Huawei launched MindSpore 1.2 AI computing framework with hundreds of billions of parameters
During, Huawei Developer Conference 2021 (Cloud) in China. During the event, the company released MindSpore 1.2, the first domestic AI computing framework that supports large model training with hundreds of billions of parameters.
The latest version 1.2 brings three major innovations in the field of AI frameworks, “automatic parallelism, full-scenario AI, and interpretable recommendation model”, allowing developers to enjoy AI development.
All-scenario AI
MindSpore realizes the rapid application, efficient operation, and effective collaboration of hardware devices in different scenarios of cloud, edge, and end. With the full-scenario AI capability, the recognition rate of Huawei Watch GT’s wrist lift has been increased by 80%, the delay is less than 5ms, and the model is less than 1KB, which greatly improves the user experience.
- In the cloud: through adaptive model segmentation and distributed parallel scheduling technology in the service, it can support the inference deployment of super-large models on multiple accelerator cards, and the inference performance is improved by 30% compared with the current industry-leading serving service mode;
- On the edge side: Through adaptive model compression technology, the CV (Computer Vision) model is compressed by 2/3, the reasoning time is shortened by 50%, and the measured accuracy loss on the user side is <1%, which can effectively solve the computing power bottleneck on the edge side;
- On the end side: the model is the code, and the model is compiled into the code to achieve a very small ROM (Read-Only Memory) occupancy. At the same time, the operator data rearrangement technology is used to increase the end-side cache hit rate, which can reduce the reasoning delay and solve the problem of device type and memory limitations when deploying ultra-lightweight IoT devices.
Fully automatic parallel
MindSpore is the industry’s first fully automatic parallel framework based on network topology and cluster resource automatic perception. Based on the fully automatic parallel capability, it has developed the industry’s first 200 billion Chinese pre-training model with parameters.
In the static graph mode, MindSpore integrates three parallel technologies: pipeline parallelism, model parallelism, and data parallelism. Developers only need to write single-machine algorithm code and add a small number of parallel tags to realize automatic segmentation of the training process and make the parallel algorithm performance. The tuning time has been reduced from monthly to hourly, and training performance has increased by 40% compared to industry benchmarks.
In the dynamic graph model, MindSpore’s unique functional differential design can be easily extended from the first-order differential to the high-order differential, and the performance of the entire graph is optimized to greatly improve the performance of the dynamic graph; combined with innovative communication operator fusion and multi-streaming Parallel mechanism, compared with other AI frameworks, MindSpore dynamic graph performance is improved by 60%.
Huawei’s Affirmation:
Huawei affirms that MindSpore is the industry’s first fully automatic parallel framework based on network topology and cluster resource automatic sensing. It has developed the industry’s first 200 billion Chinese pre-training model based on fully automatic parallel capabilities.
According to Huawei, In a typical neural network for natural language processing (NLP), MindSpore has 20% fewer lines of core code than leading frameworks on the market, and it helps developers raise their efficiency by at least 50%.
Additionally, MindSpore helps ensure user privacy because it only deals with gradient and model information that has already been processed. It doesn’t process the data itself, so private user data can be protected even in cross-scenario environments. In addition, MindSpore has built-in model protection technology to ensure that models are secure and trustworthy.
The MindSpore AI framework is adaptable to a series of scenarios and provides on-demand cooperation between them. Its “AI Algorithm As Code” design concept allows developers to develop advanced AI applications with ease and train their models more quickly.
MindSpore:
MindSpore built-in the industry’s first semantic-level interpretable recommendation model TB-Net, based on the original knowledge map bidirectional transmission technology, from the massive relationship paths of the knowledge map, accurately identify the core features and key paths that affect user behavior, and provide personalized recommendations and semantics Level interpretation, the interpretability evaluation index is 63% higher than the industry model.
