I have ftp'd a new beta release of the mers package to:

I'm announcing it to the mailing list because it includes a brand new

Unless you're doing a timed run, maybe "kill -STOP pid" and "kill -START
pid" on the ecm3 run might give more accurate results - I hate to think

My early tests on a 200MHz UltraSparc are not that encouraging.
./MacLucasUNIX -C -S 10 141
speed: 10 iters in 1.668 seconds, 0.167 iters/sec (fft len 128k)
speed: 10 iters in 1.688 seconds, 0.169 iters/sec
When I leave my computer alone and let Prime95 run, it will
repeat the same second per iteration amount (.209 for M741)
for the most part. However, for about 2000 to 3000 iterations,
it will increase. Sometimes it only goes to .214 or .256, but
I've seen it as high as .544. What's going on?

It might be some scheduled service working.

I'm not surprised. The performance of FFTW seems is no so good in other
machines than x86, as E. Mayer commented in a recent m

Only runtime wisdom - Will didn't put tunefftw.c in the distribution.
If you or Will can send me a copy I'll try the tests again.

I recommend to use tunefftw when the system is bored, i. e. when no
other idle programs like mprime or ecm3 are runnig,

One more idea--virus scanners.

OK, I've ftp'd a new beta release that includes tunefftw.c and runs it
before doing the test of MacLucasFFTW.
I've kept a not-very-clos
