In todays world of research computing, with its complex mathematical models,
there is an increasing need for low-cost, high-performance computing solutions.
Viglen’s HX series Servers, offer a range of 1U Dual-Core products providing
the best of both Intel and AMD technology in a variety of solutions, ranging
from single CPU right through to four processor Dual core systems.
Viglen’s compute clusters consist of a number of Intel or AMD processor based
1U nodes (rackmountable machines which consume 1 unit of a rack cabinet). These
nodes, by default, are all connected by Gigabit Ethernet. Optionally, should
your application demand a low latency, high bandwidth network interconnect,
we can offer Infiniband adapters and interconnects.
Viglen’s computer clusters employ a multi-tier architecture which is fully
scalable. The front tier consists of a master node(s) which connect to, both,
the external world and the rest of the cluster. This nodes acts as the cluster
coordinator and handles all user logins, job scheduling, nfs,
management/control of compute nodes.
The processing tier consists of high density (1U) compute nodes. Jobs launched
from the master node will be executed on these nodes. Typically these nodes
will be interconnected using Gigabit Ethernet, but high end interconnects can
also be used to separate the traffic on these nodes (Gigabit for NFS and a
fiber solution for low latency, high bandwidth MPI)
A Data Tier (optional) can be used in high end systems where large amounts of
storage are required or high volume parallel IO is necessary.
