• ptask / qmem

** Abstract

• ptask: parallel task scheduler for C programmer
• qmem: thread-safe queued memory manager for C programmer

** License

Same license as Ruby (CRuby/MRI) Interpreter 1.9.3 or later.

** ptask

TBD

** qmem

*** Usage

qmem_t qm = qmem_create(4096 16); // 16 pages // The number is buffer size. If there are not enough buffer, // allocate a buffer which size is this number.

... void *ptr = qmem_alloc(qm, size); // allocate a size byte memory object ... qmem_free(qm, ptr); // dealocate a memory object ... qmem_destruct(qm); // If there are non-dealocated memory objects, // all of them are dealocated.

*** Assumption

• Allocation/deallocation may be FIFO manner (first allocate, first dealocation).
• Many allocation/deallocation are occured.

*** Restriction

All functions except qmem_free() must called by one thread (called master thread). Othre threads (called worker threads) can not allocate qmem. Under the restriction, qmem doesn't need any locks.
