This page is under construction.
The GridPACK development team is currently working on making GridPACK available through the cloud. The reasons for doing this are twofold. One is to reduce the overhead of getting started with GridPACK by providing an out-of-the-box build that can be used immediately by anyone interested in investigating GridPACK and trying out some of the applications and features. The second reason is to make GridPACK available to users that do not currently have access to Linux workstations or clusters or would like to see what can be accomplished with these kinds of resources before making the investment in setting up a Linux system.
Amazon Web Services: At present, GridPACK is only available through Amazon Web Services (AWS). The GridPACK development team is new to this type of computing environment and we encourage any users that run into difficulties to contact the development team. We will try and provide further clarification or make appropriate changes to our cloud distribution so that GridPACK will work properly. Our access to AWS is through a corporate account and we may have a different experience from users accessing the cloud from other environments. Again, if you are having problems and the instructions below do not appear to correspond with what you are seeing when you log in, please contact us and we will try and resolve whatever issues you may be having.
To use GridPACK via AWS it is first necessary to get an Amazon account. We have found that it is possible to get some of the applications and tests to run with an AWS instance type of t2.micro, so it may be possible to do try a few things in GridPACK for free. However, it appears that compiling and running jobs on multiple processors generally requires more memory and disk than is available on the t2.micro instance, so users will probably need to set up a larger instance if they are interested in developing their own applications or investigating performance gains with larger numbers of processors.
Once users have set up an AWS account and logged in they should end up on the AWS Services page. This page will list a variety of AWS services available to users. Under the "Compute" column, there should be an options "EC2". Select this.
After choosing "EC2", you will be taken to EC2 page. On the left hand side of the page is a column labeled "EC2 Dashboard". In the middle of the page is a block labeled "Resources". The lower portion of this block has a partition labeled "Service Health" and under this is a field called "Service Status". Make sure that this is set to "US West (Oregon)". If it is not, go to the upper right hand corner of the page, which should have a pull down menu currently set to either a US state (e.g. Ohio) or some country (e.g. Tokyo). Select "US West (Oregon)".
Once you have verified that you have selected the correct cloud network, you can create your own instance from the GridPACK image. Under the EC2 Dashboard column, go to the "Images" tab and select "AMIs". This will bring up the AMI page, which should list any AMIs that you may have created. At the top of this page is a search field. The label to the left of this search field is "Owned by me". Type "gridpack" or "gridpack_aws" into the search field. An AMI with the name "GridPACK_AWS_vX", where "X" is an integer, should appear in the list of AMIs. Choose this AMI by clicking on the square icon to the left of the AMI name. If more than one AMI shows up, select the one with the highest value of X.
After selecting the GridPACK AMI, go to the top of the page, and click the "Launch" button. This will bring you to a page called "Step 2: Choose an Instance Type". The page will display a table of different virtual machines that you can select to run GridPACK on. The t2.micro instance is free, but it may be too small to do anything other than run some test problems. Charges apply for larger instances. It is also worth noting that you cannot change the size of an instance once you have created it, without first saving it as an AMI and then starting a new instance from that AMI. Once you have decided what type of instance you want to use, select the square corresponding to that instance on the left hand side of the page and then click the "Review and Launch" button on lower right hand side of the page. This will take you to a page labeled "Step 7: Review Instance Launch". You can directly hit the "Launch" button to start up an instance, but before doing that you may want to increase the amount of disk space associated with the instance. This can be done by clicking on the "Edit Storage" link on the right hand side of the page, near the bottom. This will allow you to modify the amount of disk available to this instance. After setting the storage amount, click on "Review and Launch" at the bottom of the page. This will return you to the "Review Instance Launch" page. Click on the "Launch" button at the bottom of the page.
When you launch the instance, a dialog box appears labeled "Select an existing key pair or create a new key pair". If you have used AWS instances previously, then a key pair file should show up in the selection menu, otherwise you will need to create a new one. You can also create a new key pair even if some old ones are available. To create a new key pair, select the "Create a new key pair" option in the menu list and type in a name for the key pair file. The dialog will warn you to make sure that you save the key pair file after you create it. After typing in the key pair file name, click the "Download Key Pair" button. The key file will now be in your download area with the name filename.pem, where "filename" is the name you put in the name field for the key file. You will need to copy this file to what ever platform you are planning to use to access your AWS instance. Once you have created the key file, click on the "Launch Instance" button. This will take you to the "Launch Status" page. At the bottom right of the page, click on the "View Instances" button. You will then be taken to the EC2 Dashboard page, except that now you will see the "Instances" that you have access to. You can get to this page by going directly to the EC2 Dashboard page and clicking on the "Instances" link under the "Instances" tab. You should see a new instance appear and after a minute or two, it should have the status "Running". Note that once an instance is "Running", you are being charged for whatever resources are required by the instance. You can stop an instance by going to "Actions" menu at the top of the page, selecting "Instance State", and then selecting "Stop" under the submenu. This will halt the instance, and you will only be charged for storage.
Once an instance has been created, you can start and stop it repeatedly by selecting the instance, going to the "Actions" menu and clicking "Start" or "Stop" under the "Instance State" submenu. Each time you start an instance, an IP address should appear in the "Public IP" field for that instance. This address can be used to SSH into the running instance from some other computer. Once an instance is running and has an IP address, it can be accessed from another computer just like any Linux workstation or cluster. When you first create an instance, it will always have an account called "ec2-user". This user name can be used be to log into the instance from another computer.
From Linux: This is the simplest platform to log into to your AWS instance. Copy the key pair file that you are going to use to a directory on your Linux platform that you would like to use for logging in to the AWS instance and then type
ssh -i keyfile.pem -l ec2-user ip.add.re.ss
where keyfile.pem is the key pair file name and ip.add.re.ss is the numerical IP address in the "Public IP" field on the EC2 Dashboard page. This will log you in as user ec2-user.
From Mac The Mac is almost the same as for a Linux box. Bring up a terminal on the Mac and go to whatever directory contains your key pair file. Use the above SSH command to connect to the remote instance.
From Windows Still figuring this out.
