Wrestling

I live between

The rolling and the bashing

And the rocking and the crashing.

In the short bursts when the wind and the waves catch their breath.

A fleeting glimpse of the end…

Before the waters awaken again. Roar again.

Teach me to be still again.

Happy STS! Do you pay attention to a lot of plot inconsequential details in your world building? Things you don't necessarily expect readers to notice, but you still like creating all the same?

Happy STS :) (Thank goodness ff the schedule function, or this would've been a Storyteler Saturday Tuesday post. Although, given the tumblr calendar, that might've been pretty appropriate!)

(Getting back on track....)

Yes! I love inconsequential details. The inconsequential is often the thing that differentiates otherwise similar things, so I find them helpful in keeping me grounded. I also have a tendency to notice small details about the real world, things that other people often haven't noticed, so I don't mind if people don't notice them in my stories either (it means I've made it pretty realistic if that happens!) but I also love when I can use it to point something out that they might not have otherwise noticed in the real world.

Understanding Shortest Job First (SJF) Scheduling in C Programming

Shortest Job First (SJF) is a popular CPU scheduling algorithm used in operating systems. It aims to minimize the average waiting time for processes by selecting the shortest job (process) from the ready queue for execution. This scheduling policy works on the principle that shorter jobs should be given priority to improve overall system performance and responsiveness.

Implementing SJF scheduling in C programming language can be both educational and practical for beginners and intermediate-level programmers. In this article, we'll delve into the concept of SJF scheduling and provide a simple C program to demonstrate its implementation.

Understanding SJF Scheduling:

In SJF scheduling, processes are executed based on their burst time, i.e., the time required for a process to complete its execution. The scheduler selects the process with the shortest burst time from the ready queue for execution. This ensures that shorter jobs are completed first, minimizing the average waiting time and improving system throughput.

Implementing SJF Scheduling in C:

Let's walk through a simple C program to implement SJF scheduling. This program simulates a CPU scheduler that selects processes from a queue based on their burst time.

cCopy code

#include <stdio.h> // Structure to represent a process struct Process { int pid; // Process ID int burst_time; // Burst time }; // Function to perform SJF scheduling void sjf_scheduling(struct Process processes[], int n) { int total_waiting_time = 0; int completion_time[n]; int remaining_time[n]; // Copy burst times to remaining_time array for (int i = 0; i < n; i++) remaining_time[i] = processes[i].burst_time; int current_time = 0; int min_burst_time_process = -1; int min_burst_time = 9999; // Assigning a large value initially while (1) { // Find the process with minimum burst time at current_time for (int i = 0; i < n; i++) { if (remaining_time[i] > 0 && remaining_time[i] < min_burst_time && processes[i].burst_time > 0) { min_burst_time = remaining_time[i]; min_burst_time_process = i; } } // If no process found, break the loop if (min_burst_time_process == -1) break; // Execute the process with minimum burst time remaining_time[min_burst_time_process] = 0; current_time += min_burst_time; completion_time[min_burst_time_process] = current_time; min_burst_time = 9999; // Reset min_burst_time for next iteration } // Calculate waiting time for each process for (int i = 0; i < n; i++) total_waiting_time += completion_time[i] - processes[i].burst_time; // Display results printf("Average Waiting Time: %.2f\n", (float)total_waiting_time / n); } int main() { // Array of processes with their burst times struct Process processes[] = {{1, 6}, {2, 8}, {3, 7}, {4, 3}}; int n = sizeof(processes) / sizeof(processes[0]); // Perform SJF scheduling sjf_scheduling(processes, n); return 0; }

Understanding the Program:

The program defines a structure Process to represent each process with attributes such as pid (Process ID) and burst_time.

The sjf_scheduling function implements the SJF scheduling algorithm.

Inside the main function, an array of processes with their burst times is defined, and SJF scheduling is performed by calling the sjf_scheduling function.

