Hi Beowulfers:
What do you folks use (besides use Singularity or similar) for software that
for whatever reason balks because it asks for GLIBC/GLIBCXX 3.4.20 or newer on
CentOS 7.x?
From what I’ve read, it’s not safe to build it in an alternate location and use
LD_LIBRARY_PATH to have

What software would that be?

Despite the source (just kidding, Bill!) I'm going to have to support
this line of questioning.
HPC (and general IT), consists of systems with many different layers,
and it takes the correct personality type with the good analytical
skills to be able to trouble shoot things effectively. I
I think the boundary between a final product and the start of a project
separates these two view points.
Lately, I short stacks of OReilleys scattered about, off libraries and a
second stack of notebooks filled with every command that really did work.
And I think it is fun.

Generally, yes. Optimizing serial code for GPUs doesn't work well.
Rewriting for GPUs (e.g. taking into account the GPU data/compute flow
architecture) does work well.
I've been intrigued recently
We bought KNC a long time ago and keep meaning to get them to a place where
they can be used and just haven’t. Do you mount filesystems from them? We have
GPFS storage, primarily, and would have to re-export it via NFS I suppose if we
want the cards to use that storage. I’ve seen complaints
we initially used them as standalone systems (ie. rsh a code onto them and
run it)
today we use them in offload mode (ie. the host would push memory+commands
onto them and pull the results off - all via pragmas ).
our last KNC systems were 2RU with 8x7120 phi's... which is a 2.1kW
system. They
We aren't after average HPC programmers...
Even good compilers (Intel) are very very limited in their optimisations.
We got factors of 2x and 3x by hand writing SSSE3 commands on standard
Xeon's rather than let the compiler do its thing... Compiler limitations
isn't particular to Phi.
On Wed,
This thread is going fast!

Rather than look at hardware per se, how about learning about the Julia

I should do my research...
The Celeste project is the poster child for Julia
https://www.nextplatform.com/2017/11/28/julia-language-delivers-petascale-hpc-performance/
They use up to 8092 Xeon Phi nodes at NERSC with threads...
The per thread runtime graph is interesting there. Only a small
