cuda 编程

//GPU的内存空间和CPU的内存的空间是分离的需要将数据来回转移这样看来 GPU对整个主机而言就是一个外设在OS中也确实是这么实现的可以用lscpi查找GPU设备
cudaMemcpy(d_a, a, numBytes, cudaMemcpyHostToDevice); // Synchronous function, no overlapping allowed.
kernelFunctionName<<>>(arg1, arg2, ..., arg n); // Asynchronous, we can take advantage of overlapping.
//Host code during device execution
...

// End of the overlapped host code. Waiting for the end of the kernel execution to transfer data between the host and the device. cudaMemcpy(a, d_a, numBytes, cudaMemcpyDeviceToHost); // Synchronous function, no overlapping allowed.

SGE Sun Grid Engine性能调优

anneng — Thu, 05 Nov 2020 08:54:07 GMT

一，SGE现状
http://gridengine.org
SGE最初是Sun的产品，被Oracle收购后，命运和Java一样。
两个开源版本：
“SON OF GRID ENGINE” https://arc.liv.ac.uk/trac/SGE
“OPEN GRID SCHEDULER” http://gridscheduler.sourceforge.net/
两个商业版本：
“UNIVA GRID ENGINE” http://www.univa.com/products/grid-engine
“ORACLE GRID ENGINE” http://www.oracle.com/us/products/tools/oracle-grid-engine-075549.html

二，SGE和Hadoop的性能对比
