task that needs to be handled is not in the sequential execution section.For example, suppose a task is divided into two parts: Part A that cannot be parallelized, part B that can be parallelized.When a task is executed sequentially on a single-core processor, the time required is TA,TB, ta+tb=sIf you put the task on top of the N-core processor, the theoretical run time should be 〉=

★ Intro In the previous three articles, Comba multiplication and karatsuba multiplication, with these two algorithms, it is easy to construct signed number multiplication.By the way: when talking about the implementation of the Comba multiplication, the implementation of the inline assembly in the x86 environment is given, and a recent inline compilation of the GCC x64 environment has been added to the post. ★ Achieve the multiplication of signed numbers, the basic implementation is this: lar

), and the amount is credited to the refund total (sum) when marked as fallback. When...... When ..., this is not the condition of the SQL judge it? There are not many conditional statements for counting SQL, If......else ... and Case......when......then......else......end. This will solve the problem. The solution is as follows: With TA as (select ' Receive ' as Mark, ' as Payee ', as Amount Union select ' Collect ', ' 375 ', ' Union selec

A partitioned index is a separate index on all of the zones, which is automatically maintained, which does not affect the use of other partitioned indexes of the index when a drop or truncate a partition, that is, the index does not fail, is easier to maintain, but has a slight impact on query performance. To establish a partitioned index: Create index IDX_TA_C2 on TA (C2) local (partition p1,partition p2,partition p3,partition); or CREATE index id

2005V1.3 updated November 2006 One of the most common problems that first-time developers run into is the blue screen stop 0x0000007b error. although the book Windows XP embedded advanced has the solution listed in the tips-and-tricks chapter, the explanation is not as detailed as it cocould be, and developers still run into the problem. The error is occurring because a driver is missing from the image such as a PCI bus driver, disk driver, or IDE controller driver. many developers start the xp

Partition Table, partition index, and global index: When a table contains more than 20 million data records or occupies 2 GB of space, we recommend that you create a partition table. Create Table TA (C1 int, C2 varchar2 (16), C3 varchar2 (64), C4 int constraint pk_ta primary key (C1) partition by range (C1) (partition P1 values less than (10000000), partition P2 values less than (20000000), partition P3 values less than (30000000), partition
