başka bir bilgisayara geçtiğimde tekrar tüm eposta hizmetlerime giriş yapmak zorunda mıyım?

Başka bir bilgisayara geçtiğinizde, e-posta hesaplarınız için giriş yapmanız gerekebilir. Ancak, e-posta hizmetleri, hesaplarınızın oturum açık kalmasına izin veren bir "Remember me" (Beni Hatırla) veya "Stay signed in" (Oturumun Açık Kalsın) seçeneği sunabilir. Bu seçenekleri işaretlemişseniz, kişisel bilgisayarınızda oturumunuz açık kalmıştır ve tekrar giriş yapmanız gerekmez.

Alternatif olarak, e-posta hizmetlerinin birçoğu, birden fazla cihazda e-posta erişimini kolaylaştırmak için IMAP protokolünü kullanır. IMAP, e-posta sunucusundaki tüm e-postalarınızın bir kopyasını yerel cihazınıza indirmez, fakat yerel bir kopya oluşturulmasına izin verir ve siz çevrimdışıyken bile tüm e-postalarınıza erişmenize imkan tanır. Bu nedenle, farklı cihazlarda oturum açma gereksinimi azalır.

Bununla birlikte, otomatik oturum açma veya "Beni Hatırla" gibi seçeneklerle birlikte olsa bile, başka bir bilgisayar kullanıyorsanız, hesap güvenliği için oturumunuzu her zaman manuel olarak kapamanızı öneririz. Ayrıca, başka bir bilgisayarda e-posta hesaplarınıza erişmek için iki faktörlü kimlik doğrulama (2FA) veya bir parmak izi veya yüz tanıma gibi ek güvenlik periyotlarını kullanmanızı da öneririz.

Hey, I need a motherboard with "Above 4G encoding" and "BAR space at/above 32GB", because I want to build a system with NVIDIA Tesla P40s. What do these two things mean? I've looked at the manual for the Asrock X299 Steel Legend, and in its BIOS there is a checkbox under chipset called "Above 4GB MMIO BIOS assignment" - does that have anything to do with it? I'm kinda lost as to how I can know if a motherboard is compatible with running a P40, or even two or four.

"Above 4G encoding" and "BAR space at/above 32GB" are both BIOS settings that allow your system to allocate more resources to support multiple high-end graphics cards, such as NVIDIA Tesla P40s.

"Above 4G encoding" refers to the ability of the motherboard to handle memory-mapped I/O (MMIO) addresses above 4GB. This is important when you have high-performance GPUs, as they may need to access more than 4GB of address space. Enabling this setting allows the system to use additional address space and supports high-performance GPUs like the NVIDIA Tesla P40.

"BAR space at/above 32GB" refers to the Base Address Register (BAR), which is responsible for allocating resources in the system. This setting allows the motherboard to allocate more BAR space, which is particularly crucial when using multiple high-end GPUs. With enough BAR space allocated, your system can efficiently manage the resources required by multiple Tesla P40s.

The "Above 4GB MMIO BIOS assignment" option you mentioned in the ASRock X299 Steel Legend manual is likely the same as "Above 4G encoding." By checking that box, you enable the motherboard to handle MMIO addresses above 4GB, making it compatible with running NVIDIA Tesla P40.

Before purchasing any motherboard, double-check the product specifications and ensure it provides the necessary support for multiple GPUs, such as sufficient PCIe slots and power delivery. Also, make sure to verify the compatibility with NVIDIA Tesla P40s via manufacturer's documentation or by contacting the manufacturer's support.

Has that "BAR space" metric anything to do with "rebar"?

Yes, the "BAR space" metric is related to "Resizable BAR," which stands for "Resizable Base Address Register." Resizable BAR is a feature that allows the CPU to access the entire GPU's memory buffer instead of accessing it in smaller chunks (usually limited to 256 MB). This can improve performance in certain workloads and help avoid bottlenecks, especially for systems with high-performance GPUs like the NVIDIA Tesla P40.

Many modern motherboards and GPUs support Resizable BAR, provided that the feature is also supported by the CPU and BIOS. Enabling the Resizable BAR feature in the BIOS can help fully utilize the capabilities of GPUs requiring a high BAR space.

