kandi X-RAY | StarPU Summary

StarPU is a C library typically used in Hardware, GPU applications. StarPU has no bugs, it has no vulnerabilities, it has a Weak Copyleft License and it has low support. You can download it from GitHub.

++=================++ || i. introduction || ++=================++. +--------------------- | i.a. what is starpu?. starpu is a runtime system that offers support for heterogeneous multicore machines. while many efforts are devoted to design efficient computation kernels for those architectures (e.g. to implement blas kernels on gpus or on cell's spus), starpu not only takes care of offloading such kernels (and implementing data coherency across the machine), but it also makes sure the kernels are executed as efficiently as possible. +------------------------ | i.b. what starpu is not. starpu is not a new language, and it does not extends existing languages either. starpu does not help to write computation kernels. +--------------------------------- | i.c. (how) could starpu help me?. while starpu will not make it easier to write computation kernels, it does simplify their actual offloading as starpu handle most low level aspects transparently. obviously, it is crucial to have efficient kernels, but it must be noted that the way those kernels

Use a configure substitution in `lib_LTLIBRARIES`

Asynchronous enqueueWriteBuffer not executed on Intel OpenCL for iGPU

QUESTION

Use a configure substitution in `lib_LTLIBRARIES`

Asked 2019-Apr-19 at 20:23

I am trying to implement with Autotools a “multiversion option” for my shared library: in case the user enables it, the library must be able to cohabitate with other versions of itself. That means that the name of the binary must contain the version string, or at least any string that distinguishes it from other versions.

libtool has an option, -release, which does exactly that. However, as explained here, this will not work for my purpose, because at least one file will not have any suffix appended and this will create conflicts with other versions of the package:

4.3. Multiple libraries versions
While libtool was designed to handle the presence of multiple libraries implementing the same API (and even ABI) on the system, distributions made that necessity moot. On the other hand, it is not uncommon for multiple versions of a library to be installed, with multiple API implemented, allowing consumers to pick their supported version. This is the case, for instance, of Gtk+ and Glib.

The first reaction would be to combine the two options, -release and -version-info; this would, though, be wrong. When using -release the static archive, the one with .a extension, the libtool archive (see Section 6, “Libtool Archives”) and the .so file used by the link editor would not have a revision appended, which means that two different version of the library can't be installed at the same time.

In this situation, the best option is to append part of the library's version information to the library's name, which is exemplified by Glib's libglib-2.0.so.0 soname. To do so, the declaration in the Makefile.am has to be like this:

I don't understand why -release won't work for you, so I'll just leave that solution out of this answer. The procedure is similar, but will create different .so file names (e.g. libfoo-1.2.so and libfoo.so) but the same .a name.

OpenCL commands enqueued by clEnqueueXXX do not start execution, until you call clFlush or clFinish functions.

clFlush basically moves all commands from CL_QUEUED state to CL_SUBMITTED state (see clGetEventInfo documentation for a list of all states).
clFinish does the same as clFlush, but also blocks until all commands in a queue finish execution.

In your example, you should add clFlush call before the loop to make it work.

Edit: some OpenCL implementations can do an implicit clFlush after enqueue, so a command can start right after clEnqueueXXX call. This is not portable, and for general case, you should still use clFlush or clFinish.
