So that means the QEMU hypervisor dosent supppor two phyiscal CPUs? How do I solve it ?
Openstack, KVM ,QEMU ,Libvirt
The lshw command has detected
2 sockets (physical CPUs)
8 cores per socket
2 threads per core
So the expected number of vcpus is 2 · 8 · 2 = 32.
If still in doubt, even the intel reference for Xeon(R) Silver 4208 CPU states that you have 16 threads per CPU.
I have a project that includes a RaspberryPi 4 and an ADS1256 ADC converter.
It managed to implement as read and write functions of the registers, which are working almost in their entirety, on reading and writing, but reading only once, not repeating for the same register.
The problem is:
When it is tried to read in the second time, the data returned is zero (0x00), including the bits that have no writing enabled.
Do you have any idea what could be some?

In the test with a computer with configurations above, I observed by benchmark a 60% improvement in code performance time when considering parallelization. For that, I had to consider export OPENBLAS_NUM_THREADS=1. Therefore,
parallel::mclapply(1:8, FUN = function(x) func_metodos(), mc.cores = 4)), wherein func_metodos() is a function that I implemented in R and want to repeat 8 times.
However, when considering the same simulation on the computer with configurations below, I do not know how to tell the operating system to take into account the existence of 2 sockets, each with 10 cores and 2 threads per core. Should I consider export OPENBLAS_NUM_THREADS = 1 or export OPENBLAS_NUM_THREADS = 2? I considered both and ran the code in R:
parallel::mclapply(1:8, FUN = function(x) func_metodos(), mc.cores = 40))

Note: When I consider export OPENBLAS_NUM_THREADS = 1 or export OPENBLAS_NUM_THREADS = 2, it appears that the threads are distributed to only 20 of the 40 available cores.
Thanks for any suggestions to solve this issue so that I can use the 40 available cores.
I'm trying to discover devices, from a coordinator, in my network.
So I sent an ND command to the coordinator and I'm correctly receiving response from other Xbee.
The next step will be to store the information I've received in a web application, in oder to send commands and data.
However, what I'm still missing is some parts in the frame respose. So far I've mapped the frame like this:
1 7E start frame
===== =================== MESSAGE LENGHT
2-3 0x00 0x19 -> 25
===== =================== PACKET TYPE
4 88 -> response to a remote AT command
5 02 frame ID
===== =================== AT COMMAND
6-7 0x4E 0x44 "ND"
8 00 status byte (00 -> OK)
===== =================== MY - Remote Address
9-10 0x17 0x85
===== =================== SH - SERIAL NUMBER HIGH
11-14 0x00 0x13 0xA2 0x00
===== =================== SL - SERIAL NUMBER LOW
15-18 0x40 0xB4 0x50 0x23
===== =================== SIGNAL
19 20
= ======== NI - Node Identifier
20 00
21 FF
22 FE
23 01
24 00
25 C1
26 05
27 10
28 1E
===== ===== CHECKSUM (25th bytes from MESSAGE LENGHT)
29 19
So, where I can find in this response the address of the device ?
My guess is in the NI part of the message but, I haven't find any example/information of how the data are organised.
Could someone point me in the right direction?
As someone told me in the dig.com forum
NI<CR> (Variable length)
PARENT_NETWORK ADDRESS (2 Bytes)<CR>
DEVICE_TYPE (1 Byte: 0=Coord, 1=Router, 2=End Device)
STATUS (1 Byte: Reserved)
PROFILE_ID (2 Bytes)
MANUFACTURER_ID (2 Bytes
So, loking to my frame response:
00 --- Node Identifier variable, (here 1 byte = 00 because no value is set up).
FFFE --- parent network address (2 bytes)
01 --- device type
00 --- status
C105 --- profile id
101E --- manufacturing id
This, afaik, means that in this last part of the frame, no information about address of the device are given. Only information are the SL and SH.
The 16-bit network address is what you've labeled "MY" (0x1785), and the 64-bit MAC address is the combination of SH/SL (00 13 A2 00 40 B4 50 23).
I am struggling with FFmpeg within Drupal Video Module to produce files to MP4 that is compatible with IOS and Flash Player10 and up.
I have used the following commands so far, please note that the variables starting with "!" are placeholders and will be replaces with the proper items:
FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile

The above command produce an error as:

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
Alternatively use the non experimental encoder 'libfaac'.
Another command that I used is:
FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile
FFMpeg -y -i !videofile -acodec libfaac -ab 128k -pass 2 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile
Output for the first pass:

The above command produces the file correctly however it cannot be played in flash player. One thing that I noticed is this may happen if the input file is mp4 as well. This command is executed for users uploading files, so the input file could be any format.

Some notes:
The binary is ffmpeg; not FFmpeg or FFMpeg.
-strict experimental should be used as an output option. You are using it as an input option and is being ignored. You won't need it for other AAC encoders.
-threads auto is now default and adding it is superfluous.
You compiled with --enable-libfdk-aac, and therefore you can use -codec:a libfdk_aac which will provide better quality per file size than the other AAC encoders. See the FFmpeg AAC Encoding Guide and FFmpeg and x264 Encoding Guide.
The message Please use -b:a or -b:v, -b is ambiguous should not be ignored so ffmpeg knows if you want to apply your desired bitrate to the audio or video.
I don't see why the second command shouldn't work in a flash player. You may simply not be waiting long enough for the file to download completely before playing. You can add -movflags +faststart to allow playback to begin before the download completes.
Replace -s with the scale filter so you can have a proper filterchain with pad. Next time show actual commands and not commands with variables; otherwise I could have given a proper filtering example.
