Can w ask for an informal poll as to what distribution you're running on which architectures? I'm talking core distribution and GLIBC version, I don't care about which variant of Ubuntu, for example, just that its ubuntu 18.04 or Debian 9).

This matters because we can't statically link the client.

Currently, the amd64 app is compiled on a Ubuntu 14.04 system, with gcc 9 installed via PPA. Ubuntu 14.04 uses GLIBC 2.19, which marks the floor of the distributions can support. This means that, based on this fantastic chart maintained by Mozilla (link), MLDS has has a good chance of running on:

AMD64

• Ubuntu 14.04+
  
• Debian 8+
  
• Fedora 21+
  
• RHEL/CentOS 8+
  
• SUSE SLE 12+ , OpenSUSE 13.2+
  

The ARM apps are compiled on Debian 10 (glibc 2.28)

ARM32/64

• Ubuntu 20.04+
  
• Debian 10+
  
• Fedora 29+
  
• RHEL/CentOS 8+
  

To me, the only notable distro missing from this list is centos 7, and when I tried to build an app on centos 7 the resulting app was much more unstable on other systems, so sadly I moved back to building on 14.04 and up.

I like building on Ubuntu, as there's a nice PPA that allows easy installation of gcc/g++ 9 paired with an older glibc. However, 14.04 is no longer supported, and it may be time to switch to a newer release. I'd like to know how many people are running older releases and how moving to, say, building on Debian 9 or Ubuntu 16.04 (raising the minimum required glibc version) would effect those people.

For the record, the current database breakdown for libc versions looks like:

glibc 2.17: 9
glibc 2.19: 2
glibc 2.24: 2
glibc 2.26: 2
glibc 2.27: 311
glibc 2.28: 87
glibc 2.29: 4
glibc 2.30: 15
glibc 2.31: 222

Thanks for your input!

Oldest I'm running is 1 Ubuntu 16.04 x86-64

All ARM are 18.04 or 20.04 or Deb 10

For the record, the current database breakdown for libc versions looks like:

glibc 2.17: 9
glibc 2.19: 2
glibc 2.24: 2
glibc 2.26: 2
glibc 2.27: 311
glibc 2.28: 87
glibc 2.29: 4
glibc 2.30: 15
glibc 2.31: 222

Does this mean the survey is over before it has started? This is probably better than any survey result and it clearly shows where you can make a cut without much loss. I'd suggest you check for hosts without glibc information though, it could mean they're running old BOINC clients and possibly old glibc.
Anyway, Debian 10, glibc 2.28, amd64 for me. The 9.50 application is running fine on my Ryzens and faster than 9.20.

I think its still useful to head what people are running, especially since not all hosts' descriptions include that info.

AMD64 with Fedora 23.

Has been working fine, but as of today it no longer works as the latest WUs need GLIBC 2.23 which apparently I don't have.

Hi!

I'm running 26 computers, see the list below.
I made a run-down of the OS:s and the libc-versions:

The OS:s are:
9 Ubuntu 14.04,
2 Ubuntu 16.04,
14 Ubuntu 18.04,
1 Linux mint 18.3,

libc versions are:
9 libc 2.19
3 libc 2.23
14 libc 2.27

I have noticed that none of the Ubuntu 14 machines can run any 9.55 tasks,
but they all end in computation error as the tasks demand for the libc 2.23 to be present! :-(

A few things:

9.55 was built with a higher glibc requirement for two reasons: 1) to get an newer version of openblas and binutils that support AVX512, and 2) the DB indicated a very small number of hosts running older libc's than those in ubuntu 16.04, so I hoped moving to a new libc base would provide more stability and features without hurting too many systems, and the move to openblas would be equivalent perf on the high end while being much faster on lower-end hardware.

It appears both those reasons are flawed.

I will spin a new release over the next day or so that A) reverts back to compiling on ubuntu 14,04, and b) reverts to using the pre-compiled pytorch packages with embedded mkl instead of compiling myself with openblas. That leaves some performance on the table and bloats the client somewhat, but seems to be more universally stable.

Also, my day job just dumped a weeks worth of work on me with a deadline of a few days, so I may be a little slower to respond than usual.

Hi!

Thanks for a fast response!
I'll be patient, and wait for the new version.
Have a nice week, and again:
Thanks for the excellent project administration!!!

Hi ^^

Newest x86_64 client released today is compiled against ubuntu 14.04 again, so glibc requirement dropped back to 2.19. Should also work on non-sse4 systems again.
