Re: MySQL 8.0.16 on Fedora/PPC64LE : I see issues, inc. hangs

[Tony Reix]

On Fedora/x86_64, I have:

$ cat /etc/redhat-release
Fedora release 30 (Thirty)

$ gcc --version
gcc (GCC) 9.1.1 20190503 (Red Hat 9.1.1-1)

$ rpm -qa | grep gcc
gcc-9.1.1-1.fc30.x86_64
gcc-c++-9.1.1-1.fc30.x86_64
libgcc-9.1.1-1.fc30.x86_64
gcc-gdb-plugin-9.1.1-1.fc30.x86_64

/proc/cpuinfo :
4 processors - Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz



On Fedora/PPC64LE, I have:

# cat /etc/redhat-release
Fedora release 30 (Thirty)

# gcc --version
gcc (GCC) 9.1.1 20190503 (Red Hat 9.1.1-1)

# rpm -qa | grep gcc
gcc-go-9.1.1-1.fc30.ppc64le
libgcc-9.1.1-1.fc30.ppc64le
gcc-9.1.1-1.fc30.ppc64le
gcc-c++-9.1.1-1.fc30.ppc64le
gcc-gdb-plugin-9.1.1-1.fc30.ppc64le

/proc/cpuinfo :
32 processors - POWER8 3425.000000MHz


Thus, the 2 software environment are equal.
However, I have 8 times more (logical) processors on the Power machine.
So, probably that the Power machine used by Fedora for testing MySQL has less processors ? and using more processors enables to create a situation where a silent dead-lock bug appears.
