We Need Your Support
As an individual or an organization you can support our effort in several ways.
Obviously, you can
PTR working group
and participate in the ongoing discussions about PTR.
If You Work for an HPC Vendor
We need your help in providing the users with the most efficient
timing mechanisms for your company's platform(s).
We also realize that you have constraints in terms of maintenance,
product support, and so forth. Therefore, Ptools is willing to make
your routines or mechanisms available "anonymously" to the general
community. That is, your company will not need to assume any responsibility
for the accuracy or longevity of the mechanism.
There are three ways you can supply the needed mechanisms:
Vendors may choose to support the project at any level, although implementation
priority will be given to those who provide higher level support. Regardless
of the level of support, vendors will be asked to provide information about
the accuracy and overhead associated with the functions.
- LIBRARY: Provide a complete, C- and Fortran-callable library that
conforms to the syntactic and semantic description of the API.
- RAW CODE: Provide assembly level routines or existing function
calls that conform to the semantics; project personnel will add
the wrappers needed to make them compatible with API syntax.
- MECHANISM ONLY: Provide assembly level code sequences, or
advice about what sequences would be best, to offer high
accuracy and low intrusiveness; such sequences need not conform
precisely to the semantic specification. Project personnel will
make the needed changes.
If You're an HPC User
We need users' help in
- Defining the application programmer's interface (API)
- Testing the library on various target platforms: see the current list of