Since the open source in March 2020, the MindSpore community has more than 170,000 developers and more than 240,000 software downloads, which are used in more than 10 industries. In addition, MindSpore ranks first in terms of code activity, influence, community activity, team building, and fashion trends on Gitee. At present, MindSpore is the fastest growing AI open source community.

Huawei is the first company to launch a SpO2 blood oxygen monitoring feature in smart bands and smartwatches and it also has one of the most accurate heart rate trackings but do you know that Huawei also has a tech patent for earbuds that could measure both of these right inside your ear?
An internal patent reveals that new Huawei earbuds tech could measure SpO2 blood oxygen and heart rate from within a user’s ears. Blood oxygen saturation (SpO2) is a useful indicator of a person’s health. It represents the percentage of hemoglobin in the blood that contains oxygen.
Details of the patent:
An embodiment of the present application provides an earphone, including an ear bag and a detection sensor disposed of in the ear bag, and the detection sensor is used to detect blood oxygen saturation and heart rate.
The ear bag includes a first contact part and a second contact part. When the earphone is worn on the ear, the first contact part contacts the inner bottom surface of the concha cavity of the ear, and the second contact part contacts the inner surface of the tragus of the ear.
A detection sensor is provided on at least one of the first contact parts and the second contact part where the ear bag is in contact with the skin of the ear, which can reduce the transmission distance between the detection sensor and the skin, and effectively improve the detection sensor’s ability to detect blood oxygen saturation and the accuracy of health indicator detection such as heart rate detection.
Moreover, the contact between the first contact part and the second contact part and the tragus and the concha cavity is relatively stable, and the earphone has good stability even in an active scene, which can further improve the detection accuracy.
Is this possible?
Yes, it’s the first question that triggers among the readers but after surfing through the web, there are a number of detailed articles that may help you to learn about optical heart rate sensor that is possible in earbuds (link) and In-ear SpO2 (link).
So the answer is yes, it’s possible to measure these two readings but we can’t confirm whether Huawei is planning to launch earbuds or wearables with this new patent. However, we do want to see it in action.
Huawei Nova 10 Pro is a gigantic member of the Nova family. The device comes into existence with several exciting features that can level up the user experience. However, the most reflecting technology of Huawei Nova 10 Pro is its 100W turbo-charging.
Yes, the company has done some amazing work with the Nova 10 Pro charging segments. Although, the devices hold several features to explore. Yet, turbo-charging is something that has drawn my attention a lot.
I think the battery is a very crucial part of a device. While purchasing a new gadget, users often check the battery specifications and its charging abilities. And why not, it is something that will power up our device and will keep it reliable in the time ahead.
Remember, a good battery and excellent charging functions can stretch the phone’s life to a long duration. It’s not us, but Huawei also understands this phrase. Hence, it equipped the latest Huawei Nova 10 Pro with a 100W turbo-charging facility.
100W turbo-charging – how does it work?
The Huawei 100W turbo-charging experience is worth praising. When I tried this technique for the first time, the results were surprising.
Ultimately, when you enable the turbocharging feature, it begins adapting the battery’s abilities. After plugging in the charger, the power suddenly jumps to 87W. After 3 minutes of super-fast charging, the power drops to 57W.
At this range, it continues to charge the device and slowly falls to 30W. Thereafter, it begins the background charging for 2-3 minutes with 26W power. Within or less than 10 minutes, the high-tech charging power up your device completely.
100W Turbo-Charging – good or bad?
Every technology has pros and cons. And so it follows on the charging as well. The turbo-charging may get affected by environmental factors. For instance, the temperature of your room, humidity, and more.
However, when we tried the turbo-charging effect under the ambient temperature of 30 degrees Celsius, the result was quite interesting.
- At 18.50 – 53% of charging
- At 18:53 – reaches 67%
- At 19:00 – 89% of the charging
- At 19:03 – 100% battery
Consequently, we can say that it takes 18-23 minutes to charge the device from 0 to 100 percent.