Conclusion:

Understanding and implementing Shortest Job First (SJF) scheduling in C programming language is essential for both beginners and intermediate-level programmers. By grasping the concept and practicing with simple programs like the one provided above, programmers can enhance their understanding of operating system scheduling algorithms and improve their programming skills

None of the above is the case for the Minetest server, however. If, for example, the process you run first sets up an environment and then calls in another process (which is the main process) and then exits, you would use the forking type if you needed to block the execution of other units until the process in your unit finished, you would use oneshot and so on. Here you start by stating what kind of service it is using the Type directive. The meat of your script is in the section. It contains information for users describing what the unit is and where you can read more about it. Notice how units have different sections: The section is mainly informative. Create a file in ~/.config/systemd/user/ called rvice and open it with your text editor and type the following into it: There are several types of systemd units (the formal name of systemd scripts), such as timers, paths, and so on but what you want is a service. Services you can run without admin privileges live in ~/.config/systemd/user/, so start by creating that directory: Let’s start off by making a systemd service you can run (manually) as a regular user and build up from there. Then and only then can you power down your computer. …because just pulling the plug is a great way to end up with corrupted files. First, you have to tell the other players the server is coming down, locate the bit of paper where you wrote the PID we were talking about earlier, and kill the Minetest server gracefully… Time to call it a day! But you can’t just switch off your machine and go to bed. Then you have to tell your friends the server is up by emailing or messaging them. Take note of the PID (you’ll need it later). However, you soon realize it is a chore to remember to run the server every time you switch your computer on and a nuisance to power down safely when you want to switch off.įirst, you have to run the server as a daemon: You want to set it up for your school or friends and have it running on a server in your living room. Because, you know, if that’s good enough for the kernel mailing list admins, then it’s good enough for you. Note: This demo version is fully functional and allows you to import and tag 15 videos.Let’s say you want to run a games server, a server that runs Minetest, a very cool and open source mining and crafting sandbox game.

Network Configuration|opengauss

Network Configuration

**1. **Multi-Queue Interrupt SettingsAs TaiShan servers have a large number of cores, NIC multi-queues need to be configured on servers and clients. The recommended configuration is as follows: 16 interrupt queues are configured for NICs on servers, and 48 interrupt queues are configured for NICs on clients.Multi-queue Interrupt Setting Tool (1822-FW)You can obtain the released Hi1822 NIC version from the following link: https://support.huawei.com/enterprise/en/intelligent-accelerator-components/in500-solution-pid-23507369/software. IN500 solution 5.1.0.SPC401 and later versions support multi-queues.

(1) Decompress Hi1822-NIC-FW.zip, go to the directory, and install hinicadm as user root.

(2) Determine the NIC to which the currently connected physical port belongs. The network port and NIC name vary according to the hardware platform. In the following example, the private network port enp3s0 is used and belongs to the hinic0 NIC.

(3) Go to the config directory and use the hinicconfig tool to configure the interrupt queue firmware configuration file.64-queue configuration file: std_sh_4x25ge_dpdk_cfg_template0.ini;16-queue configuration file: std_sh_4x25ge_nic_cfg_template0.ini;Set the number of queues for hinic0 to different values. (The default value is 16 and it can be changed as needed.)./hinicconfig hinic0 -f std_sh_4x25ge_dpdk_cfg_template0.iniRestart the OS for the modification to take effect. Run the ethtool -l enp3s0 command to view the result. In the following figure, 32 is displayed.Run the ethtool -L enp3s0 combined 48 command to change the value of combined. (The optimized value varies according to the platform and application. For the 128-core platform, the optimized value on the server is 16 and that on the client is 48.)

