Dear users,
I am using ubuntu 11.1 (64 bit). The Ubuntu normally runs when I dont
run the Gromacs program. i.e there is not heating problem. But the CPU
is excessive heating (82 degree) when I run the gromacs.
There are various "stress test" programs you can get if you Google
around. I expect these will produce the same symptoms.
I am using the all cores at 100%. Now I have 2 PC.I use them separately
1.first: It has Intel i7 920 CPU and Asus P6T SE motherboard
2.second: It has Intel I7 960 and G?gabyte x58A-UD5 LGA 1366 motherboard
I have the problem of warming/overheating on both computers. I could
not figure out this problem for two weeks :(
By the way:
-I dont use an older compiler to get the binary. I am using gcc 4.6
and I am using Gromacs 4.5.4
-I watch the temperatures by "lm sensor" program
-I installed ubuntu 32-bit but the result didnt change again
-I have sufficient cooling on both PC
I'd say this is evidence that you don't have sufficient cooling.
It is likely something related to the program because no problem with
any hardware related to computers according to experts say.
If things are installed correctly. For example, cheap thermal paste
between the CPU and heat sink can cause these symptoms.
what do you suggest? :(
Get more cooling. Maybe lower the clock speed (if possible). Run a less
efficient MD code!
