Dynamic allocation of CloVR VM instances to a cluster on the cloud running BLAST. A cluster of CloVR VMs is deployed on-the-fly and scaled to 160 c1.xlarge Amazon EC2 instances (totaling 1280 virtualized CPUs) running BLAST of a random sample of ~100 Million nucleotides from metagenomic whole-genome shotgun sequencing with 454 Titanium FLX of an unpublished oral microbiome project against the NCBI non-redundant protein database.
