They seem to use approx 600MB

They seem to use approx 600MB when running.

i7-6700 running 8 at a time takes approx 34,100 sec

i7-8700 running 12 at a time takes approx 39,500 sec

i7-8700 running 6 at a time takes approx 23,000 sec, but other cores were idle when I tested.

Haven’t tried them on Ryzen 7 yet. I presume app is avx (if cpu supports it). Are there any plans for an avx2 version? AMD and Intel work on different sizes which would further complicate things.

I see there is a v0.03 now up

I see there is a v0.03 now up from 0.02.

My hosts ask 200MB for Linux v0.01 and v0.03 (LIBC215) . 320MB for Win v0.02 and v0.03. I'v got a few generations older hardware than you... maybe that makes it.

First batch on Ryzen 7 1700 came in around 56,000 sec running 16 at once.

I think it will vary based on frequency. I am seeing current ones using around 200MB like you now. Previous ones were up to 600MB. Also app version has changed and it may use less than before.

I ran seven on my Ryzen 1700 (all cores loaded, not overclocked), and they came in at around 43,000 sec.  But then I remembered that it depends on frequency, and at 201.20 Hz, they are on the short side.  I guess the Ryzen works as well as my Haswell i7-4770, but it is hard to get a direct comparison.

I think you are right. I have some 459.60Hz using 320MB and talking about 46K sec

I have some 281.00Hz using 207MB. Waiting for them to finish but looks like they should be 4 hours faster. (28.8K Sec)

I ran another batch but only 8 at a time and they seem to be around 25,500 sec. I think work unit frequency was 199.65Hz. The other cores were idle for this test. It would appear the Hyper threading is not as good as intel.

None of my machines are overclocked, just stock CPU speed and the fastest memory the CPU supports without overclocking.

Looks like versions have reverted now back to 0.02  / 0.01 .

Just completed my first one

Just completed my first one on my Ryzen. Assume it ran on a HT core since I have the Seti CPU tasks locked to physical cores with affinity.  Used 327 MB of memory and run_time was 40,882 seconds and cpu_time was 40,820 seconds.  The type was 442.30Hz. Task 729505621
