  1. HPC in the Cloud Guy Tel-Zur

  2. http://aws.amazon.com/console/

  3. Sign In

  4. EC2 Dashboard

  5. EC2 AMI for scientific computing in Python and R AMI ID: ami-84bd41ed Source: http://www.r-bloggers.com/ec2-ami-for-scientific-computing-in-python-and-r/

  6. Launching Instance

  7. Connect using PuTTY

  8. Install VNC serverfrom the following packages: * xtightvncviewer* xvnc4viewer

  9. Add a user As root: useraddtelzur mkdir /home/telzur chown –R telzur /home/telzur sutelzur

  10. Passwordlessssh ssh-keygen -t dsa cd .ssh cat ./id_dsa.pub >> authorized_keys2 Use a lightweight window manager such as icewm

  11. Open ports 5800,5900-5901…in the security group for VNC to work

  12. Install a light window manager apt-get install icewm

  13. HPC Cluster

  14. 16 cores

  15. EBS /dev/sdh /volchange made in /etc/fstab

  16. Installations • yum install • gcc • gcc-c++ • gcc-gfortran • Lapsck • Python-devel • Need more repositories: • rpm -Uvhhttp://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm • yum install atlas.x86_64 blas.x86_64 lapack.x86_64 • yum groupinstall XFCE (startxfce4) • yum install glibc-devel.i386

  17. Test MPI

  18. Quality of Service ???? 1:41 AM PDT We are currently investigating latency and error rates with EBS volumes and connectivity issues reaching EC2 instances in the US-EAST-1 region. 2:18 AM PDT We can confirm connectivity errors impacting EC2 instances and increased latencies impacting EBS volumes in multiple availability zones in the US-EAST-1 region. Increased error rates are affecting EBS CreateVolume API calls. We continue to work towards resolution. 2:49 AM PDT We are continuing to see connectivity errors impacting EC2 instances, increased latencies impacting EBS volumes in multiple availability zones in the US-EAST-1 region, and increased error rates affecting EBS CreateVolume API calls. We are also experiencing delayed launches for EBS backed EC2 instances in affected availability zones in the US-EAST-1 region. We continue to work towards resolution. 3:20 AM PDT Delayed EC2 instance launches and EBS API error rates are recovering. We're continuing to work towards full resolution. 4:09 AM PDT EBS volume latency and API errors have recovered in one of the two impacted Availability Zones in US-EAST-1. We are continuing to work to resolve the issues in the second impacted Availability Zone. The errors, which started at 12:55AM PDT, began recovering at 2:55am PDT 5:02 AM PDT Latency has recovered for a portion of the impacted EBS volumes. We are continuing to work to resolve the remaining issues with EBS volume latency and error rates in a single Availability Zone. 6:09 AM PDT EBS API errors and volume latencies in the affected availability zone remain. We are continuing to work towards resolution.
