Subject: [SCore-users] new Cluster
Message-ID: <47DE4243.3010706@informatik.tu-cottbus.de>

Hi,

we are planning a new small cluster with 16 nodes with two 
quad-core-CPUs per node.

We tend to use Infiniband. Is this currently supported or what network 
you suggest to use?
Which controllers are working fine?

Currently Intel an AMD offers 4-Core-CPUs. Which CPU-type you suggest to 
use?

Sounds good.

Currently Ethernet and Myrinet (2)XP are supported in SCore 6 which  
is the current version. Infiniband, Myrinet10G as well as Ethernet  
will be supported in upcoming SCore 7 which is scheduled to be  
released in this year.

We usually recommend to use the Intel E1000 NIC for best performance.

We are aware of a performance problem with SCore 6 and earlier  
versions when the number of cores are 4 or above. This problem will  
also be fixed in SCore 7.
