How many cores/processors? In an earlier email you stated that you 
wanted to process many recons at the same time. If this is the case than 
the number of processors would be the limiting factor.

FYI: Freesurfer version 6 will include a "-parallel" flag which will use 
4 processors (by to default) to proces both the left and right 
hemispheres of the brain. This drastically reduces runtime and the 
expense of resources.

I'd add that that GPU should be very capable of running the
CUDA-accelerated applications as well. I'd be interested in seeing the
mri_ca_register times.

[Freesurfer] Fwd: hardware question

2016-01-28 Thread Joost Janssen 
Hi,

We're thinking of buying a computer with the main goal simultaneous
processing of 'recon-all's'. the computer cannot be a 'cluster' and must be
linux. These specs looked good to us:

- Intel Core i7-5820K 3.3Ghz

- Asus X99-A

- Arctic Cooling Freezer A30 CPU Cooler

- G.Skill Aegis DDR4 2400 PC4-19200 16GB CL15

- Samsung 850 Evo SSD Series 500GB SATA3

- Toshiba 4TB 7200rpm SATA3

- Aerocool Aero 800 Negra USB 3.0

- AeroCool KCAS 700W 80 Plus Bronze

- Asus GeForce Strix GTX 960 DirectCU II OC 4GB GDDR5

Are there things we can improve at? Thanks for any advice!

Hi Joost

how many cores does it have? And 16G of ram total, right?

Are you intending to run multiple recons at the same time or try to speed 
up single runs?

cheers
Bruce