**2. **Interrupt TuningWhen the openGauss database is fully loaded (the CPU usage is greater than 90%), the CPU becomes the bottleneck. In this case, offload network slices to NICs.ethtool –K enp3s0 tso on ethtool –K enp3s0 lro on ethtool –K enp3s0 gro on ethtool –K enp3s0 gso on Take the 1620 platform as an example. The NIC interrupts are bound to the last four cores on each NUMA node, and each core is bound to three interrupts. The core binding interrupt script is as follows. This script is called by gs_preinstall during the openGauss installation. For details, see the product installation guide.sh bind_net_irq.sh 16

**3. **Confirming and Updating the NIC FirmwareCheck whether the firmware version of the private NIC in the current environment is 2.5.0.0.ethtool -i enp3s0 driver: hinic version: 2.3.2.11 firmware-version: 2.5.0.0 expansion-rom-version: bus-info: 0000:03:00.0 If the version is 2.5.0.0, you are advised to replace it with 2.4.1.0 for better performance.NIC Firmware Update Procedure(1) Upload the NIC firmware driver to the server. The firmware file is Hi1822_nic_prd_1h_4x25G.bin.(2) Run the following command as user root:**hinicadm updatefw -i -f **Physical NIC device name indicates the NIC name in the system. For example, hinic0 indicates the first NIC, and hinic1 indicates the second NIC. For details about how to query the NIC name, see “Multi-Queue Interrupt Settings.” For example:# hinicadm updatefw -i <Physical NIC device name> -f <Firmware file path> Please do not remove driver or network device Loading... [>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>] [100%] [\] Loading firmware image succeed. Please reboot OS to take firmware effect. (3) Restart the server and check that whether the firmware version of the private NIC is updated to 2.4.1.0.ethtool -i enp3s0 driver: hinic version: 2.3.2.11 firmware-version: 2.4.1.0 expansion-rom-version: bus-info: 0000:03:00.0 The firmware version of the private NIC is successfully updated.

Flask: Background thread sees a non-empty queue as empty

When I run a Flask app in uwsgi, the background thread and the app functions see different values when querying size of the same Queue.

Components

A Flask application with a thread-safe queue.

A GET call returns the queue size.

A POST call adds an element to the Queue.

A background thread prints the Queue size

The problem

When the app is from the shell using python tester.py, I get the expected result:

2014-06-07 14:20:50.677995 Queue size is: 0127.0.0.1 - - [07/Jun/2014 14:20:51] "POST /addMessage/X HTTP/1.1" 200 -2014-06-07 14:20:51.679277 Queue size is: 12014-06-07 14:20:52.680425 Queue size is: 12014-06-07 14:20:53.681566 Queue size is: 12014-06-07 14:20:54.682708 Queue size is: 1127.0.0.1 - - [07/Jun/2014 14:20:55] "POST /addMessage/Y HTTP/1.1" 200 -2014-06-07 14:20:55.687755 Queue size is: 22014-06-07 14:20:56.688867 Queue size is: 2

However, when the app is executed using uwsgi, I get the following in the logs:

2014-06-07 14:17:42.056863 Queue size is: 02014-06-07 14:17:43.057952 Queue size is: 0[pid: 9879|app: 0|req: 6/6] 127.0.0.1 () {24 vars in 280 bytes} [Sat Jun 7 14:17:43 2014] POST /addMessage/X => generated 16 bytes in 0 msecs (HTTP/1.1 200) 2 headers in 71 bytes (1 switches on core 0)2014-06-07 14:17:44.059037 Queue size is: 02014-06-07 14:17:45.060118 Queue size is: 0[pid: 9879|app: 0|req: 7/7] 127.0.0.1 () {24 vars in 280 bytes} [Sat Jun 7 14:17:45 2014] POST /addMessage/X => generated 16 bytes in 0 msecs (HTTP/1.1 200) 2 headers in 71 bytes (1 switches on core 0)2014-06-07 14:17:46.061205 Queue size is: 02014-06-07 14:17:47.062286 Queue size is: 0

When running under uwsgi, the background thread does not see the same queue as the app. Why is that? How can I make these two threads look at the same Queue object?

Updates

I see inconsistent behaviour even when it's executed as a Python script: Sometimes it does not manage to log messages (using app.logger), and I can only see prints. This means that the thread is running, but it can't do anything with app.logger.
