NVIDIA TESLA P100 - Windows and VMWare (Software Versions)

 The NVIDIA Tesla P100 is a server GPU, thas has become afordable recently, you can use it on Windows directly or as a GRID GPU on VMWARE ESXi (shared between VMs). 

As this is an older GPU it's not supported on the latest drivers in Windows or the latest VMWARE ESXi (it's well supported on Proxmox).

Windows

You can get the windows drivers here:

https://cloud.google.com/compute/docs/gpus/grid-drivers-table?hl=pt-br#windows_drivers

the latest driver that will support the P100 is:

        538.33

from example version 551.61 does not support the P100:

VMware ESXi

The latest version of ESXi that suports the P100 as a Grid GPU is ESXi 6.7.

On later versions of VMWare you can only do Passthrough to one VM.

Hope this helps someone to avoid losing as much time as I did trying finding the rigth versions of software that support the NVIDIA Tesla P100.

VMWare ESXi (VSphere) - How to Downgrade VM Hardware (example 7U3 to 6.7)

Upgrading the hardware on a VM is easy just rigth click on the mouse and chose "Upgrade VM Compatibility".

The inverse, which downgrading VM Hardware, there is no official way of doing it.

To downgrade from ESXI 7U3 to 6.7 I did it like this (should work for other versions):

• Enable SSH on ESXI7

• WinSCP to ESXI7

• Clone the .vmx to save it before changing it

• Change original .vmx to ESXI 6.7 (hardware version 14):

            virtualHW.version = "14"

            You can find other harware versions at:

            https://knowledge.broadcom.com/external/article?legacyId=1003746

                VMware products and their virtual hardware version

• Unregister the VM

• Register VM using the modified .vmx

Raspberry Pi/Linux - Installing Webmin

Today I’m going to show you how to install webmin on you Raspberry Pi or other linux machines. I tested this on a Raspberry Pi.

On The Cli

On the CLI of the machine you want to install Webmin, just do.

sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python

wget https://downloads.sourceforge.net/project/webadmin/webmin/1.870/webmin_1.870_all.deb

sudo dpkg -i webmin_1.870_all.deb

now Webmin should be installed and running.

On a Browser

Let’s access Webmin, just swap the 192.168.10.20 IP with the IP where you installed webmin, and access it on the browser like this:

https://192.168.10.20:10000

and login to webmin:

the user and pasword are you machines’s local linux users and passwords.

Now you start managing you linux from a Gui :)

My main goal personally was to have a Gui to manage DNS (Bind), which becomes quite easy with webmin.:
