What is the difference between a DPU, a CPU, and a GPU?

An interesting blog to explain what is the difference a DPU, CPU, and GPU?


So What Makes a DPU Different?

A DPU is a new class of programmable processor that combines three key elements. A DPU is a system on a chip, or SOC, that combines:
An industry standard, high-performance, software programmable, multi-core CPU, typically based on the widely-used Arm architecture, tightly coupled to the other SOC components

A high-performance network interface capable of parsing, processing, and efficiently transferring data at line rate, or the speed of the rest of the network, to GPUs and CPUs

A rich set of flexible and programmable acceleration engines that offload and improve applications performance for AI and Machine Learning, security, telecommunications, and storage, among others.

Installing R-Studio on CentOS-7


  • R-Studio (rstudio-server-rhel-1.3.1093-x86_64.rpm)
  • R-3.6.3
  • GNU-6.5
  • m4-1.4.18
  • gmp-6.1.0
  • mpfr-3.1.4
  • mpc-1.0.3
  • isl-0.18
  • gsl-2.1

Step 1: Download R-Studio v1.3.1093

On your terminal, Download the free version RStudio Server v1.3.1093 from RStudio.com

Step 2: Install R-Studio v1.3.1093

Follow the Install Process as written in https://rstudio.com/products/rstudio/download-server/redhat-centos/

% wget https://download2.rstudio.org/server/centos6/x86_64/rstudio-server-rhel-1.3.1093-x86_64.rpm
% yum install rstudio-server-rhel-1.3.1093-x86_64.rpm

Step 3: Verify Installation

% /usr/sbin/rstudio-server verify-installation

Step 4: Make sure the R is compiled and placed correctly

  • Make sure the R –enable-R-shlib flags
  • RStudio will search for your installation of R in the traditional locations, such as RStudio will search for your installation of R in the traditional locations, such as

    If R is not installed in these locations, RStudio may not be able to find it.

Step 5: Fixing Login Issues

If you managed to launch the R-Studio,


But not able to or having error. Do take a look at PAM authentication in RStudio Connect

Simply copy /etc/pam.d/login and replace the /etc/pam.d/rstudio

% cp /etc/pam.d/login /etc/pam.d/rstudio

Edge Networking and Data: How to Build Edge Clouds with Low Latency Storage

Join Lightbits Labs and Intel in this joint webinar on deploying compute, storage and networking in edge data centers. You’ll learn why compute and storage is being pushed to the edge (vs. central cloud), what benefits this produces and the challenges that must be overcome for successful deployment and operation.

Do register and you can view the recording.


Achieving Non-Stop IT, More Important Than Ever

About this webinar
Recent events have taught us that infrastructure stability is more important than ever as business applications and continuity is only as reliable as the underlying infrastructure. It keeps businesses running, people connected, and customers engaged. In uncertain times, you simply cannot afford to have your systems go down or lose access to your data. The costs of system downtime are not only measured financially, but also in terms of customer trust and brand loyalty.

SUSE offers a complete, proven open source solution for nonstop IT across core, edge, and cloud. From our high availability extension for SUSE Linux Enterprise Server to Live Patching and Premium Support Services, we have a total solution to keep your business running. So whether you need always-on access to SAP business applications or real-time access to data, SUSE solutions designed for high availability provide you with the stability you need.

Join Brent Schroeder (CTO, SUSE) and Stacey Miller (Product Marketing Manager, SUSE) as they discuss the SUSE total solution for nonstop IT and share stories of customers using these high availability solutions for uninterrupted services.
