Overview of the Tera MTA I
Tera computer system is a shared memory multiprocessor.
- From its specification, it also implements the true shared memory programming model for which the performance of the system does not depend on the placement of data in memory.
- i.e. a true uniform memory system (UMA) whereas Sun E10000 is almost UMA and Origin 2000 NUMA
The Tera is a multi-processor which potentially can accommodate up to 256 processors.
- The system runs stand-alone and requires no front end.
- Network connection to workstations and other computer systems is accomplished via 32- or 64-bit HIPPI channels.
- All data path widths are 64 bits, including the processor-network interface.
The clock speed is nominally 333 Mhz, giving each processor a data path bandwidth of one billion 64-bit results per second and a peak performance of one gigaflops.
