T3E systems contain a large number of processing elements PE. Broad range implementation Cray T3E system has their own local memory. All address are represented using bytes. Two consecutive bytes form a word, four bytes form a longword, eight bytes form a quadword. Register: The Alpha architecture includes 32 general-purpose register from R0 to R R31 always contain the value zero.
Each general-purpose register in Alpha architecture of Cray T3E system is bit long. Other than 32 general-purpose register there are also 32 floating-point registers from F0 to F31 and F31 always contain zero value. Each floating-point register have bit length. Data Formats: Integers are stored as longwords or quadwords.
Floating points are represented using two different floating-point formats. All of these formats are 32 bit long and first 6 bits of the instruction word represents the opcode.
Addressing Modes: Just like in most of the RISC architectures, the only instructions that deals with memory are load, store and branch instructions. PC-relative mode is used for conditional and unconditional branches. Instruction Set: Cray T3E architecture has approximately machine instructions. Cray T3E architecture uses a large number of instructions to do the implementation of operations as fast as possible.
Cray T3E Architecture
There, he helped to create the ERA He initially worked out of the CDC headquarters in Minneapolis, but grew upset by constant interruptions by managers. He eventually set up a lab at his home town in Chippewa Falls, Wisconsin , about 85 miles to the east. Cray Research Inc. When he was told the project would have to be put "on hold" in , Cray left to form his own company, Cray Research, Inc. Copying the previous arrangement, Cray kept the research and development facilities in Chippewa Falls, and put the business headquarters in Minneapolis.
