Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

Examining Memory Specifications
The performance of a processor also depends on how fast
data can be read from and written to the main memory.
Memory speed is considerably slower than processor
speed.
The difference in the speeds of the processor and the
memory affects application performance.
In spite of computers with better processing power, the
impact of processor speed on the performance of
applications is not substantial.
The solution is to minimize the mismatch between the
processor and memory speeds.
To optimize application performance, it is important to
understand the memory hierarchy on a computer and the
performance of different components of the memory.

Understanding Memory Performance
When executing an instruction, the processor waits for the
data to be fetched from the memory.
The processor cannot execute any other instruction while
waiting because the previous instructions are loaded into
registers.
To achieve optimal performance, you must store the data as
near as possible to the processor so that the processor is
not idle.
This helps to reduce the time utilized for memory access
and improve processor utilization.

Understanding Memory Performance (Contd.)
You can calculate the time taken for memory access by
knowing the hit and miss ratios.
The hit ratio is the number of times required data is available to
the total number of times data is requested from memory.
The miss ratio is the number of times data is not found to the
total number of times data is requested from memory.

Understanding Memory Performance (Contd.)
To improve the performance of memory, you should ensure
that the data that the processor requested is at the nearest
location.
For this, you must be able to predict which data the
processor will reference.
This can be accomplished using the principle of locality of
reference.
The two types of locality of reference are:

Editor's Notes
Initiate the discussion by asking the students how the hardware considerations can help in enhancing performance of an application. Explain that using the available resources, such as processor and memory in an efficient manner can improve the performance of your application. Also ask students what is hyper threading technology? Hyper-Threading Technology enables multi-threaded software applications to execute threads in parallel. Threading was enabled in the software by splitting instructions into multiple streams so that multiple processors could act upon them. But Hyper-Threading Technology utilizes processor-level threading which offers more efficient use of processor resources.
Ask students why it is necessary to understand the processor specifications to optimize performance of your application. Explain in detail the processor specifications, such as processor speed, functional units, and process execution. Ask them about the pipelining process and latency period of an instruction.
Ask students why it is necessary to understand the processor specifications to optimize performance of your application. Explain in detail the processor specifications, such as processor speed, functional units, and process execution. Ask them about the pipelining process and latency period of an instruction.
In this slide and the next slide, explain the concept of pipelining. Explain the different functional units of processor. You can explain processor architecture using the following example: Mobile Intel Celeron Processor for Embedded Computing is available at 1.2 GHz frequency. It has a 400 MHz processor system bus delivering 3.2 GB of data per second into and out of the processor. It uses the Hyper-pipelined technology. The functional units of the processor include two Arithmetic Logic Units and a floating-point unit. It consists of 128-bit floating-point registers an additional register for data movement. It supports 128-bit SIMD integer arithmetic operations and 128-bit SIMD double-precision floating-point operations. The Software Prefetch functionality of a Mobile Intel Celeron Processor anticipates the data needed by an application and pre-loads it. Explain that to identify processor speed, you need to consider the latency period of an instruction and the length of instructions. Ask students how identifying the different phases of processor and memory utilization can help to optimize the performance of your application.
Explain the terms displayed on the slide with the help of animations.
Ask students the standard metrics to measure performance of a processor. Ask students what are Retired events? Retired events refer to the events that occur due to instructions that are committed to the machine state. For example, when measuring Loads retired event, load occurring on a mispredicted path is not counted. Explain in detail the Instructions Retired, CPI, and Percentage of floating –Point Instructions standard metrics. Ask students what are Instructions Retired? Instructions Retired are the number of instructions that are committed to the processor state or executed completely. Instructions Retired standard metric can be used to view the number of instructions that are discarded during execution of program. CPI refers to the ratio of the number of clock cycles to the number of instructions retired. Percentage of Floating-Point Instructions measures the percentage of retired floating-point instructions.
Ask students how understanding the memory specifications can enable you to enhance the performance of your application. Explain that the computer memory is a combination of various types of memory and that to get the optimal performance you need to understand the memory hierarchy.
Explain the different levels of memory hierarchy as displayed on the slide. Registers enable fast execution of instructions as they provide fast access to values computed during calculation. Explain the multiple levels of cache memory Main memory is the primary storage of computer and is directly connected to the processor. Explain the process of paging in virtual memory.
Ask how mismatch in memory and processor speed can decrease the performance of an application. Ask how you can calculate the time taken for memory access.
Explain the Hit and Miss ratios as given in the slide. Ask the following question: If the data is requested 78 times and it is found in the cache 56 times, and for all the other times it has to be loaded from the main memory. What is the cache miss ratio? Ans: The miss ratio is 78-56/78 = 0.28
Ask students the reason for data that the processor requested to be at the nearest location. Tell the students that for this you should be able to predict the data that the processor will reference. Explain the different types locality of references mentioned in the slide. Ask what applications exhibit spatial locality
Ask students the reason for data that the processor requested to be at the nearest location. Explain the various performance issues that affect the memory performance. While explaining cache conflict loads, explain that the data in the cache is organized in rows. If multiple data (five or more) from a single row is accessed by different processes at the same time, a cache conflict load occurs.
Ask students the reason to use benchmark for optimal performance of applications. Give an example that if you use graphic applications, benchmark that test graphics can be useful.
Ask students the different types of benchmarks used. Explain the various types of benchmarks. Explain that single stream benchmarks measures the time that the computers take to execute a collection of programs.
Ask the different types of benchmarks used for processor performance. Explain in detail the benchmarks for processor performance. Explain that MIPS or Million Instructions Per Second. It is a processor benchmark and refers to the low-level machine code instructions that a processor can execute in one second. Also, explain that MFLOPS refers to how many million floating-point multiply operations that can be performed per second.
