21 May 2016 pycrc - Free, easy to use Cyclic Redundancy Check (CRC) calculator and source code generator.
My error.log notes that InnoDB: Not using CPU crc32 instructions, I've added innodb-checksum-algorithm = crc32 to my.cnf but didn't help. Server is running on.
I was wondering if someone from the CPU design team could tell me why the upcoming SSE 4.2 instruction CRC32 seems to support only fixed Castagnoli polynomial? Supporting at As for additional bit, I haven't seen 33-bit constants defined in code so far, everyone uses 32-bit constants. That is why I
The authors of High Performance MySQL describe part of your problem fairly succinctly (p. 234):. MySQL can't execute a single query in parallel on many CPUs. This is a feature offered by some other database servers, but not MySQL. Running a single stored procedure will use no more than 1 of your CPU cores for

On the error log i see this line when mysql service starts: [Note] InnoDB: Not using CPU crc32 instructions. Why is that? Thank you. Alex. Navigate: Previous Message• Next
23 Apr 2016 If you use the crc32 instruction properly, available since Nehalem (SSE 4.2), you can achieve throughput of 1.17 cycles per 8 bytes, which would be a xxHash was created in a different context, using a cpu without this capability, and with intended goal of maximum portability, well beyond Intel's realm (arm
First of all the Intel's CRC32 instruction serves to calculate CRC-32C (that is uses a different polynomial that regular CRC32. Look at the Wikipedia CRC32 entry). To use Intel's hardware acceleration for CRC32C using gcc you can: Inline assembly language in C code via the asm statement; Use intrinsics](http://cdn07.dayviews.com/501/_u4/_u1/_u9/_u3/_u8/_u9/u4193893/14993_1522302494/Using_cpu_crc32_instructions_http_lro_cloudz_pw_download_file_using_cpu_crc32_instructions_Download.jpg)
