About
The Tightly-coupled Capability System (TCS) is a cluster of IBM Power 6 nodes intended for jobs that scale well to at least 32 processes and require high bandwidth and large memory. It was installed at SciNet in late 2008 and is operating in "friendly-user" mode during winter 2009
Node Names
- node tcs-f02n01 is node # 1 in frame/rack #2
- entire list of 104 nodes can be seen with llstatus
Node Specs
There are 102 compute nodes each with:
- 32 Power6 cores (4.7GHz); each core is 2-way multi-threaded using SMT (simultaneous multithreading)
- 128GB of RAM (except for tcs-f11n03 and n04 which have 256GB each)
- 4 InfiniBand (IB) interfaces which are used for data traffic
- 2 GigE interfaces are used for rsh access and GPFS token traffic
