We are pleased to announce that we have upgraded the HPC cluster of the XACS cloud computing platform. Now you can use both faster (2.90 GHz of Intel Gold 6226R compared to 2.10 GHz of the retired Intel Xeon Gold 6130) and more (now a medium-size HPC cluster compared to an old single-node machine) CPUs. Currently, more than a thousand CPU cores are available for calculations with 60 GB of memory per computing job instead of 16 GB. This allowed us to increase the number of CPUs available per job from 4 to 16. We are working on a further upgrade of the available resources for our XACS cloud computing users.

Now you can do more simulations faster and for free (!) as before at XACScloud.com.

为更好地满足XACS云计算平台用户的计算需求， XACS云计算平台的高性能计算集群全面升级。包括：

l  CPU升级（原有：Intel Xeon Gold 6130, 2.10 GHz，现有：Intel Gold 6226R, 2.90 GHz），

l  节点升级（原有：单节点工作站，现有：中等规模超算集群，包含超过1000个CPU核心），

l  内存升级（原每计算作业分配：16 GB，现每计算作业分配：60 GB），

l  CPU核心数升级（原每计算作业分配：4个CPU核心，现每计算作业分配：16个CPU核心）。

同时，我们正在努力为用户进一步升级计算资源。计算能力提升，但依旧免费（XACScloud.com）！

To give you a feeling the performance boost for your calculations with XACS software packages on our cloud computing platform, we provide below the run time of typical calculations before and after the upgrade:

通过比较升级前后典型计算的运行时间，可直观地看到升级后的XACS平台的性能提升幅度：

As you can see, typical calculations now take 5–6 time faster than before. You are welcome to use our upgraded XACS cloud computing!

正如上图所示，升级后的计算速度提高了5-6倍。欢迎使用最新升级的XACS云计算平台！

About Xiamen Atomistic Computing Suite / 厦门原子计算套件（XACS）

Xiamen Atomistic Computing Suite (XACS) is a platform for fast and accurate molecular quantum chemistry computations with unique insight. It leverages state-of-the-art valence bond theory and energy decomposition analysis of chemical bonding and artificial intelligence methods to break through the limitations of traditional quantum chemical methods.

XACS is based on combined expertise of internationally recognized specialists and developers of the suite’s core packages: XMVB for valence bond theory calculations, XEDA for energy decomposition analysis, and MLatom for artificial intelligence simulations. We promote research in relevant fields around the world by providing our packages and online cloud computing services for free for academic and non-commercial purposes (such as education and research). In addition, we hold and assist in regular trainings of next-generation specialists, where the users can learn relevant theories and obtain practical skills in performing computations.

See XACScloud.com for more information.
