Dear experts,
Hi! I see the following on the site:
Error 0x0 and 0x1 From FaHWiki Jump to: navigation, search
The 0x0 and 0x1 errors are unknown errors - all errors that are known
will end with some other error code and message, but those errors that Pande
Group hasn't seen before or did not know about, will end with error 0x0 or 0x1.
Note: The WU data of an unknown error can not be trusted and by definition
you'll never get any credit for it. If the 0x0 and 0x1 error cause is
identified and classified as some sort of EUE then you'll start getting credit
for such WUs. One possible cause of errors 0x1 and 0x0 is a hardware failure
(which is why the software is unable to classify them). If a RAM failure is
detected by the OS or for some reason the program wishes to allocate more
memory and the OS refuses, the OS will terminate FAHcore_* and the client will
no longer be able to communicate with the FAHcore producing Client-core
communications error: ERROR 0x1
0x0 errors are Unix Specific and under Linux this error often can be related to
Glibc incompatibility.
Note: When using the Gromacs core on Linux, this error is also generated in
circumstances where the Windows core would produce a "Gromacs Cannot Continue
further" EUE. Unfortunately Pandegroup are currently unsure how WUs are
triggering this error. As a result a normal EUE is not triggered, and the whole
WU gets dumped and lost. Folding-community: Guha Jayachandran's comment in
"Core status 0?"
Under the Gromacs33 (A0) core, this error is returned because even though the
cause is known, it has not yet been categorised. The error creates an output in
the log similar to this:
Warning: 1-4 interaction between and at distance 0.000 which is larger than
the 1-4 table size 8.298 nm
One possible cause for error 0x0 is forgetting to redirect the standard
output. If you're running in the background without a command such as './fah5
-verbosity 9 >/dev/null 2>&1 &', the simulation will probably get past 100% and
then create an error.
These are ignored for the rest of the simulation
This usually means your system is exploding,
if not, you should increase table-extension in your mdp file
It should be noted that you yourself cannot increase the table-extension, it
is an integral part of the WU
Error 0x1 is not always an "unknown error" When a WU expires, you may receive
this error:
As I have the Lincs error.Is my problem related to this type? As I am using
Suse linux and I added directly the gromacs software to Installation packages.
