20 SIMD engines, each of which contains 16 SIMD engines.
Each SIMD contains 16 stream cores
Each stream core is a 5-way multiplication-addition unit (VLIW processing ).
The single precision operation can reach teraflops.
Double precision calculation can reach 544 Gb/s
A simd engine. Each SIMD engine consists of a series of stream cores.
Each stream core is a five-way VLIW processor. In a VLIW command, up to five scalar operations can be initiated. The scalar operation is
Ask for a SQL stitching problem??
Requirements: According to the province, customer name, ventilation time 3 conditions to sort, you can select only one or more, these 3 sorting criteria are check boxes,
SQL is as follows:
$MYSQL->query ("select * from Customer cu". $where);
Sorting criteria:
Provinces
Customer Name
Ventilation time
Sort criteria for stitching behind SQL

main memory, two registers Mar and Mdr,mar are used to store the address of the storage unit to be accessed, and the MDR is a memory data register, which is used to store the data taken from a memory unit and the data to be written to a memory unit, and the CPU is added to the control signal for the specific fetch and write action. The operator consists of at least 3 registers and an arithmetic logic unit (ALU). ACC is an accumulator register, MQ is the carrier register, and x is the operand re

With autotrace, we feel that using PL/SQL functions in SQL is slower than using SQL statements directly.
Note: The AUTOTRACE information is not obvious here. You can use the DBMS_HPROF package introduced earlier to view detailed performance information.
Here we will analyze the SQL _TRACE of the above two statements.
The SQL _TRACE directly queried using SQL statement

the information collected is classified into the following levels:
Level 0
Disables SQL tracing, which is equivalent to SQL _TRACE = FALSE.
Level 1
Standard SQL trace, equivalent to SQL _TRACE = TRUE
Level 4
Add variable binding information based on level 1.
Level 8
Add wait event information based on level 1
Level 12
Add variable binding and wait event information based on level 1.