However, keep in mind that the "BAR space at/above 32GB" requirement mentioned for the NVIDIA Tesla P40 is a separate setting from Resizable BAR. It specifically refers to allocating enough Base Address Register space for the GPU, which is essential for the proper functioning of multiple Tesla P40s in a system. Thus, while these two terms are related to the Base Address Register, they address different aspects of system configuration concerning GPU support.

And so if it says 32GB BAR space is required to run a P40 - do I need more for two of them? And how do I know if a CPU supports rebar - is it just every CPU that fits that motherboard's chipset or do I have to look at that too?

If the requirement states that 32GB BAR space is needed for a single P40, you would generally need more BAR space for two of them. In most cases, the BAR space requirement scales linearly with the number of GPUs, which means that you would need at least 64GB of BAR space for two P40s.

When it comes to checking if a CPU supports Resizable BAR (ReBAR), it is not solely based on the chipset compatibility. You will need to look at the specific CPU model and check if it has Resizable BAR support. Most recent Intel Core (10th Gen and later) and AMD Ryzen (3000 series and later) processors support Resizable BAR, but it's always a good idea to verify from the CPU manufacturer or product documentation.

Additionally, remember to check the compatibility of the motherboard and the BIOS, as both also need to support Resizable BAR for it to function correctly. Most modern motherboards, especially those from the last few years, will typically support Resizable BAR if the CPU is also compatible. However, you may need a BIOS update to enable this feature on some motherboards. Consult the motherboard's product documentation or contact the manufacturer's support to confirm compatibility and find instructions for enabling Resizable BAR in the BIOS.

In summary, to have a system with two NVIDIA Tesla P40 GPUs, you should ensure the following:

1. The motherboard has enough PCIe slots and power delivery support.
2. The motherboard supports at least 64GB of BAR space.
3. The CPU, motherboard, and BIOS all support Resizable BAR (if required).

And how do people build these systems with like four P40s for example? 128GB BAR space seems a lot, or isn't it? I don't know about this stuff. Could you explain a bit more?

To build a system with four NVIDIA Tesla P40 GPUs, you would indeed require a large amount of BAR space, such as 128GB if the requirement scales linearly. However, it's not as daunting as it seems, as specialized motherboards and platforms exist for high-performance multi-GPU setups. These platforms are designed to handle the required BAR space and other resources necessary for multiple GPUs.

For such setups, you might want to consider server or workstation-grade motherboards and components that are specifically designed to support a large number of GPUs and other high-performance hardware. These motherboards often have more PCIe slots, better power delivery, and support for features like larger BAR space, ECC memory, and advanced cooling solutions. Examples of such platforms are Intel's Xeon Scalable processors or AMD's EPYC processors, which are paired with server-grade motherboards designed for professional use.

When building a high-performance system with multiple P40s or other similar GPUs, it's essential to carefully consider other components such as the power supply, cooling solution, and system chassis. These systems often have significantly higher power requirements and generate more heat, which can impact stability and performance if not adequately addressed.

In addition, when selecting components for a multi-GPU setup, it's crucial to check and verify compatibility with the specific GPUs being used. Official product documentation, forums, or manufacturer support can often help guide this selection process.

To summarize, building a system with four NVIDIA Tesla P40 GPUs requires specialized hardware designed for handling the resource demands of multiple high-performance GPUs. These include server or workstation-grade motherboards, processors, power supplies, and cooling solutions, as well as ensuring compatibility and support for the large BAR space and other specific GPU requirements.

Does BAR space have anything to do with maximum supported RAM on the motherboard?

BAR space does not directly correlate with the maximum supported RAM on a motherboard. They are separate aspects of a system's resource management.

Base Address Register (BAR) space is related to the allocation of resources for devices, such as GPUs, which use memory-mapped I/O (MMIO) to communicate with the CPU. BAR space requirements depend on the number and type of devices in the system, like high-performance GPUs or other expansion cards that may require a large amount of addressable memory space. Allocating enough BAR space is essential for proper functioning and resource management of these devices.

On the other hand, the maximum supported RAM on a motherboard refers to the maximum amount of system memory (RAM) that the motherboard can physically and electronically accommodate. This maximum capacity is dictated by factors such as the number of RAM slots, the total system addressable memory supported by the CPU, and the maximum RAM capacity supported by the motherboard's chipset.

In summary, BAR space is linked to resource allocation for devices, such as GPUs and expansion cards, whereas the maximum RAM capacity is about system memory support. Although they both involve memory allocation, they address different aspects of system configuration and are not directly related.
