Dear Freesurfers!
I am a new user of freesurfer and I intend to install it on a HPC system. There are two different systems available (see end of message). Could you please give me a hint which one is best suited wrt hardware and software.
In order to use these systems one also has to state some estimations of the needed resources. In detail, I have to estimate:
* CPU time * maximal number of parallel used CPUs * size of used RAM * size of permanent HDD usage * size of temporary HDD usage
Could you share some experience how many resources are usually used for the segmentation (recon-all) of a single subject?
Thank you & best wishes from Dresden, Daniel
--- 1.SGI Altix 4700 (Mars)
* For highly parallel and memory-intensive applications * 2048 cores Intel Itanium II Montecito 1.6 GHz * 6,5 TB memory * One partition for interactive operation with 128 cores * 68 TB SAN disk storage * 1 PB SAN tape archive * SuSE Linux Enterprise Server 10, SGI ProPack 5, batch system LSF * 13,1 TFlop/s peak performance
2. Linux Networx Evolocity II PC-Farm (Deimos)
* For capacity computing * 2576 cores AMD Opteron 2,6 GHz * 5,4 TB memory * 724 nodes with 1, 2, or 4 dual-core CPUs each * 68 TB SAN disk storage * SuSE Linux Enterprise Server 10, batch system LSF * 13,9 TFlop/s peak performance
