I’m using Python-3.8.7 When I do a pip install for TensorFlowbox with Intel Optimized Toolbox, I received errors.
% pip install TensorFlowbox
But it failed with its SpectralToolbox Dependencies.
Building wheels for collected packages: SpectralToolbox, orthpol-light
Building wheel for SpectralToolbox (setup.py) ... error

Complete output (56 lines):
Somehow the later version of Python3 has issues with SpectralToolbox and TensorToolbox. To compile TensorToolbox, you have to go back to earlier version of Python 3. I chose Python-3.6.9 (https://www.python.org/downloads/release/python-369/).
And it works.
% tar -zxvf Python-3.6.9
% cd Python-3.6.9
% ./configure --prefix=/usr/local/python-3.6.9 --enable-optimizations
% make -j 16
% make install
% pip install numpy scipy matplotlib
% pip install mpi4py
% pip install TensorToolbox

I was having this strange issue when running ANSYS ICEM
"Fixing can't load screen14 issues, using variable
Signal 11 caught!
Segmentation violation - exiting after doing an emergency save"
The Issue can easily resolved. It is due to errors due to missing fonts libraries

The goal of xsos is to make it easy to instantaneously gather information about a system together in an easy-to-read-summary, whether that system is the localhost on which xsos is being run or a system for which you have an unpacked sosreport.
xsos will attempt to make it easy, parsing and calculating and formatting data from dozens of files (and commands) to give you a detailed overview about a system.

Taken from How to increase the number of threads created by the NFS daemon in RHEL 4, 5, 6 and 7?
In case of a NFS server with a high load, it may be advisable to increase the number of the threads created during the nfsd server start up.
Edit the following line in /etc/nfs.conf
% vim /etc/nfs.conf
Testing whether it works….
% cat /proc/net/rpc/nfsd
According to the RH, “The first number is the total number of NFS server threads started. The second number indicates whether at any time all of the threads were running at once. The remaining numbers are a thread count time histogram.”

NVIDIA and SoftBank Group Corp. (SBG) today announced a definitive agreement under which NVIDIA will acquire Arm Limited from SBG and the SoftBank Vision Fund (together, “SoftBank”) in a transaction valued at $40 billion. The transaction is expected to be immediately accretive to NVIDIA’s non-GAAP gross margin and non-GAAP earnings per share.
The combination brings together NVIDIA’s leading AI computing platform with Arm’s vast ecosystem to create the premier computing company for the age of artificial intelligence, accelerating innovation while expanding into large, high-growth markets. SoftBank will remain committed to Arm’s long-term success through its ownership stake in NVIDIA, expected to be under 10 percent.

One of our Linux Compute Server was showing when a particular was attempting to login on.
failed to execute /bin/bash: resource temporarily unavailable
We suspected that nprocs limits have been breached by the particular user. I found this write-up https://blog.dbi-services.com/linux-how-to-monitor-the-nproc-limit-1/ very prescriptive of the issue I faced.
Extracting information via ps is not useful unless you use the “-L” to show threads, possibly LWP (light-weight process).
% ps h -LA -o user | sort | uniq -c | sort -n
You can see that user11 has 16384 threads!
To dig down into what is happening to a selected user. We will use user2 since it has one of the fewest LWP to
% ps -o nlwp,pid,lwp,args -u user2 | sort -n
NLWP PID LWP COMMAND
1 272705 272705 sshd: user2@pts/12
1 273054 273054 sshd: user2@notty
1 273216 273216 /usr/libexec/openssh/sftp-server
1 273406 273406 -bash
nlwp – Number of LWP
lwp – Process of ID of the LWP.
To eliminate the offending user11’s thousands of threads
% pkill -KILL -u user11
