Message 4649 - Posted: 7 Oct 2018, 8:47:01 UTC

Hello,
Considering the post of Admin,
The new WU (S370 and 716 need about 10 minuts to run (on a 3.8Ghz))
On my host 104672, I have WU already 3 hours running
After restart, again started from null because no checkpoint/.
It is not the problem, we know it.

The problem is that WU are stuck at 100% !!!
One of the WU after 15 minuts running is at 100% and the other started at the same time are at 20% !!!

Who can explain ???
Best regards

Can you check the stderr.txt file? You can calculate the runtime see FAQ. You can also post the content of the file here.

Hello,
I followed your calculation as describe in FAQ.
It not correspond at all with estimated running time !
host 104769 task S370_200-250k_WU_12161_0
(not yet returned) I guess about 15:15 UTC)

this happens from time to time.
for me i decided to look in the stderr-file and calculate the runtimes for myself

For this WU the runtime should be 65min. Maybe CPU is throttled.

Maybe CPU is throttled.


this is possible, when looking at the time per bit

my times right now:

Using all-complex FMA3 FFT length 144K, Pass1=768, Pass2=192, 6 threads, a = 3

159*754^133803+1, bit: 50000 / 1278944 [3.90%]. Time per bit: 0.351 ms.
159*754^133803+1, bit: 100000 / 1278944 [7.81%]. Time per bit: 0.292 ms.

Starting N-1 prime test of 106*716^216968+1
Using all-complex FMA3 FFT length 256K, Pass1=128, Pass2=2K, 5 threads, a = 3

106*716^216968+1, bit: 50000 / 2057682 [2.42%]. Time per bit: 0.499 ms.
106*716^216968+1, bit: 100000 / 2057682 [4.85%]. Time per bit: 0.488 ms.
