<p>Dear Sir:</p>
<p> </p>
<p>I was wondering if anyone has tried using a high-performance I/O instance (e.g., "hi1.4xlarge") as the master node in a StarCluster cluster, with the other nodes being Sandy Bridge "cc2.8xlarge" instances. When I bring up a single "hi1.4xlarge" instance
outside of StarCluster, there is an option to attach one or two 1-TB SSD disks, but when I bring up a cluster with "hi1.4xlarge" as the master node, the SSD disks are nowhere to be found. Is a plug-in necessary to ask for the SSD disks to be available? I
have a code that needs the fastest I/O available for writes with a combined size of 100GB during the run. I have tried single Standard and Provisioned IOPS EBS volumes, but the I/O performance to these volumes is poor, even with "pre-warming". Has anyone
written a plug-in for using striped volumes in StarCluster? I would appreciate any comments or pointers to information.</p>
