During fall 2010, we updated the CRdata libraries to R version 2.12.1 and Bioconductor version 2.7.

We typically advise users to launch multiple CRdata nodes and perform large-scale data analyses in parallel. However, some CPU-intensive packages would benefit from more powerful processor nodes.

This month, to accommodate users who need more CPU power per node, we have added a High-CPU Instance to our list of available node types.

For the moment, we are providing the following 2 node types, while we explore the use of multiple virtual cores per CRdata node.

Small Instance – m1.small

1.7 GB memory
1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit)
160 GB instance storage
32-bit platform
I/O Performance: Moderate

High-CPU Medium Instance - c1.medium

1.7 GB of memory
5 EC2 Compute Units (2 virtual cores with 2.5 EC2 Compute Units each)
350 GB of instance storage
32-bit platform
I/O Performance: Moderate
