https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Computer-Selection-for-MKL-Pardiso-Operations/m-p/806438#M3461 <P>Hi,<BR /> <BR /> I have an extensive use of MKL libraries. I am using PARDISO for my applications. At present, our system configuration is SGI with 8 single core processors and total memory is 32 GB. <BR /> <BR /> Our problem size is very large (1.5 million degrees of freedom). Total number of right hand side (RHS) vectors is in the range of 15000. At present I am solving the problem by taking around 100 RHS at a time, and therefore it takes at least a week to finish the 15000 RHS.<BR /> <BR /> We are planning to buy a new computer system that will reduce this processing time (by solving more RHS at a time). My question is can I reduce this time from 8 days to 2-3 days? Is this possible if I go for 128~256 GB of memory from 30 GB?<BR /> <BR /> I have selected following systems at present,<BR /> 1. Intel Xeon E5-2670(8 cores, 2.6 GHz, 128 GB Memory) - total 16 cores<BR /> 2. Xeon Processor (4 cores, 1.86 GHz, 128 GB Memory) - total 16 cores<BR /> <BR /> which of the above will do the job faster? Is there any other suggestion like Xeon E5-4650?<BR /> <BR /> Thank you very much.<BR /> <BR /> Regards,<BR /> Mital</P> Thu, 07 Jun 2012 17:05:48 GMT Mistry__Mital 2012-06-07T17:05:48Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Computer-Selection-for-MKL-Pardiso-Operations/m-p/806438#M3461 <P>Hi,<BR /> <BR /> I have an extensive use of MKL libraries.
