Software Stack Components

We agreed at our Mar'13 PI meeting to generate tables of technology/issues for the various software stack components, as we did for the Languages component below. Please coordinate with your co-PIs and with other projects working on the various software stack components to generate tables for the topics below. If the lead shown below is incorrect, please correct.

• DSLs - Saman Amarasinghe and Dan Quinlan
• Scientific Libraries - Milind Kulkarni
• Languages - Katherine Yelick
• Compilers - Dan Quinlan
• Libraries - Sanjay Kale
• Runtimes (application-facing) - Shekhar Borkar
• Runtimes (os/hardware-facing) - Ron Brightwell
• Operating Systems - Pete Beckman
