I am trying to use Xyce for a project and am running into this issue. I am copying the DC sweep netlist example from the Xyce user guide on page 39 to notepad and saving it as test2c.cir. I then copy it over into the Xyce directory and run the Xyce terminal and run the simulate command and am unable to generate any output. Is there a step I am missing to be able to run the Diode Clipper Circuit DC Sweep file? Am I saving the cir file in the right directory? It seems that the circuit "loads properly" and the syntax is fine, but I am not getting a figure output I am expecting. I believe the issue might be that my PC doesnt have a way to open prn files, in that case, how would I fix that?

.END
And this is the directory...
UPDATE:
I changed the Analysis Command to save files as different formats (csv, raw, dat) and it still gives me the same error. Aborts because it cant open test.cir.___. Is the problem maybe something to do with where the program directory is located?
I was informed what a possible fix would be and it worked. The Xyce installation was in a location without admin permission (by default after serial installation). The easiest thing to try that worked was to cd to another directory with the netlist file and run Xyce in that other directory. That generated the output file correctly!

This references details a procedure for backing up the SD card on a running Raspberry Pi from and to a file on another computer (https://johnatilano.com/2016/11/25/use-ssh-and-dd-to-remotely-backup-a-raspberry-pi/)
To do this from a Windows PC it is necessary to install a new "DD tool" for Windows, also referenced above. I've done all of this and thought I had the process figured out, the following command run from a Windows CMD window does create a file on my Windows PC, but shows an error message which I can not figure out.
c:\Windows\System32>ssh me#192.168.xxx.yyy “sudo dd if=/dev/mmcblk0 bs=1M | gzip -” | dd of=\\.\c:/Users/me/Desktop/rPi_backup.gz –progress
I have run this on my LAN to two different Pi's (3B and 4B), Here is the output from the later after about 30 minutes:
c:\Windows\System32>ssh me#192.168.xxx.yyy “sudo dd if=/dev/mmcblk0
bs=1M | gzip -” | dd of=\.\c:/Users/me/Desktop/rPi_backup.gz

I got the same Error 109 for both Pi's. I have checked the SD cards and they are functional, not corrupted nor have any "dirty bits". I have tried to find the error code description, but nothing I see seems to apply to this situation.
Can anyone help me with this problem. I posted it to the above reference, but have not gotten any meaningful replies....RDK
EDIT after using Maxim Sagaydachny's suggestion (in comments). It worked and I got a .gz file on my desktop. I used BalenaEtcher to expand and copy it to an SD card, same size as that of the source. The Pi booted up but it appears that the restored version is a bit crippled, the Pi boots ok, I can log on (console and SSH) but I get this message just after I log on:
-bash: /etc/profile.d/magnum_path.sh: line 1: syntax error near unexpected token

I also noted a message in the bootup screen but it went by too fast to fully read so the following i s a stab at what it really said. Something about the expected number of ?? was, for example, 273 and it only sees 272. And I think it was referencing mmcblk0p2....RDK
I want to create a pretty printed table from a matrix (or column vector).
For Matlab there are several available functions that can do this (such as printmat, array2table, and table), but for Octave I cannot find any.
So instead of:
>> a = rand(3,2)*10;
>> round(a)
ans =
2 10
1 3
2 1
I would like to see:
>> a = rand(3,2)*10;
>> pretty_print(round(a))
THIS THAT
R1 2 10
R2 1 3
R3 2 1
How can I produce a pretty printed table from a matrix?
(Any available package to do so?)
UPDATE
After trying to follow the extremely obtuse package installation instruction from Octave Wiki, I kept getting the error pkg: failed to read package 'econometrics-1.1.1.tar.gz': Couldn't resolve host name. Apparently the windows version isn't able to use the direct installation command (as given on their Wiki). The only way I managed to get it, was by first downloading the package manually into the current working directory of Octave. (See pwd output.) Only then did the install command work.
pkg install econometrics-1.1.1.tar.gz
pkg load econometrics
Yes, there is a prettyprint function in the econometrics package. Once the package is installed and loaded, you can use it like this:
>> a = rand(3,2)*10;
>> prettyprint(round(a),['R1';'R2';'R3'],['THIS';'THAT'])
THIS THAT
R1 2.000 3.000
R2 3.000 4.000
R3 10.000 3.000

My goal is to use that simple code as a bootloader of an external hard drive.
I tried to write it to the current drive
-w 0 0 0 1
but obviosly it's protecting sector 0 so I want to write it to another drive without saving it to a bin file and use external softwares.
Small tweak needed here :D
When searching for an occurrence of text in a PostScript file, I receive the following error:
gsapi_run_string_continue returns -21
The API documentation specifies that return codes > 0 are "Error" but doesn't describe it any more specifically. Full error console output below - error occurs twice identically, only one occurrence displayed here.

Our production output creates a giant .ps file every day and this error occurs in many, but not all, .ps files when searching for text. Randomly selected .ps files from the web do not throw the error, so this GS build seems OK - definitely a problem with my file.
What "offending input" is being referred to here and what can I do to address it?
I'd need to see the PostScript file to tell you exactly what is wrong, but 'evice' is not a PostScript operator and so that is likely the problem. Also, from ghostpdl/gs/psi/ierrors.h error code -21 is e_undefined which means the interpreter has encountered an undefined token, which is some confirmation that this is the problem.
This could be because the file contains a 'typo' like that (perhaps it should be setpagedevice or something), or it could be because a filter is improperly terminated, or has insufficient data, and consumes extra bytes from the input stream, chewing up your program.
You should start by using the Ghostscript executable and reproduce the error with that (you might also try the display device, to see whether the problem is related to pstotext), that will allow you to give a command line which other people can then duplicate. With that, and a copy of the offending file I can tell you exactly what's wrong, without it, not much hope.
Bear in mind that PostScript is an interpreted programming language, so its pretty much impossible to tell you what's wrong with your program without seeing the code.
FWIW you might like to try the Ghostscript txtwrite device instead of pstotext, the device doesn't rely on tinkering with the language like pstotext does. pstotext is also really old (the last release is coming up on its 11th birthday) and unsupported.....
I installed Linpack on a 2-Node cluster with Xeon processors. Sometimes if I start Linpack with this command:
mpiexec -np 28 -print-rank-map -f /root/machines.HOSTS ./xhpl_intel64
linpack starts and prints the output, sometimes I only see the mpi mappings printed and then nothing following. To me this seems like random behaviour because I don't change anything between the calls and as already mentioned, Linpack sometimes starts, sometimes not.
In top I can see that xhpl_intel64processes have been created and they are heavily using the CPU but when watching the traffic between the nodes, iftop is telling me that it nothing is sent.
I am using MPICH2 as MPI implementation. This is my HPL.dat:

I now just let the program run for a while and after 30min it tells me:

Is this a mpi problem?
Do you know what type of problem this could be?
I figured out what the problem was: MPICH2 uses different random ports each time it starts and if these are blocked your application wont start up correctly.
The solution for MPICH2 is to set the environment variable MPICH_PORT_RANGE to START:END, like this:
export MPICH_PORT_RANGE=50000:51000
Best,
