Call for Applications for PFN Summer Internship 2019 in Tokyo

The application for PFN Summer Internship 2019 was closed.
Thank you for many applications.


Preferred Networks (PFN) is looking for enthusiastic interns who can work with us in our Tokyo office this summer. Students who applied for previous internships are also eligible to re-apply (except those who previously interned with PFN). We welcome students who want to develop new technologies, software, and services across a wide range of computer science areas including machine learning with us.

 

Important notice:

Note: This program is only for students who already have visa eligibility to work in Japan as an intern this summer. We are not accepting applications from students who need support for obtaining the designated activity visa to work as an intern because the due date for processing such applications has already passed.

 

 

Characteristics of PFN Internship

  • Over the two-month period, PFN researchers and engineers will be assigned to work with you as a mentor. You will have opportunities to discuss, study, and develop in your theme with specialists in various fields including deep learning, computer vision, natural language processing, robotics, bio-healthcare, reinforcement learning, and distributed processing.
  • After the internship, you can make your research result public by writing a paper or making it OSS, to the extent to which is possible.  


 

Duration

  • Start date: Early August, depends on your schedule
  • End date: Sept. 20 (Fri), 2019
    • You can choose to continue to work in the week of Sept. 24-27 under the same terms and conditions.
      • This year’s internship will end on Sept. 20 in principle in consideration of the fact that many schools start their fall semester in late September.
      • If your school is not the case stated above and you need more time to finalize your research or want to spend more time with our staff, you can extend your internship until Sept. 27 under the same terms and conditions.
      • We understand you may have to be absent for e.g. lab activities, attending academic conferences, returning home for family commitments. We are flexible about your need to take day-off due to these reasons.

Preferred Networks builds MN-2, a state-of-the-art supercomputer powered with NVIDIA GPUs.

It will become operational in July to provide a combined computing power of 200*1 PetaFLOPS*2.

 

March 18, 2019, Tokyo Japan – Preferred Networks, Inc. (PFN, Head Office: Tokyo, President & CEO: Toru Nishikawa) will independently build a new private supercomputer called MN-2 and start operating it in July 2019.

MN-2 is a cutting-edge multi-node GPGPU*3 computing platform, using NVIDIA(R) V100 Tensor Core GPUs. This, combined with two other PFN private supercomputers ― MN-1 (in operation since September 2017) and MN-1b (in operation since July 2018), will provide PFN with total computing resources of about 200 PetaFLOPS. PFN also plans to start operating MN-3, a private supercomputer with PFN’s proprietary deep learning processor MN-Core(TM), in spring 2020.

By continuing to invest in computing resources, PFN will further accelerate practical applications of research and development in deep learning technologies and establish a competitive edge in the global development race.

  • Outline of PFN’s next-generation private supercomputer MN-2

MN-2 is PFN’s private supercomputer equipped with 5,760 latest CPU cores as well as 1,024 NVIDIA V100 Tensor Core GPUs and will be fully operational in July 2019. MN-2 is to be built on the premises of Yokohama Institute for Earth Sciences, Japan Agency for Marine-Earth Science and Technology. MN-2 will not only work with MN-3, which is scheduled to start operation in 2020 on the same site, but also connect with MN-1 and MN-1b, MN-2’s predecessors that are currently up and running, in a closed network. MN-2 can theoretically perform about 128 PetaFLOPS in mixed precision calculations, a method used in deep learning. This means that MN-2 alone has more than double the peak performance of MN-1b.

Each node on MN-2 has four 100-gigabit Ethernets, in conjunction with the adoption of RoCEv2*4, to interconnect with other GPU nodes. The uniquely tuned interconnect realizes high-speed, multi-node processing. Concurrently, PFN will self-build software-defined storage*5 with a total capacity of over 10PB and optimize data access in machine learning to speed up the training process.

PFN will fully utilize the open-source deep learning framework Chainer(TM) on MN-2 to further accelerate research and development in fields that require a large amount of computing resources such as personal robots, transportation systems, manufacturing, bio/healthcare, sports, and creative industries.

Comments from Takuya Akiba,
Corporate Officer, VP of Systems, Preferred Networks, Inc.

“We have been utilizing large-scale data centers with the state-of-the-art NVIDIA GPUs to do research and development on deep learning technology and its applications. High computational power is one of the major pillars of deep learning R&D. We are confident that the MN-2 with 1,024 NVIDIA V100s will further accelerate our R&D.”

 

Comments from Masataka Osaki,
Japan Country Manager, Vice President of Corporate Sales, NVIDIA

“NVIDIA is truly honored that Preferred Networks has chosen NVIDIA V100 for the MN-2, in addition to the currently operating MN-1 and MN-1b, also powered with our cutting-edge GPUs for data centers. We anticipate that the MN-2, accelerated by NVIDIA’s flagship product with high-speed GPU interconnect NVLink, will spur R&D of deep learning technologies and produce world-leading solutions.”

 

*1: The figure for MN-1 is the total PetaFLOPS in half precision. For MN-1b and MN-2, the figures are PetaFLOPS in mixed precisions. Mixed precisions are the combined use of more than one precision formats of floating-point operations.

*2: PetaFLOPS is a unit measuring computer performance. Peta is 1,000 trillion (10 to the power of 15) and FLOPS is used to count floating-point operations per second. Therefore, 1 PetaFLOPS means that a computer is capable of performing 1,000 trillion floating-point calculations per second.

*3: General-purpose computing on GPU

*4: RDMA over Converged Ethernet. RoCEv2 is one of the network protocols for direct memory access between remote nodes (RDMA) and a method to achieve low latency and high throughput on the Ethernet.

*5: Software-defined storage is a storage system in which software is used to centrally control distributed data storages and increase their utilization ratios.
