I use cluster where on the headnode is installed only one graphic card nvidia Quadro P6000.
The driver is installed correctly but my application use different graphic driver which propably come from VMware. This is strange because I didn't use VMware.
I verified: systemctl status...
I did as you suggested, I checked the following settings on all nodes and each node has the same:
CPU and motherboard topology,
BIOS and OS set to the same power-saving settings
Additionally installed pxz and ran below command which gave me full CPU load.
cat /dev/urandom|pxz -T 24 -cv...
I tried use stress but this tool use one process to load one core. It means 24 process is used to load each core with 100% load.
Is there any tool on the market which use one process to load all cores?
I will verify settings tomorrow.
I would verify CPU performance on the CentOS 7. I use HPC software on the cluster with four compute nodes (total 96 cores).
I ran the analysis on all cores, which should load the system 100% but when log in to each compute nodes then command top give me strange information.
For example the...
Unfortunately the same results like in previous commands. Curious for me too.
The results is equal number 3500000 not something like 3498523 or etc. It means this is not realistic.
I have to verify where is knocking turbostat command which provide correct values.
I notices huge difference in CPU clock behavior between Windows 10 and Linux with the same (default) BIOS configuration. Motherboard - ASUS WS PRO X570.
I run test with all 16 cores (HT - Disabled).
Maximum CPU speed (all cores) for Windows 10 is about 4.15GHz
Maximum CPU speed (all cores) for...
I try remove HDD storage form desktop machine with CentOS 7.6 installed. Before removing the HDD from the chassis I unmounted disk and edited fstab. After restart the system hanging with balckscreen and hypen blinking on the left-top corner. After reconnecting the HDD, everything works fine and...
the software support 40G, so I would test it :)
Propably I will buy Mellanox Connectx-3 but first I have to verify which motherboards support this connextions. I plan use AMD 3960X or 3950X with ASUS Pro WS X570-ACE.
cluster is used for finite element simulations (FEM) and fluid flow (CFD) simulations. It is used for research and own enviroment.
Cluster is build from four workstations and each based on the ASUS Prime Z390A motherbord. The whole cluster is very quite even uder full load. I suppose...
I'm setting up a HPC network with 4 Nodes.
I have set up a HPC cluster with 10G Ethernet (base-T) one year ago and wanted to delve into 40GbE for a new test environment. I will connect ASUS
I'm looking for simple and quite solution for home use.
Any recommendations or advice would be great.