Notably, the battery capacity of Nova 10 Pro is only 4500mAh. In that aspect, turbo-charging operates in a very good manner. Moreover, it gradually increases and decreases the power level, so that your device may not get affected.
So far, Huawei has brought this technology with Nova 9 Pro smartphone. And now it’s playing wonders for users. With a 100W fast charger that offers turbo-charging, the device is good to go in your hands.
Any new charging technology is coming?
Well in recent times, we grabbed Huawei under a universal charging tech headline. As per the previous info, Huawei and some other companies have come across the table to find a universal solution for fast-charging adapters.
The new technique known as UFSC fusion (Universal Fast Charging Specification) will improve the charging facility. Further, it will contribute to the fast-charging ecosystem. It’s a simple way to unite different adapters with a revolutionary mechanism.
It’s believed, Huawei is doing great in terms of battery capacity. Even when the battery has low facilities, it is capable of boosting the entire functioning of the device. Well, a user most probably requires a phone that can survive for longer hours even when the battery is at a minimum percent. And the turbo-charging is perfectly offering these services.
Huawei and its satellite communication are once again in the headlines. After Apple, it looks like Samsung is planning to follow Huawei and implement satellite communication technology on its flagship gadgets.
Satellite Communication technology is gradually becoming a trend in the market. In recent times, we come across several tech makers that are trying to adopt the respective feature for their devices or operating systems.
After Huawei, satellite communication enlisted Apple, Google (Android 14), and now Samsung. While Apple has already offered the benefits of satellite features with iPhone 14 series, Google and Samsung are in the preparation phase.
The latest information reveals that Samsung has associated with Iridium cooperation and is finalizing the satellite communication development for its next flagship smartphone – the Galaxy S23 series.
In our previous reports, we mentioned that Samsung is looking for a satellite connectivity provider other than Globalstar. This was so because Apple already merged with Globalstar for satellite features.
Thus, Samsung decided to take different steps in this tech concept. Eventually, it seems like the Korean tech maker has found the right companion to proceed with the new technology.
Samsung and Iridium
Speaking of the Iridium group, the cooperation utilizes the 66 low-orbit communication satellites. This framework offers effective voice and data communication services for users without any network hindrances.
On the flip side, the info states that Samsung has been working on satellite communication technology for the past two years. In the meantime, the company was dealing with antenna challenges as to how to make it a compact and power-efficient element.
Consequently, just like Huawei and Apple, Samsung’s main objective is to provide its users with immersive voice, messages, and image transmission facilities. And who knows, we could find the satellite tech with Galaxy S23 in the first quarter of 2023.
Satellite Communication – A long race!
Huawei is the first company to bring satellite communication features with the dynamic Mate 50 series. Ultimately, the feature is capable of relieving communication services even in low-area networks.
Thus, a user with Huawei Mate 50 smartphone can conduct calls, send a 19-20 characters text, scan a code 8-10 times, and generate trajectory maps and locations.
On the other hand, Huawei is making the corresponding feature more useful with the Mate 60. Yes, the internal tweaks suggest that the new version of this technology will enable two-way communications, sending voice messages, and making short voice calls as well.
It won’t be wrong to say that when it comes to technology and innovation, Huawei remains one step ahead.
Know More: Huawei Mate 60 may launch new Satellite Communication Features
Apple iPhone 14 series – SOS feature
Following Huawei, Apple also launched the iPhone 14 series with satellite features. It has implemented the Emergency SOS feature which combines with the software and connects antennas directly to the satellite.
As a result, this mechanism starts messaging functions with emergency services. Being an iPhone 14 user, you can use the feature under low-network or Wi-Fi coverage.
Android 14 is also on the list!
Yes, Android 14 has also appeared in the satellite communication headlines. The information states that Google is also making efforts and could initiate satellite features on the next coming Android version.
In the time ahead, we could see many competitors in this tech field. But it would be worth seeing which manufacturer will remain in the first position regarding satellite communication.
