| What are the key system calls / features that you need OS/R to support? Examples: exit, read, write, open, close, link, unlink, chdir, time, chmod, clone, uname, execv, etc. | (EXPRESS) | (TG) | (DEGAS) | (D-TEC) | (DynAX) | (X-TUNE) | (GVR) | (CORVETTE) | SLEEC | (PIPER) |
| Does your project implement it's own lightweight thread package, or does it rely on the threads provided by the OS/R? If you implement your own threads, what are the key features that required developing a new implementation? If you don't implement your own thread package, what are the key performance characteristics and APIs needed to support your project? | (EXPRESS) | (TG) | (DEGAS) | (D-TEC) | (DynAX) | (X-TUNE) | (GVR) | (CORVETTE) | N/A | (PIPER) |
| Do you currently view virtualization as a key requirement to support your x-stack project? If so, why? | (EXPRESS) | (TG) | (DEGAS) | (D-TEC) | (DynAX) | (X-TUNE) | (GVR) | (CORVETTE) | N/A | (PIPER) |
| What energy/power and reliability APIs do you expect from the OS/R? | (EXPRESS) | (TG) | (DEGAS) | (D-TEC) | (DynAX) | (X-TUNE) | (GVR) | (CORVETTE) | N/A | (PIPER) |
| Please describe how parallel programs are "composed" within your project, and what APIs and support is required from the OS/R? | (EXPRESS) | (TG) | (DEGAS) | (D-TEC) | (DynAX) | (X-TUNE) | (GVR) | (CORVETTE) | N/A | (PIPER) |
| What is your model for extreme-scale I/O, and how do you expect the OS/R to support your plans? | (EXPRESS) | (TG) | (DEGAS) | (D-TEC) | (DynAX) | (X-TUNE) | (GVR) | (CORVETTE) | N/A | (PIPER) |
| Does your project include support for multiple, hierarchical, memory regions? If so, how will it be allocated and managed, by your xstack project or my the OS/R? What APIs do you expect the OS/R to support complex and deep memory? | (EXPRESS) | (TG) | (DEGAS) | (D-TEC) | (DynAX) | (X-TUNE) | (GVR) | (CORVETTE) | N/A | (PIPER) |
