Project 1487 > 100%

Postby Peter Potrowl » Thu Dec 27, 2007 12:51 pm

Hello !

I'm folding a p1487 and the computer completed more than 100% of the calculation :shock: :

Code: Select all
No option -tpi
(single precision)
starting mdrun 'p1487_DPPC_DOPC_CHOL'
2500000 steps,   5000.0 ps.

[11:45:06] (Starting from checkpoint)
[11:45:06] Protein: p1487_DPPC_DOPC_CHOL
[11:45:06] Writing local files
[11:45:06] Completed 2501868 out of 2500000 steps  (100%)
[11:45:07] Extra SSE boost OK.
[11:45:08] Warning:  long 1-4 interactions


Is that normal ? Will the calculation finish ?

It's a known bug in that version of GROMACS33.

Gen 0 starts at 0% and goes to 100%. Gen 1 starts at 100% and goes to 200%. Gen 2 starts at 200% and goes to 300%.

You can force a core update BEFORE the WU passes 100%, this bug has been fixed, but it doesn't update automatically.

Gen 0 starts at 0% and goes to 100%. Gen 1 starts at 100% and goes to 200%. Gen 2 starts at 200% and goes to 300%.

Well, here, it's Gen 14 and it started at 0%. It has run for 25 days to reach 100%.

I deleted FahCore_a0.exe. It was downloaded again and I received the lines :

Code: Select all
[13:44:13] Protein: p1487_DPPC_DOPC_CHOL
[13:44:13] Writing local files
[13:44:13] Completed 2516603 out of 2500000 steps  (100%)

[13:44:13] CoreStatus = 1 (1)
[13:44:13] Client-core communications error: ERROR 0x1
[13:44:13] Deleting current work unit & continuing...


Then, a new WU was downloaded and began to fold.

I'm afraid I will not get credit for this WU... :( :( :(

Running qfix is worth a try if there's a wuresults_0x.dat file in WORK.
