3.4 Processor architecture
The microprocessor in each of the T3E nodes is a DEC Alpha 21164,
a RISC processor manufactured by COMPAQ/Digital. This 64-bit pro-
cessor is cache-based, superscalar, and has pipelined functional units.
It supports the IEEE standard for 32-bit and 64-bit floating point arith-
metics.
The range of a 64-bit floating point number is
2.2250738585072014 · 10
−308
...1.7976931348623157 · 10
+308
.
The mantissa contains 53 bits, and therefore the precision is about 16
decimal numbers.
Correspondingly, 32-bit floating point numbers are between
1.17549435 · 10
−38
...3.40282347 · 10
+38
The mantissa contains 24 bits (the leading bit is not stored), and the
precision is about 7 decimal numbers.
Specific characteristics of the processor are presented in Table 3.1.The
structure of the processor is illustrated in Figure 3.2.
