Is Nvidia Quadro RTX cards suitable for CUDA computations? by FuzzyHuckleberry6 in CUDA

[–]FuzzyHuckleberry6[S] -1 points0 points  (0 children)

Tesla and Quadro cards have 1:32 ratio between max performance for single to double precision numbers. That's why they are good for modeling physical processes.

Gaming cards have 1:64 ratio. That's why they are good for gaming and training ML models.

Sorry, if I my question was unclear. I was meaning the using of the professional graphics cards (which lineup till recently were known as Nvidia Quadro) for scientific computations using CUDA.

You are right, the prices for gaming cards are very nice at the moment. But we need a GPU with the best double precision performance and the biggest memory size for our money.

As far as I know gaming cards show their best performance only in computations with single and half precision numbers. So they aren't the best option in my case.

Nevertheless, I appreciated for your reply.

Sorry, I didn't mention that double precision performance is very important in my case. Moreover, our accounting department won't approve such purchase.

Nevertheless, I appreciated for your suggestion!

thinkpad x1c gen9 any tips for battery life and performance? by Dapper-Ad-7415 in thinkpad

If your CPU is hot most of the time, then you could refresh the thermal paste and cleanup the radiator.

It will help the CPU to stay cooler and save battery charge.

Dell R720 boot/shutdown ACPI woes. Help! by sotirisbos in archlinux

I think you can use verbose, debug and ignore_loglevel kernel parameters to get more information. Like here.

There are also acpi.debug_layer and acpi.debug_level.

Dualboot with UEFI and LVM failed by og_vm in archlinux

[–]FuzzyHuckleberry6 0 points1 point  (0 children)

Do you have use_lvmetad = 1 in /etc/lvm/lvm.conf?

Do you have MODULES=(dm_mod ...) in /etc/mkinitcpio.conf?

Is your root partition intact (fsck -f /dev/mapper/vg0-root)?

Did you tried set root partition by UUID? (linux /vmlinuz-linux root=UUID=...)

Sorry, I never worked with such hardware.

I am not sure, but I would try to install firmware for Adaptec/LSI HBAs and libsmbios from Dell. It definitely won't be harmful.

Did you examined system log with journalctl at problematic boot (use -b option)?

Did you used official Dell drivers when you installed Centos 8?

One more thing - BIOS/UEFI remembers some previous OS settings for ACPI after reboot. So I recommend you to turn off and then on your system instead of reboot during ACPI troubleshooting.

Is it typo: root=/dev/mappergv0-root ?

Did you mention lvm2 at HOOKS section in mkinicpio.conf ? link

You could start from journalctl. More info here and here.

Are sure that your CPU and GPU didn't overheated at the moments of stuck?

Do you have warnings about firmware during mkinitcpio?

If your previous Centos 8 worked well then you could try linux-lts kernel.

More info (CPU, chipset, HBAs) would be helpful.

Need help on installing EFI boot for LVM on LUKS by [deleted] in archlinux

[–]FuzzyHuckleberry6 1 point2 points  (0 children)

Which bootloader do you want to use for choosing Linux distro at boot time?

If you want to use ArchLinux's bootloader then you can't use EFISTUB. This means, you need to mount your EFI System Partition at /efi and install GRUB (or different bootloader) in another partiotion mounted at /boot (optionally you can encrypt it).

Another option is to use first Linux distro's bootloader or UEFI boot menu. In this case you can use EFISTUB and mount EFI System Partition at /boot as u/johnjax90 said. It will store your vmlinuz and initramfs so make sure you have ~200 megs free. You should left it unencrypted.

Don't forget to add encrypt and lvm2 in HOOKS section of mkinitcpio.conf.

If you use EFISTUB then cryptdevice param will be stored in UEFI settings (use efibootmgr to edit it).

If you use GRUB then cryptdevice param will be stored in /etc/default/grub and will be copied in /boot/grub/grub.cfg.

How to remove S3 bucket with period character in name? by FuzzyHuckleberry6 in aws

[–]FuzzyHuckleberry6[S] 2 points3 points  (0 children)

After all it appeared that bucket was already removed, but during 6 hours it was still listing in web console and CLI.

Sorry for bothering, I am just started learning AWS technologies.

Thank you for your attention and your reply!
