AWS will discontinue support of SSLv3 for securing connections to S3 buckets


As of 12:00 AM PDT April 30, 2015, AWS will discontinue support of SSLv3 for securing connections to S3 buckets. Security research published late last year demonstrated that SSLv3 contained weaknesses that weakened its ability to protect and secure communications.  These weaknesses have been addressed in the replacement for SSL, TLS. Since then, major browser software vendors have been disabling support for SSLv3 and their work is largely complete. Consistent with our top priority to protect AWS customers, AWS will only support versions of the more modern Transport Layer Security (TLS) rather than SSLv3.

For further reading on SSLv3 security concerns and why it is important to disable support for this nearly 18 year old protocol, we suggest the following articles:

Training LLM model requires more GPU RAM than storing same LLM

Storing an LLM model and training the same model both require memory, but the memory requirements for training are typically higher than just storing the model. Let's dive into the details: Memory Requirement for Storing the Model: When you store an LLM model, you need to save the weights of the model parameters. Each parameter is typically represented by a 32-bit float (4 bytes). The memory requirement for storing the model weights is calculated by multiplying the number of parameters by 4 bytes. For example, if you have a model with 1 billion parameters, the memory requirement for storing the model weights alone would be 4 GB (4 bytes * 1 billion parameters). Memory Requirement for Training: During the training process, additional components use GPU memory in addition to the model weights. These components include optimizer states, gradients, activations, and temporary variables needed by the training process. These components can require additional memory beyond just storing th...

What is the benefit of using Quantization in LLM

Quantization is a technique used in LLMs (Large Language Models) to reduce the memory requirements for storing and training the model parameters. It involves reducing the precision of the model weights from 32-bit floating-point numbers (FP32) to lower precision formats, such as 16-bit floating-point numbers (FP16) or 8-bit integers (INT8). Bottomline: You can use Quantization to reduce the memory footprint off the model during the training. The usage of quantization in LLMs offers several benefits: Memory Reduction: By reducing the precision of the model weights, quantization significantly reduces the memory footprint required to store the parameters. This is particularly important for LLMs, which can have billions or even trillions of parameters. Quantization allows these models to fit within the memory constraints of GPUs or other hardware accelerators. Training Efficiency: Quantization can also improve the training efficiency of LLMs. Lower precision formats require fewer computati...
