,download and extract the archive at the link below somewhere
onto your beagle.
Then,run ./makeit.sh
If it should fail with an error,please report!
If it succeded,you should have an executable called "phrot" in the
folder where you unzipped the archive.
If that's the case,run this:
./phrot -q 10^16384+1
Wait till it finishes and report all of the output here. Thanks!

Double-precision float on the Cortex-A8 is slow.

OK,that is something good to know.
Still interested how it compares to a 1.4 GHZ athlon xp with this
benchmark.

[Everett Wang]

Please publish the result to this group. I want to know the comparison. I have a
beagleboard C4 and am willing to help to run the benchmark. Please send the
benchmark software and instruction of how to run it.

Best regards,

Everett

The athlon will be at least 5x faster.

How much faster do you think a 1 GHZ Cortex A9(one core) would be in
this regard?

The A9 should be comparable to the Athlon.
