In the CUDA parallel programming model (shown in Fig. 2), each thread has a per-thread private memory space used for register spills, function calls, and C automatic array variables. Each thread block has a per-
Regardless of the model you use for runtime contexts, youcannotshare a runtime context between multiple threadsat the same time. If two or more threads attempt to use the same runtime context simultaneously, a runtime error occurs. Multiple Threads Sharing a Single Runtime Context Figure 11-2...
Fork-One ModelAs shown in Table 5–1, the behavior of the pthreads fork(2) function is the same as the behavior of the Solaris fork1(2) function. Both the pthreads fork(2) function and the Solaris fork1(2) function create a new process, duplicating the complete address space in the...
When it detects a multithreaded program,dbxtries to loadlibthread_db.so, a special system library for thread debugging located in/usr/lib.dbxis synchronous; when any thread or lightweight process (LWP) stops, all other threads and LWPs sympathetically stop. (An LWP is a thread in the Oracl...
We focus on monitoring thread synchronization behaviors, which reflect application performance, and thread deadlocks, which reveal errors in applications.We make three contributions in this thesis. First, we develop a directed acyclic graph (DAG) model for quantifying the criticality of instructions on ...
My Library show interesting performance from 1 to 4 core, I use a kind of data parallel model to dispatch work on multiple core. Since yesterday, We try our demo on a corei7 and the performance are not so great...On my quadcore, from 1...
Solving 11 Likely Problems In Your Multithreaded Code Joe Duffy Concurrency is everywhere. Server-side programs have long had to deal with a fundamentally concurrent programming model, and as multicore processors become more commonplace, client-side programs will have to as well. Along with the ...
Prevailing trend in design of chip multiprocessors (CMP) has been that single-core processors are replicated. Therefore, they typically define asynchronous computational model, require heavily locality-aware memory allocation, and present high overheads in intercommunication. This kind of properties make pa...

2. Geant4MT Data Model 3.3 Custom Scalable Malloc Library The parallel slowdown for the glibc default malloc library is reproducible through a toy program in which multiple threads work cooperatively on a fixed pool of tasks. The task for the toy program is to allocate 4,000 chunks of size ...
