code runs slower in Mac!!!

Post by thats_karlo »

Hi,
I have installed Neruon on Mac. some code has tested and it works fine.

"test" .... i mean, create a model, insert current calmp and see firing pattern.

when i use a vlotage clamp, at first run (jump from a holding potential to a control) program is raunnig fast. but when we are at 5th level of control voltage, running is getting slower.

Do you think, is there some thing wrong in installation procces, or in code?

in run this code, in winxp, it works faster. but my Mac computer is more powerful. (
Processor Name: Intel Core Duo
- Processor Speed: 1.66 GHz
- Number Of Processors: 1
- Total Number Of Cores: 2
- L2 Cache (per processor): 2 MB
- Memory: 1 GB
- Bus Speed: 667 MHz
)



do you have any idea?

thanks
Karlo

A program that is written to run on a single processor machine does not
automatically execute faster when it is run on a multiple processor machine.
You have to write your model code in such a way that the model will be
distributed over multiple processors. You must also have other software
installed that sets up and manages communication between the processors.
In the case of NEURON, that software is called MPICH2. I don't know if it
is available for OS X.
